Performance boost for X800 GT cards with R480 GPU

[ShadowFlare]

Background information

People have previously mentioned that their Powercolor X800 GT's were being improperly identified as having R423 chips, even though they have checked and found that they are indeed R480 chips. People with such cards had asked if there was a way they could get it to show as an R480 chip. They had been given responses that there was no reason to make it show as an R480 chip. I have found that this is actually not true! I did some research on it and these are my findings.

I figured out how to get the Powercolor X800 GT bios locked to 8 pipelines so I could use it to get equivalent performance to that card on my X800 GTO2, so I did some benchmarks. I found that when using the GTO2 bios rather than the Powercolor X800 GT bios at the same clock speed and both at 8 pipelines yielded at least a 100 point increase (potentially a 200 point increase) in 3dmark05 scores at X800 GT clock speeds.

The performance increase seems to have to do with the driver for an R480 chip getting better performance than for an R423 (when you have an R480 chip). Maybe a result of optimizations for the R480? BTW, I also get higher overclocks with the GTO2's own bios than with the Powercolor X800 GT bios.

An approximate 100 point increase in their 3dmark05 score was reported.

In addition to that, PastryLikeDood has reported a 700 point increase with the bios change, which increased it up to the ~4150 score that is typical after the bios flash: http://forums.techpowerup.com/showthread.php?t=6056&page=9#post48158
Other people have tried it as well and also had an increase in performance, but I haven't taken the time to count them.

The modded bios

There are a few different bioses I've uploaded for this. None of these will identify the card as an X800 GT, since ATI's driver package does not support an X800 GT with an R480, which would be why the Powercolor cards don't have it set as such.

To determine whether your card is compatible with one of these bioses, look at your fuses data in ATITool. If CONFIG_DIE_FUSES looks like 0xFFFF?FFF and CONFIG_SUBSTRATE_FUSES looks like 0xFFFFFF9? where the "?" can be any digit, then your card is a candidate for being able to accept one of these bioses. If the fuses values are like that, then pick the bios that is the closest match for your card. If one for your card is not here, then post your bios so I can modify and add it.

#1 is the second revision of the Powercolor X800 GT bios, but modified to be identified as a Powercolor X800 GTO with an R480.
#2 is an actual HIS X800 GT bios from the iTurbo version, modded to R480
#3, #4, and #5 are a modified Sapphire X800 GTO/GTO2 bios with clocks modified to X800 GT clocks and subvendor id set to the company named in the file name.
#6 is the bios for the GECUBE X800 GT, modded to R480
#7 is the bios for the Powercolor X800 GT Evo, modded to R480
#8 is the first revision Powercolor X800 GT bios, modded to R480
#9 is the bios for the Club3D X800 GT, modded to R480
#10 is the bios for a GECUBE X800 GT 128 MB, modded to R480
#11 is for the Powercolor X800 GT 256 MB with Hynix 2.0 ns memory

All of the bioses are modded to 16 pipelines, so that all available pipelines will be used (all that aren't locked elsewhere).

Try the modded bios that is for your own card first!
It seems that the Sapphire X800 GTO2 bios may possibly make the card run at least a little hotter than the original bios on the Powercolor X800 GT. The ones starting with Sapphire in the name are the Sapphire X800 GTO2 bios set to X800 GT clock speeds. Try this later if you want to see if it gives you better overclocks/better scores or not.

Note: Most of these bioses are ONLY for the 256 MB versions! If anyone has a 128 MB version not listed here, please post the bios and I will mod it.

What does you need? im spanish boy with a powercolor x800GT 256MB.
Athlon 64 3000+ 1GB DDR and nforce4
My card scores 3989 3Dmarks 05 with omegadrivers based on 5.10a at default speeds 480core/490mem.
Card can reach 610 core / 560 mem
I have photos of the core R480. and 2ns samsung mem.

[ShadowFlare]

There isn't anything I need; I was just pointing out something that could give a performance increase and also possibly help with overclocking on that card. If you want to try out that bios, post your results here.

[ShadowFlare]

Update:

I tried the Connect3d GTO bios and it worked on my GTO2, but it lowered my 3dmark05 score and my max overclock.

[ShadowFlare]

My research on this seems to be correct, one person has attempted it so far and got a 3dmark05 score almost exactly matching what I got in my tests!

The new bios gains 100 more in 3dmark2k5 :)

Anyone else want to try it out?

BTW, does anyone know if there are any X800 GTOs with R480 chips that are improperly identified as R423? It probably isn't as likely, but such cards could possibly exist. If such a card does exist, it could get the same performance benefits by changing the bios to recognize it as R480.


There seems to be at least a few different versions of the Powercolor X800 GT. While all have R480 chips, some come with 2.0 ns memory, while some come with 1.6 ns memory. Also, some seem to have a temperature sensor, while others don't. Another version also has a newer bios than some do. This bios is set to 8 pipelines, and the older one is set to 16; this doesn't really make a difference on this card, though. The newer bios seems like it gets better memory overclocks (at least on 1.6 ns memory, I don't have a card with 2.0 ns memory to test with).

[ShadowFlare]

I've uploaded another bios with it identified as an HIS card. This is for the HIS X800 GT non-IceQ version which has been reported to have an R480 chip. Someone who has this card please post the real bios for that card, so that I can do a mod on that one, too. :) Also post whether it has 1.6 ns or 2.0 ns memory, if possible.

I've noticed that there's been several downloads of the Powercolor.X800GT_16P.256.Samsung20_050726 bios I posted. If you've tried using this bios on the Powercolor X800 GT, please post your results. I'd like to know if there are any other people who have had it boost the performance at least a little on their card.

[mrvomit]

my is an iceq II,labeled as 423 chip.
uff that's frustrating ,it costed more than "not-iceq" version..very bad thing,grr

So i can't use your His bios as could be dangerous i guess.
I don have a pci card for recovery in the case

[ShadowFlare]

If the non-IceQ version has only 2.0 ns memory chips, yours could make up for not being able to do this because of being able to get a much higher max memory overclock, though. :) BTW, what 3dmark05 score do you get at the stock gt speeds of 472.5/492.75?

Of course, if the non-IceQ version has 1.6 ns memory chips and it does indeed have an R480 core, then when you install the same cooler and do the bios mod it could possibly be faster.

[Robin [CZ]]

So, the facts....

I had modified BIOS in my card and i got 5127 points in 3DMark 05. frequencies: 606/1212. When I flashed my card with YOUR BIOS, I wasn't able to overclock my core. The card made some unuasual noises so...

I returned old modded BIOS. (gives +14% FPS in games as Far Cry, Doom3 and so on...)

Post your original bios for your HIS X800 GT, please. I would like to do a mod on that bios then maybe you could try that.

BTW, I can't read anything off that site you posted, but it looks like you were trying a bios from an X850 card on your HIS X800 GT? Did that increase performance at all? Also, in what way did it change your max overclock?

posted by shadow:
or post your bios so I can make a custom mod just for that one. If it is the IceQ version, you probably don't have an R480.

Uhm shadow ,i still did'nt get:
If i put a modded bios ,and core is 423 ,then card can get badflashed?

Even with a custom mod? that danger can be checked by looking at the the original bios ?

I don't know the answer to that; I'm currently trying to find out the answer in this thread: http://forums.techpowerup.com/showthread.php?t=6081 If you have a spare PCI card just in case it doesn't work right, then maybe you could help me find it. Well, maybe not, since you don't know for certain which core you have, right? Well, if someone who knows that their card has an R423 helps me with figuring it out, and the results are positive, then maybe you could try it out.

[mrvomit]

never used ,i have another old but not pci, like nothing.
Grr i will stay tuned there to see ,thanks .I'm quite interested

[ShadowFlare]

There is, of course, the possibility that going from R423 to R480 in the bios on a card with R423 will work but will get worse performance.

[Steevo]

I'm up for it.

I have the R430 core. Infineon memory. Can't hurt, too much.

Hi!
I've got a PowerColor X800GT with Samsung 1.6ns Chips.

I'm afraid I don't really know which of the provided Bios' I should use?

Am I supposed to use..
a) Powercolor.X800GT_16P.256.Samsung16_050823.zip
..because it says Samsung16 meaning the 1.6ns and bios ver. 050823 or
b) Powercolor.X800GT_16P.256.Samsung20_050726.zip
..because it's bios ver. 050726?

Is the bios version actually only indicating the different memory used?

Hope you can clear up things here.

Ah, so you have one of the rare ones that has 1.6 ns chips like I used to have. I was starting to think that I had the only one. ;)

As for which bios to use, just use whichever one you want. If you are overclocking, try both, it may affect the maximum overclock. Besides a possible difference in overclocking, they seem virtually identical. They both use the same memory timings and the same fan speeds. I gave descriptions for the files in the post that contains the files, but here's a recap:

Powercolor.X800GT_16P.256.Samsung20_050726 is the actual Powercolor X800 GT bios, but modified to R480 and 16 pipelines. This won't necessarily unlock pipelines, it will just make it so that if you later do a hardware mod, you won't have to flash the bios since you would already have it set up properly for that.

Powercolor.X800GT_16P.256.Samsung16_050823 is a modified Sapphire X800 GTO2 bios with the clocks set to X800 GT clocks and the vendor ID set to Powercolor/Tul. I also posted this one because it may get better overclocks compared to the default bios for the Powercolor X800 GT, since it did on my GTO2 compared with the Powercolor X800 GT bios.

BTW, all of those I have identifying the card as an X800 GTO, since there is no such thing in the drivers as an X800 GT with an R480 chip.

[Zzzort]

Thanks!

I'll start by flashing the Powercolor.X800GT_16P.256.Samsung16_050823 bios version.

If you have 3dmark 2005 (or 2003) post scores from before and after, please. :) BTW, the performance boost isn't really much, only about a 2.7 - 5.4% increase in 3dmark 2005 scores (the percent increases with overclocking and/or unlocking pipelines). I just wanted to let people know about it, since it is basically a free performance boost; there are no side effects to it (especially when using the same bios, but only modified to R480).

There are four bioses I've uploaded for this. None of these will identify the card as an X800 GT, since ATI's driver package does not support an X800 GT with an R480, which would be why the Powercolor cards don't have it set as such.

#1 is a modified Sapphire X800 GTO/GTO2 bios with clocks modified to X800 GT clocks and subvendor id set to PowerColor/Tul.
#2 is the same, but with the subvendor id left as Sapphire.
#3 is the second revision Powercolor X800 GT bios, but modified to be identified as a Powercolor X800 GTO with an R480.
#4 is the same as #2, but with the subvendor id set to HIS.

All 4 bioses are modded to 16 pipelines, so that all available pipelines will be used (all that aren't locked elsewhere).

Note: These bioses are ONLY for the 256 MB version! If anyone has the 128 MB version, please post the bios and I will mod it.
I'm sceptical with your findings.. :) (i have the right to be lol don't get harsh ;))

i think this 100pt diff is due to the fact that 3dmark sometimes doesn't come up with same result every time

or... /and...
this new bios has tighter mem timings

but then again you could be exactly right and it is the bios firmware enabling the core to perform like a r480 instead of a r423 which there are diffs betwene those two cores but i'm not shure if the bios has any control over that though we will see..

i suggest you do a test. :)

test: run 3dm05 3 times on each of these configs
1. r480 bios x800 driver
2. r423 bios x800 driver
3. r480 bios x850 driver
4. r423 bios x850 driver

i'm not going to guess what you will find but it should be intersting. :)

btw how are you determining if these bioses are r480 or r423? cause everst and alot of other programs don't read from the bios they read from the driver :)

more questions: how did you mod these bioses to 16 pipes? (i already know how to do it btw i'm just wandering if you did it right)

btw i think you should have left the device /vendor id's alone as they don't affect the cards performance and changeing them often causes problems

[ShadowFlare]

i think this 100pt diff is due to the fact that 3dmark sometimes doesn't come up with same result every time
I've run 3dmark 2005 on it many times with different bioses and different IDs, all the results point to the same conclusion. On a bios that identifies the chip as an R423, simply changing the hardware ID so it will be identified as an R480 will change what score it gets in 3dmark 2005. It goes the other way around, too, changing it to an R423 on a bios that was R480 will have the same impact on performance.

Anyway, with higher clocks and more pipelines, the difference is more like 300. 3dmark 2005 scores don't vary THAT much when testing it more than once with the same settings. Besides, I've never seen my scores vary even by 100 on the same settings.

or... /and...
this new bios has tighter mem timings
Since I've had the same result when using the same bios and only changing the ID, I know for certain that it has nothing to do with memory timings.

but then again you could be exactly right and it is the bios firmware enabling the core to perform like a r480 instead of a r423 which there are diffs betwene those two cores but i'm not shure if the bios has any control over that though we will see..

It probably does have to do with the driver and only that, but changing the ID is the only way I know of to have it use the part of the driver for an R480 or for an R423. Maybe some driver mods could be done to get the same performance without flashing the bios.

btw how are you determining if these bioses are r480 or r423? cause everst and alot of other programs don't read from the bios they read from the driver :)
I am just basing it off of what ATITool says when that bios is in use.

more questions: how did you mod these bioses to 16 pipes? (i already know how to do it btw i'm just wandering if you did it right)
I used a hex editor to modify the byte as offset 0x7A so that the second hex digit was zero. Before doing this for the first time, I first checked to make sure it looked like a CONFIG_ROM_FUSES value (from ATITool). That value seems to be in the same place for all the bioses I've seen so far. After doing that modification, I opened the bios in RaBiT and saved it; this was to fix crc and/or checksum values that need to be changed when modifying the bios. I've thoroughly checked this and found that it does produce the same bios as if you had modded the bios through flashing the bios in such a way that you would to change the pipelines, but preserve the rest of the bios.

btw i think you should have left the device /vendor id's alone as they don't affect the cards performance and changeing them often causes problems
The device ID is what I changed to make it be detected with an R480 chip. I also changed the subsystem ID and subvendor ID to match up with values in the .inf file for the driver. As long as you use values that match up with ones in the .inf file for the driver, it will be detected with a proper name. So far, I haven't had any problems with changing this on my card. The worst that ever happened was that Windows just could not install a driver for it.

That's right, your's does have 1.6 ns memory chips. Make a backup of your bios first. If you want to still be using an actual Powercolor X800 GT bios, flash the one that says Powercolor in the name, Samsung20, and has an older date. All the others are just modded X800 GTO2 bioses. If you are going to try overclocking, try it with either of the them. The amount you can overclock may be different between the two.

Here is a guide for video bios flashing: http://forums.techpowerup.com/showthread.php?t=11

BTW, is this the one with the green on the heatsink or the red one? The red one (extreme edition, I think) is guaranteed to have 1.6 ns memory chips, but then the green one has them sometimes, too. There are three people I know of so far that have said their's has the 1.6 ns chips (mine was one of them). I guess the green one having them is less rare than I thought. ;)

So you were lucky and got one of the ones with 1.6 ns chips on the one that isn't guaranteed to have them. :) If you change the heatsink/fan for something better and put ramsinks on the memory, you'll have a card better than the extreme edition that I mentioned. :)

You shouldn't have any problems having to do with memory for either of them. If you go with the one labeled Powercolor.X800GT_16P.256.Samsung20_050726, you will have the bios designed for the card you have, but just modified to R480; so there will be no problems there. It may not actually be the exact same bios; it could be a newer version of the bios than the one you have, but that shouldn't cause any problems, since it is still for that type of card. If you go with the one labeled Powercolor.X800GT_16P.256.Samsung16_050823, you will have one that was from a card with 1.6 ns chips. Either way, you will have one that works. If you are not going to overclock, I'd go with Powercolor.X800GT_16P.256.Samsung20_050726. If you are going to overclock, try both and use whichever gives you the best overclock. :)

Oh...one more question

I use a X850XTPE edited in RabiT 1.7 ... I low the memo and core to 472 and 492...

my temps get a little more high now ... is because the bios ? I see the temp in Rivatuner.

There´s something to do with the fan to control this ?

I don´t overclock nothing and used the default temps from my original bios.

[SPHERE]

I am just basing it off of what ATITool says when that bios is in use.
look at the loging in rabit ;)

I used a hex editor to modify the byte as offset 0x7A so that the second hex digit was zero. Before doing this for the first time, I first checked to make sure it looked like a CONFIG_ROM_FUSES value (from ATITool). That value seems to be in the same place for all the bioses I've seen so far. After doing that modification, I opened the bios in RaBiT and saved it; this was to fix crc and/or checksum values that need to be changed when modifying the bios. I've thoroughly checked this and found that it does produce the same bios as if you had modded the bios through flashing the bios in such a way that you would to change the pipelines, but preserve the rest of the bios. humm.. that may work have you tested all of those bioses? using the moded flashrom on a less than 16 pipe card?

the way i do it is bt using the non moded flashrom to flash it to a already 16 pipe card and that changes it then i simply save the rom from the card and flash back

The device ID is what I changed to make it be detected with an R480 chip. I also changed the subsystem ID and subvendor ID to match up with values in the .inf file for the driver. As long as you use values that match up with ones in the .inf file for the driver, it will be detected with a proper name. So far, I haven't had any problems with changing this on my card. The worst that ever happened was that Windows just could not install a driver for it. I used to think the same exact thing but that doesn't always apply ;) but you may be right that it would work on x800's cause i don't think it has a locked device id like other cards like 9700's 9600,s ect. :)


the way you change drivers is go into device manager / update driver/no not at this time/install from list~/dont search~/uncheck show compataple h/w

That's why you should use one of the modded bioses I posted. ;) BTW, I see from your scores that you got the performance boost for going to an R480 that I was talking about.

[ShadowFlare]

look at the loging in rabit ;)
All that matters is what the driver says, since that is when there is the change in performance.

Yes, I've tested all of them. Besides, it's very easy for me to tell when that is the right value to change or not. You're talking to someone here with lots and lots of binary file modding experience. ;)

Yes, it does work at least on X800/X850 series cards to change the ID. That's all I have experience with for bios modding so far.

I'll try it and see if it works and if it gets the equivalent performance boost.

[ShadowFlare]

ok :)

i was talking about how you tell what core the bios is coded for
You can see what a bios originally was by looking near the beginning of the file with a text editor or hex editor. It will usually say it in plain text, like it will say R423, R430, R480, etc.


ok lol where did you learn how to do all this? :)
I learned it on my own. :) Mainly my experience with modding binary files comes from mods for game data files.

BTW, I tried using the X850 XT PE driver with the Powercolor X800 GT bios as you said I should try and I did not get the R480 performance boost.

[maccrow]

??? Did you get it unlocked to 12 pipelines before?

no but I´m trying get 12.

I get the bios indicated by you and here the score in 3dMark2005

X800GT R480 - 4130
memo/core default and the temps low to max 45oC :eek:

Well, from the 3886 I get with the original bios, its good, dont ? =)

[ShadowFlare]

I don't quite understand what you mean. Are you saying that the temp. is lower or higher?

BTW, I'm not sure why, but it seems like the Powercolor X800 GT bios may be consistently getting scores about 10-15 points lower than bioses that were intended for R480 chips (I also got about 4130 with that bios and a little above 4140 with another). That amount of difference is almost nothing, though.


One more thing; you wouldn't happen to be the person to whom I sold my Powercolor X800 GT with 1.6 ns memory chips, would you? He's also from Brazil. Heh, probably not, since when I mentioned this bios mod to him he said he didn't want to try it.

[maccrow]

My temps with the X850XT or XTPE are 59-62C and now using the bios Sapphire.X800GT_16P.256.Samsung16_050823.zip I get temps like 39-45C.

And now I see that I used a wrong bios .. uops...I ll try the Powercolor now.

Heh, if you intended to use the one saying Powercolor and Samsung16, it won't make any difference except that in programs that will show the subvendor ID, it will be Powercolor instead of Sapphire after you change the bios again, since it is only a mod of the other just to change the ID for the maker of the card. The 3 bioses I posted with Samsung16 in the name are all the same bios, just with different ID's for the card's maker. The only one that is actually different is the one with Samsung20 in the file name.

Of course, you could flash it to the one with the subvendor ID modified just to have it be IDed as a Powercolor card, but there will be no need to retest anything.

BTW, the difference in temps is probably caused by different fan speeds that are set in the bios. That's the main reason I was recommending using one of those; they use the same fan speeds.

[SPHERE]

So shadowflare where do you think this performance is coming from? (it doesn't seem to be the drivers.. or is it :confused:)

[ShadowFlare]

So shadowflare where do you think this performance is coming from? (it doesn't seem to be the drivers.. or is it :confused:)
I still think it's from the drivers; it just seems to only be able to be forced as an R480 in the driver if the bios actually says it is one. Driver mods may be able to get around this, though.

Which XT? X800 or X850? I'm assuming probably X800 because of the clock speeds you mentioned. Since Powercolor said they would only be using R480 cores on their X800 GT's, I'm sure your's has it, too. Try using one of the bioses I posted. It will get better performance than an X800 XT bios on that card. Also, using the X800 XT bios would severely limit your memory overclock and possibly gpu overclock (at least from my experience with my GTO2).

BTW, also post your original bios so I can take a look at it.

Hmm, interesting. According to someone there, Powercolor made an R480 bios for their X800 GT and has made it available. I've never seen that before. However, I remember when I looked at the original of the second revision bios that I posted a mod of, there was something with R480 that showed up in the bios file. I tried the bios file and it still got detected as an R423. I wonder if this is the bios they speak of? If so, there's nothing really special about it; I got the same 3dmark05 scores with it as I did with the older one.

I've finally found some answers regarding what this type of mod from R423 to R480 in the bios does on a card with an R423. Take a look here: http://forums.techpowerup.com/showthread.php?t=6081

I posted a link there to a topic where someone tried it. They found that there is no change in performance between having it ID'ed as an R423 or R480 on their Connect3d X800 GTO.

This could actually be a way of finding out whether a card has an R423/R430 or R480 without taking the heatsink off. :) If there is no performance change from changing the ID between an R423 and R480, then it is not R480. ;)

Hi, I have followed this post for a couple days now and was wanting to wait and see more peoples results before I did the flash, but I figured oh well might as well do it. So there's good news and bad news. I have a Powercolor x800 GT with 1.6ns mem and r480. Results:

3Dmark2k1 (609mhz core/600mhz mem):
before- 23269
after- 24546

Obviously that is a huge boost in performance but, I was unable to run 2k3 or 2k5. 2k3 gives me an error reading: "Hardware does not support compressed textures (DXT1 and DXT3). 3DMark03 will not run properly." No test are supported in 2k3. 2k5 gives me an error report reading: "Your hardware does not support the features required to run 3DMark05. Pixel Shader 2.0 (or higher) is on of these. 3DMark05 is thereby not a suitable benchmarking tool for your system. Please use 3DMark 03 for benchmarking Pixel Shader 1.x hardware or 3DMark2001 SE for DX7 class hardware." No tests are supported in 2k5 either.

I have not reinstalled drivers and I believe I have catalyst 5.9's. I will try the latest and see if that fixes the problem, but if not then I guess I will have to flash back :( although I would really like to see what this would do to my 03 and 05 scores. If you have any suggestions they would be greatly appreciated. Thanks.

BTW, I use the Powercolor.X800GT_16P.256.Samsung16_050823.bin bios, no additional pipes were unlocked, and ATITool does now correctly identify my card as r480.

So i pencil modded the voltage from 1.81 to about 2.05 and I got 600 easily. After that my card was running a little hotter around 48c idle. So i took an old cpu cooler I had and modified it to fit the radeon card, after that I was super cool and I was able to push my core all the way to around 615-620 stable. Before the bios flash with all the same settings, I was able to get a little over 5000 in 3DMark05 with clock speeds at 550/600.

DewiL: You have an HIS X800 GT with the IceQ cooler, right? According to what has been found in another thread, you shouldn't have any problems with having your chip IDed as an R480 even if it is only an R423. Also, flash with the modified flashrom so you can see if it will also give you 12 pipes. As mentioned previously, I've also modded all these bioses to 16 pipelines so they will unlock any that are unlockable with a bios flash. If it does mod to 12 pipelines, besides showing up as an X800 GTO, it will run as fast as one, too. :)

I tried the Powercolor bios with Samsung 2.0ns mem and it didn't really change anything from the old bios, except maybe running a degree or two cooler, but that could be due to my ambient temp being lower right now. My 3dmark scores were so close together with the 1.6ns and 2.0ns bios that it is more than likely to be within margin of error.

Ill try the first one! WooHoo! Im glad to see that this worked for me though!

[T-800]

WooHoo! Success!!! I flashed my vid card successfully so it now recognizes an R480 core! It crashes though because the card gets real hot now though... Not OC'd... Maybe i flashed with the wrong BIOS though.. It is recognized as an X800GTO in desktop properties and an X850 Pro!!! Sweet!



I may be consider getting an Arctic Cooling HSF though...

hi yes thats normal i buy the Zalman VF 700 CU for my card
use the mod bios top of the post :o

[PastryLikeDood]

Powercolor.X800GT_R480_16P.256.Samsung20_050726.zi p

This is the correct BIOS to flash with right (because its the one i JUST reflashed with) Hopefully my temps will go down now!

What does everyone think of the Arctic Cooling ATi Silencer for the X800 series? I hear their pretty good. and for only $30.00.... it doesnt seem like a bad price to me!

[T-800]

shadow: I will try the Samsung 2.0 bios as soon as i get a chance and report how it goes.

t-800: vmem, vgpu, and igpu mods are all explained here http://www.techpowerup.com/articles/overclocking/voltmods/112 . I just did the pencil mod because I was only getting around 500/550 stable on stock cooling but i knew that my memory was rated for 600 mhz so i wanted to at least get that out of it. So i pencil modded the voltage from 1.81 to about 2.05 and I got 600 easily. After that my card was running a little hotter around 48c idle. So i took an old cpu cooler I had and modified it to fit the radeon card, after that I was super cool and I was able to push my core all the way to around 615-620 stable. Before the bios flash with all the same settings, I was able to get a little over 5000 in 3DMark05 with clock speeds at 550/600.

hi first thx 4 ur replay
thats was what i want to now u right i have about 535/540 max core with normal cooling
by doing bench system crash in the middle i geht articats the card going too hot.
now i have buy new cooling Zalman VF 700 CU i hope i get it soon than i have to think how can i cool the mem hmm but later
now about the vmod i look allready the vmod post but i cant find the point todo the pancil
witch PCB layout should i use for the mod and can u tell me easyley where is the points on my Powercolor x800 Gt
Big THX :rolleyes:

i have also thinking about new artic cooling but i have read that they some poeple have problem fitting i dont really now about fiitig on x800 Gt cards
thats whay i buy the Zalman VF 700 CU :o

Interesting... Well... time for me to get a new HSF for my GPU.. when i get the extra money:ohwell:

[ShadowFlare]

I tried the Powercolor bios with Samsung 2.0ns mem and it didn't really change anything from the old bios, except maybe running a degree or two cooler, but that could be due to my ambient temp being lower right now. My 3dmark scores were so close together with the 1.6ns and 2.0ns bios that it is more than likely to be within margin of error.
Did you see if your max overclock went back to normal or not? BTW, what date is shown for your original bios if you open it in RaBiT 1.7? If it is 07/15/05, use RaBiT to set the IDs in that bios to the ones I used then try that bios.

Maybe it won't really change at all, though. It could be that what causes the performance boost makes the gpu actually get utilized more than before and that could be the sole cause of the temp. increase. That could actually kind of coincide with that your max overclock went down to a point where the performance was roughly equivalent.

[ShadowFlare]

BTW, I used to actually have a Powercolor X800 GT. It had the 1.6 ns memory and with stock cooling it could overclock to 560/526 with no artifacts. It could even get all the way to 576/555 without ever crashing and with only minimal artifacts such that they couldn't be detected visually, only by using something like ATITool. With a different cooler, it probably could have reached clock speeds beyond even that. At those clock speeds, I got a 3dmark05 score of 4750, which was long before I found out about the speed difference with it used as an R480.

After I got my GTO2, I sold that card, though, since it could never match the performance that my GTO2 could get, even though the gpu on mine couldn't clock nearly as well as that GT I had. ;) My max is 520 on the gpu and crashes beyond that without ever showing any artifacts before crashing.

[frisK]

T-800: look at the attached pic to see which resistor needs to be traced for the volt mod. make sure to have a multi meter to check to drop in resistance.

Shadow: My max overclock was still lowered but the scores were close to identical. I think the new bios does in fact make full utilization of the cpu because my temps are a lot further from idle-> load than before. I dont have my original bios with me but when i get home i'll look at it.

BTW, do you have cooling for your memory? If you have ever touched the memory chips while it is at load, you would notice that the memory chips get hot to the touch.

Ya I do actually :P, thats not my card in the pic (I'm assuming thats why you asked) and I kinda forgot to cite my resources. That pic is from xtreme resources review of the powercolor x800gt.

[PastryLikeDood]

Hrm... I wonder if my card is supposed to have no bracket on the back for the screws....? Because it doesnt...

Oh well... Once i get some extra cash i will buy some new cooling for it (i think my RAM was crashing my system...)

Using ShadowFlare's modified X800GT bios.. i successfully flashed my card to the R480 core...

Heres the rundown.. Sure, the card runs a tad warmer... but get THIS!

Before flash i got 3489 in 3DMark05... with this setup
AMD Athlon 64 3000+ @ 2.3GHz
1GB Corsair RAM DDR400
PowerColor X800GT 475 core/ 490 mem (not overclocked)

After flash i got 4152 in 3Dmark05 with this setup
AMD Athlon 64 3000+ @ 2.0GHz
512MB Corsair RAM DDR400
PowerColor X800GT(identified as GTO with R480 now) 475 core/ 490 mem (not OC'd)

Hrm... was taking 5 minutes to flash the bios and gain a tad under 700 points more worth it?

YES IF I DO SAY SO MYSELF

NOTE : I had to use flashrom to do the flash... atiflash kept messing up... it got a write fail at 4/10000 bytes...so i tryed flashrom and it worked like a charm.

Also, note that where i circled it reads "X800GTO" before it read as X800GT (or maybe SE i cant remember)

hi,
I've got a PowerColor X800GT with Samsung 1.6ns Chips
i want use this bios "R480_16P.256.Samsung16_050823_VendorID_Powercolor. bin" but when i open the bios with Radit1.7, in logging section, the description of connectors isn't exact, the powercolor have 2 dvi connectors + 1 tv.

modified bios :
> Connectors Layout table offs: 0xB7C9
Port = 1, Conn0 type = VGA
Port = 0, Conn2 type = STV
Port = 2, Conn4 type = DVI-I

powercolor bios :
> Connectors Layout table offs: 0xB703
Port = 1, Conn0 type = DVI-I
Port = 0, Conn2 type = STV
Port = 2, Conn4 type = DVI-I

i have modified bios in test for replace value at 0xB7C9 with DVD-I value and save.
when i want open the new bios file, radit1.7 said " bios is corrupt .... ".
i use hexadecimal editor for the test.

ShadowFlare or orther people could you help me ? or i want use wrong bios for my card ?

thanks and sorry for my english,
bye

[ShadowFlare]

As far as I know, that shouldn't really matter. You could of course not use that bios and just use the modded Powercolor X800 GT bios. If you are planning on overclocking, you could even try both and see which works best for you.

Hi, ShadowFlare,
i have question : if i send to you my original bios (samsung 1.6ns), could you modif this with your settings what you have apply in your bios " powercolor X800GT_R480_16P.256.Samsung20_050726 " or said me the way i take for modif by me (eg. transform bios R423 -> R480 and 16P).

Compare the date of the original bios on your card (shown in RaBiT when the bios is opened, or you can see it in Catalyst control Center). If it is the same date (07/26/2005), then just use that bios you just mentioned; you could still use it even if it isn't the same date. BTW, there are only two bioses I've seen for that card, the one with the date I mentioned and one that was from around 07/14/2005 or 07/15/2005 (I don't remember exactly which date).

Heh, I used to think those ones of that card with 1.6 ns memory chips were pretty rare, but since then I've heard of several people having them. Part of that was probably because no reviewer ever got one with the 1.6 ns chips, only 2.0 ns.

So is that one with R480 that is identified as R423? I'll do the mod for you and if you are sure it is an R480, then you could flash the modded bios to your card to get the performance boost mentioned in this thread.

OK, that looks like the older of the two bioses I've seen for it.

Is there any chance that the bios for 1.6ns chips and 2.0ns chips are the same one ?
That's right, there's no difference. The Powercolor X800 GT's don't have any different bios that is specifically for either particular speed of memory chip. I've heard of cards with the older bios and ones with the newer bios with either of those memory configurations.

i see in site what the 07/26/2005 is a beta bios from Tul, your bios is this ?

That bios looks like it could be the same one that I did a mod on; it has the same date and time and other stuff looks the same. There are some minor differences, like certain text in the file, but that seems to be all there is, though. They probably just made the beta bios into a release version bios. The one I modded was one that was preinstalled on one of those cards. The modded bios will give a performance boost beyond any already existing performance boost from that bios.

I don't think you will be able to unlock any pipelines. You can still get the performance boost that this thread is about. Use the Powercolor.X800GT_R480_16P.256.Samsung20_050726 bios from the first post, it is a mod of the bios that your card has.

The speed of your memory chips doesn't really matter. Anyway, I already said that it is a mod of the exact bios that is from your card. I compared your original with the original I have and it is exactly the same, not one byte is different.

That's the first confirmed one to work with it that is not a Powercolor card. BTW, how many pipelines does the card have right now, 8 or 12? I'm thinking 8, but I just wanted to make sure.

Only 8 :cry: :cry:

[ShadowFlare]

BTW, you mentioned it has 1.6 ns memory chips, right? Have you overclocked the card so far, and if not, do you plan to? If it is 1.6 ns memory chips, then you could set the speed of them much higher than what it is set at right now. The 1.6 ns chips are designed to run at or close to 600 MHz and usually can. Your card is actually set to use a lower memory speed than a normal X800 GT would use.

Did you reinstall the driver after you flashed your card?
Your GB_PIPE_SELECT doesn't match your CONFIG_DIE_FUSES. PIPE_SELECT shows 8 pipelines, DIE_FUSES show 12.

How to modify to 12/16 pipelines the Sapphire X800GT AGP 256MB card?
First I saved bios in pure DOS with "flashrom -s 0 biosold.bin" command. Then I load new flash with "flashrom -f -p 0 Sapphire RADEON X800 PRO VO ATOMBIOS 113-AA15900-101-PC.bin" command.
After reboot in Atitool 0.25 beta 10 program is visible still 8 pipelines!
I found the new "atiflash" programme in 3.9 version and in ppure DOS I type something like this:
atiflash -s 0 original bios.bin
atiflash -f -p 0 Sapphire RADEON X800 PRO VO ATOMBIOS 113-AA15900-101-PC -newbios
atiflash -f -p 0 original bios.bin
After reboot still I have 8 pipelines!
I painted also one bridge, the second bridge and both of them. Still I have 8 pipelines.

My card is based on the RadeonX800SE core
215RABCGA12F
GH1685.1
0535AA

I think this is R420 core (Atitool and Ati Control Panel gave this)

So for summary, Which Bios do i have to download to increase performace on the Powercolor X800 GT 256mb.


The modded bios

There are five bioses I've uploaded for this. None of these will identify the card as an X800 GT, since ATI's driver package does not support an X800 GT with an R480, which would be why the Powercolor cards don't have it set as such.

#1 is the second revision of the Powercolor X800 GT bios, but modified to be identified as a Powercolor X800 GTO with an R480.
#2 is an actual HIS X800 GT bios from the iTurbo version, modded to R480
#3, #4, and #5 are a modified Sapphire X800 GTO/GTO2 bios with clocks modified to X800 GT clocks and subvendor id set to the company named in the file name.
#6 is the bios for the GECUBE X800 GT, modded to R480

All 5 bioses are modded to 16 pipelines, so that all available pipelines will be used (all that aren't locked elsewhere).


Should i use the #1?
and When it shows as x800 GTO,, cant i just unlock pipes to make it 16 since X800 GTO can be unlocked, (just suggestion :D) ima try



Which program do i use to flash bio,, flashrom or atiflash?





Hope someone can find way to unlock the GT...

Use the first bios. If you want to find which would get the best overclocks, you could also try the modded GTO2 bios afterwards. Other than those two, I can't guarantee that the others will be compatible, since I haven't tried them myself. The others could possibly mess up your card; they probably won't, but there's no reason to take that chance.

As for the flash utility, you could use either, but put both the modified flashrom AND atiflash 3.09 on your disk. This way if one gives a message about a write error when flashing the bios, you will have the other tool ready so you can try again with the other before restarting the computer. (I've heard of this happening once) If you use atiflash, then be sure to use the -newbios option with it, since you do want to see if any pipelines are unlockable. All of those bioses are 16 pipeline modded ones.

do the modded GTO2 bios unlocked pipeline??

thxalot:respect:

[rcp1071]

The 2nd one doesnt work,, i used the flashrom because atiflash doesnt work with the 1st one. Should i use the atiflash for the 2nd one?
And my comp says its GTO now,, so is it GTO without the 4 extra pipes.

thxalot:respect:
It isn't any more likely to unlock pipelines with that bios than any of the others I posted; all are modified to 16 pipelines to make sure you get all the pipelines that aren't hard-locked on the card. Of course, you probably aren't going to get any more, though.

The 2nd one doesnt work,, i used the flashrom because atiflash doesnt work with the 1st one. Should i use the atiflash for the 2nd one?

Only use the 2nd one if you have an HIS card, it is intended for the HIS X800 GT iTurbo cards that have an R480 chip (which is probably not common). For the Powercolor X800 GT, I would recommend only using the mod of the bios intended for that card or the modded Sapphire X800 GTO2 bios I posted. Either of those should be OK, but I can't guarantee that the others will work right (the ones from the HIS and GECUBE cards).

And for overclocking,,, to what should i clock my card too,, should i do that FIND MAX CORE AND MEM on ATITool. I want it very stable,,,, 550 550? is that any stable?

And what is RaBiT?

Oh, so that's what you meant. If it won't let you flash the bios, just add the -f parameter to force it (same for atiflash and flashrom).

And for overclocking,,, to what should i clock my card too,, should i do that FIND MAX CORE AND MEM on ATITool. I want it very stable,,,, 550 550? is that any stable?
There isn't any certain speed it is guaranteed to reach beyond the default clock speeds, so I couldn't tell you waht your max will be. Just use the find max buttons to find the max stable clock speeds. Before doing this, I'd recommend going to the settings and entering in minimum and maximum overclocks that it will allow (mainly minimum) - just in case something messes up and makes ATITool continually detect artifacts (I've had this happen before). Set the minimum to whatever you want, but no less that half of the default speeds, then set the max to some number that you don't think your card will be able to get to, like 650 gpu, 650 memory (or higher if it does reach one of those ;) ).

And what is RaBiT?
It is a bios editor that allows you to change things like IDs for the device, default clock speeds, and default memory timings.

And how do i get those CONFIG_FUSE stuff on the ATITool? I ono where to go
Hold shift when you are clicking the settings button, then it will appear in the information part.

Been reading through this post and would like to try the bios mod you have here for my PowerColor x800gt Evo (Bundled w/Thermaltake 'Tide Water' Core Cooling + have some Zalman ZM-RHS1 Heatsinks on the 1.6ns Memory) . The default clocks for the card are higher than normal x800gt at 500/527. Therefore i was unsure if this meant it had a different bios, and whether that modified bios would be compatible or not with it?

You should try just overclocking with ATITool first to see what the limit is, and if its pretty high go for it, but be careful as a bios flash with clocks higher than stock can bork your card if it cant handle it. With clocks higher than other gt's it s bios is probably different but not by that much as you can alter clocks with Rabit and Hexeditor.

Been reading through this post and would like to try the bios mod you have here for my PowerColor x800gt Evo (Bundled w/Thermaltake 'Tide Water' Core Cooling + have some Zalman ZM-RHS1 Heatsinks on the 1.6ns Memory) . The default clocks for the card are higher than normal x800gt at 500/527. Therefore i was unsure if this meant it had a different bios, and whether that modified bios would be compatible or not with it?
It sounds like your bios is likely different. Post you bios so I can check to make sure. If it is different, I'll mod it for you.

Heya thanks for quick reply, just to clarify quickly cause i didnt make it clear; my PowerColor x800GT Evo is set at default clocks of 500/527 which as I believe are higher than the standard PowerColor x800GT at 475/490, I dont know if this means i also have a modified Bios on my card.

I can only seem to OC my card using ATITool to 540/570 before artifacts appear but this cant be due to temp can it? cause the cooling i have is good on and around the card. Was really hoping that by modifying my bios I could get better 3DMark05 Results / higher OC levels.

I have included my Bios below (i saved as *.rom then changed it to *.bin hopes all gd), thanks ShadowFlare if you could check this out for me would be great :)

Hi shadowflare,
I have a his x800gt with the iceq II/iturbo.
I am questions:
I can flasher with the mod bios my card?
Is necessary it to make the modif laser-cut or the bios reactive the pipes itself?
Dewil has you it made a success of the manipulation because I do not see any more a post
Thank you for the bios

here's my original bios

It seems to be mostly the same as the other Powercolor X800 GT bios, but it does have some differences. I've uploaded an R480 mod of it in the first post.

Thanks alot ShadowFlare m8, I have been testing the new bios out you gave me for awhile now. It flashed good and now have it identified as PowerColor x800GTO. Spent awhile running some 3DMark05 tests but found i had to lower my previous OC 540/570 to 530/560 for it to run stable, which didnt look good for improvement over old bios :rolleyes: ... until I ran 3DMark05 with the new drivers/settings and got a 400 point increase :roll: ! Tested this many times and wasnt a one off, also for PCMark05 i got a 100 point score increase, not as major but thats expected from PCMark05.

Not bothered, just curious though how comes you think i get a slightly lower overclock now? Oh and any point testing out the other bios' you got there on it, i.e. Saphire or the alternative PowerColor ones?

Anyways nice job you did there m8 thanks a heap :rockout:

*To lukow - if you got the r480 core then u aint gonna get 12 pipes out of it, blocked permantly atm, tho if u got the r420 i believe there is a chance of unlocking them check http://forums.techpowerup.com/showthread.php?t=4971 , read through those posts.

Have you looked at the gpu on your card? If it is not R481, then are you trying to unlock pipelines? If you are trying to unlock pipelines, post it elsewhere because I want to keep this thread on topic.

Someone else did have that happen as well. I think having it properly identified as R480 makes it use the gpu to its full potential, so it stresses the gpu more, making it heat up a little more. However, so far the performance increase seems to always at least make up for the loss in overclocks.

If you want to test out the other bioses to see how they affect max overclocks, try the modded GTO2 bios and maybe the other Powercolor bios. If you try the X800 GT Evo bios, be aware that it does increase the default clock speeds to 500/527 or something like that. I'm also posting the earlier revision bios, but modded to R480, so you can try it out if you want.

Greetings. I bought a Powercolor X800GT back in Sept. I ran across the Tul bios over at Bjorn3d, tried it but was not able to get any overclock at all. Now I find this place and lo and behold it works very well. I flashed the bios with the Powercolor.X800GT_R480_16P.256.Samsung20_050715.zi p using atiflash. It now shows up as a X800GTO with a 480 core.

My previous best I could do was around 4700 in 3D'05. I did 4992 last night with the new bios. I was also able to retain my previous overclock of 570/570. Temps were 32-33 idle, and I saw it go as high as 52 during 3D'05 but for the most part stayed in the upper 40's. I'm using a Zalman vga hsf w/ramsinks and a Zalman CPU hsf. All in all a very decent operation. I know everybody is looking for that magical unlock but it's becoming apparent to me that it's just not gonna be possible. I've looked at the posts on bridging the laser cuts and Vmods and such but I'm feeling a bit lazy and I really don't want to pull my card out at the moment but I probably will at some point.

I've got some OCZ Gold VX sticks coming today. Hopefully they'll get me over the 5000 mark on the benchmark. That's been my mission so far.

Thanks for all your head scratching and work on the bios!

I think that's the first case I've heard of someone trying it and it didn't negatively affect their max overclocks. Maybe the older bios is better to use?

BTW, I had already known from testing on my GTO2 that the performance difference changed with different numbers of pipelines, and I had guessed that the same happened with overclocking. You've shown that I was correct in saying that the performance boost for the modded bios is even greater when overclocking.

Well i tried out all those bios' there ShadowFlare but none seemed to OC as well as orginal bios, the Powercolor.X800GT_R480_16P.256.Samsung20_050715.zi p i had to underclock instead of overclock lol. Saphire one seemed to give me almost the same results as the Evo version im running now but slightly less.

BTW i was searching google and saw a post where instead of using a GTO bios they were using a x850XT, curious if this would give me any different results / better due to the drivers of the x850xt probably being quicker, even though my pipes would still be 8 (also looks better as x850xt than x800gto :p ), what u reckon? anyways i dont like to link to another oc forum but heres the info i found http://www.overclock.net/ati/28036-how-mod-your-x850-x800.html?highlight=X800GT

It requires the r480 core and the 1.6ns mem which i have on my card. I dont understand what non vivo or altered mem timings is about. I didnt want to try this on my card without some kinda advise, and yours has been excellent so far ShadowFlare :rockout:

If you just want it to show as an X850 XT, I would recommend just modding your bios to the IDs of a X850 XT card by using RaBiT 1.7. Just download a X850 XT bios (maybe a Powercolor one?) and open both bioses in RaBiT, then copy the hardware ID, subsystem ID, and vendor ID to the ones in your existing bios and save it, then flash the modded bios.

Of course, it would probably be just fine to try an X850 XT bios to see if it would get better overclocks, as long as your card can handle the default clock speeds (520/540), especially since there wouldn't possibly be any fan issues on your card ;)

Oh, by the way, if you are using the bios I labeled with Powercolor X800 GT Evo, then you are not using a GTO bios - just your own bios but modded to R480. ;) If you haven't already, look at the explanation in the first post.

[Jshrk]

great stuff, thanks m8. I changed my bios to identify as x850xt however recieved same 3dmark scores with those drivers, however when i tried the x850xt bios the oc clocks stayed the same but gave me another 60 points increase which was great. I reckon i done enough testing on it now in bios modding, ty all your help ShadowFlare :)

Btw if anyone does know any volt mods or anything for the x800gt r480 core plse letme know ;).

[ShadowdogKGB]

I'm in the process of acquiring a multimeter. From what I can tell this X800GT pcb is similar to the X800/850. Another thing i've noticed is now my 3dmark results says i'm using non approved drivers. dunno.

Hey! I just burned my card!!! not sure why

I bough This
http://www.powercolor.com/global/main_product_detail.asp?id=79
Powercolor

Altough the cooler is similar to the 16pipe version!

The Chip was a 430 one & samsung 20ns with stock 400/350 speeds
I flashed with the powercolor X800GT R480 16 samsung20
& after rebooting ihad severe corruption & was unable to boot!

well had got to test it for a day & a half :(
hopefully in 3 or 4 days i'll have a new one! but unless i understand what happened i won't be tryibg it again!
I was reading a review after this hapenned on the powercolor X800GTO with 16 pipes.
http://www.vr-zone.com/index.php?i=3046&s=3
& this card also has a 430 core!

Could it have been the core or the higher speeds of the bios that nuked my card? or just incopability generally???

??? So your card is an X800 GTO, not GT? Only their X800 GT is guaranteed to have an R480 chip (Powercolor said they would only use R480 on that card). I haven't heard of a similar statement for the Powercolor X800 GTO.

Anyway, with a X800 GTO the chip is what it says it is. If the computer says it is R430, it is R430. If it says R423, it is R423. If it is R480, it will say R480. Any of those are allowed for the hardware ID on the GTO cards, so it will not ever be misrepresented, unlike the GT.

R430 chips usually can't reach the 472 MHz clock speed needed for a GT (usually not even close), so besides identifying the chip as the wrong type, the bios you flashed on your card is overclocking the GPU to a speed beyond what is generally even possible with that chip.

There are instructions somewhere about how to recover from a bad flash, but I'm not sure where. You can either search for it, or post a new topic asking about how to do it.


BTW, just to let you know, this topic is ONLY for X800 GT cards. More specifically, all the ones from Powercolor and certain ones from HIS and GECUBE.

[jeanmi75]

hello,
no solution for my his x800gt ?

thanks

[bourne]

Hello there Shadow, this is interesting, I have the PowerColor X800GT 256MB 256Bit with ATI tool stating i have the R423 Core, but very likely i have the 480 core so as soon as I get my Zalman VF700-CU and replace the stock cooling I will definately try ur modded BIOS for Powercolor.

With the current BIOS i get these max settings: Max Core 590 and Max Mem 614. So when I flash my card with ur modded BIOS i will let u know of any difference. As for Benchmarking, I doubt i'm gonna be doing that, but maybe I will who knows. Anyways Great Post, with a lot of Information! Good job.

[Silver-Arrow]

Hey Shadow,

I have the Sapphire X800 GTO2 VIVO version. ATITool detects it as an R430 core but I can overclock this card to X850XT PE speeds (540/590). A lot of people say the VIVO version of the GTO2 does in fact have an R480 but is using a different bios. Will I get any performance benefits if I flash it with an R480 bios? Which bios can I use to do this?

[bourne]

Well i got my Zalman VF700-Cu, and with this new VGA cooler i can already see an improvement as far as how far my Max Core/Mem settings go.

With the stock cooling I used to get Max Core:590 and Max Mem:612.
And now with the new cooler alone my Max Core went to 596 and my Max Mem went to 618.

Now i'm wondering how much more my Max Settings will go up once i flash my card with the modded BIOS. (By the way, i did find out that my core is in fact an R480 and that my Memory is Samsung 2.0ns).

So as soon as i flash my card with the modded BIOS provided by shadow i will post any results.

Cya's

[Silver-Arrow]

Hmm, I don't understand any language other than English, but it looks like you are talking about a HIS X800 GT with a R480 chip and 2 ns memory. Is that correct? If I'm correct in what I thought you were saying and your card is not the one with the large heatsink/fan, then post your bios, please. If it is the HIS X800 GT with the large heatsink/fan, you could use the modded HIS bios I posted.
