Get your X1950Pro modded BIOS here

[Ketxxx]

Notice: Neither me or TPU are accountable for you screwing your card up attempting to use any BIOS found here-in.

Ok as some of you know I'm getting a X1950Pro shortly, so in the meantime I figured I would grab some 1950 BIOS' an mess with em a little, this is the first attempt at modding a 1950Pro BIOS so changes arent staggering, this BIOS is meant for 512MB 1950Pro cards.

Changes:

Default VGPU vcore changed from 1.3v to 1.4v
Default VGPU core frequency changed from 575MHz to 600MHz
Default memory frequency changed from 1.38GHz to 1.39GHz

Thats it for this BIOS, let me know your results :cool:

Edit: This edit is to clarify some things;

1. Latest modded BIOS is 1.7, see P54, post 1330 for download.
2. There is no promises this BIOS will work for you. Its soul purpose was to attempt soft fixes for problematic 1950Pros, as such it is NOT recommended to try any modded BIOS unless you are specifically having problems.
3. This modded BIOS more than likely won't work with all cards due to PCB revisions and differing components, such as memory.
4. 1.7 has been tested with Xpertvision and C3D cards, however take heed of point (3)
5. There is NO surefire way to get a 1950Pro that allows voltage changes via BIOS, its down to pure luck. There doesn't seem to be any one manufacturer where odds are noticably improved, either. I have only heard of and been told about success stories.
6. 1.7 is available in VIVO and non-VIVO flavours, 256MB and 512MB. I have no means of testing 256MB versions without somebody donating a 256MB Pro for testing, so don't bug me if the 256MB version doesn't work for you. See page 56, post 1389 for downloads.
7. As of yet, there is no AGP 1950Pro BIOS, and even when there is, I'll have no means of testing it.

[TUngsten]

is there a link?

the HIS x1950pro I have runs 621/1485 out of the box, might be interesting to try that bios on your card, but it's 256mb ram vs your 512

[Ketxxx]

Here she is, all done and double checked, it all *seems* to be ok. I'll do a 256MB BIOS if I can for ya tungsten ;) gimme 20mins or so.

[Ketxxx]

Ta-da! was easier than I thought, heres the 256MB version.

My X1950Pro is faster at stock clock than your clocks in the bios:p

[Lazzer408]

Did you change the fan speeds? I'd like to see 100% by 70c. My memory worked out stable at 1400. Can you add v+ to ram?

[Ketxxx]

My X1950Pro is faster at stock clock than your clocks in the bios:p

Nobody has played or even come out with decent software OC tools, I'm making BIOSes that are generic - aka basing the BIOS clock frequencies on reference frequencies (575\1.38GHz) and providing a small boost in performance over reference frequencies while trying to make sure nobodys card dies where it cant handle the frequencies - more advanced BIOS' will come later.

[Ketxxx]

Did you change the fan speeds? I'd like to see 100% by 70c. My memory worked out stable at 1400. Can you add v+ to ram?

No, I can have a look at that, for now just see how the modded BIOS does :p

[Zubasa]

I can get the memory to 790Mhz (DDR3 1580) and core to 621Mhz on CCC and it runs solid stable.
I guess I need to see how much better will it OC with the increased voltages.

[Ketxxx]

BIOS' updated.

Changes:

Fan should rev up to 100% once the VGPU hits 70c, anything below that the fan should spin @ 64%

[TUngsten]

Does ATItool report correct gpu temps on the x1950pro? I can't recall if I read that in one of the posts or something.

Mine idles ~40C and tops out under load @50C w/ the fan @60%

So Ket - what advantage would I get flashing to that bios when my stock speeds are higher?

[Ketxxx]

Better OC potential because of the higher VGPU vcore. I can customise BIOS' much more (higher core frequencies & memory frequencies) once I know these bases are working.

[s4fun]

Sorry for such an oddball request. I have a HIS Iceq3 x1950 pro factory overclocked at 620.1480. I was wondering if there is bios I can use that sets it to the ATI reference standard at 575/1380? I am trying to chase down some stability problems.

Thanks.

[mullered07]

if its unstable at those clocks and sure its down to the factory oc rma it dont underclock it to run normally, factory oc cards should be sfae and tested at the speeds theyve been set too maybe you just got a bad one ?

[Makaveli]

I just bought the Sapphire 512mb card, so i'm interested in what your going to be doing with the bios. My card already comes with the memory at 700mhz, but I do like the 600 default core speed with your bios, i'm at 580 stock. I'm still on the stock cooler so no overclocking until its replaced.

can u make a 600/725 / or a 650/750 possibly. or even a 600/700 to keep it modest.

[Ketxxx]

Indeed I can, I expect reports on how the BIOS fairs tho :p I cant start whacking frequencies up until I know the "base" is stable.

Your BIOS sir;

[Lazzer408]

BIOS' updated.

Changes:

Fan should rev up to 100% once the VGPU hits 70c, anything below that the fan should spin @ 64%

:toast:

This is the best way to o/c crossfire because CCC is needed to enable xf then atitools is needed to set each clock seperatly then save the profile and load it every time u start windows. :rolleyes: What program do you used for flashing the bios to the card and what recovery options are there?

[dolf]

Guys if you want a flash tool (on bootable CD) just prepare for me a set of moded BIOSes (1,2,3....) with short description (core, memory speed, changed Vcore ....) and I can put all together in one automated flash utility (also the original BIOS should be included).

Man I can't wait for that... I used your flashing utility to get my x800GTO up to 16 pipes without a hitch, so when Ketxx makes a bios with a decent OC on it I'll be sure to dl it :P

edit: I still can't believe that so few programs support OC'ing of the x1950 pro... it kind of makes me regret buying the card in the first place :|

[tkpenalty]

Um... Anticlutch, its just that W1zzard is taking a while to figure out the X1950PRO.

Ketxxx, can you just make a 100% fan speed operation bios? I've got the accelerox2.

Yeah I know W1zzard is taking a while, but I would have expected ATI Tray tools to OC my card a bit (it does OC the core, but as soon as the mem speed is raised, the card locks up).

Eh, it's all good. Waiting for an OC program isn't that bad especially since the x1950pro performs pretty well at its stock speeds :P

[tkpenalty]

Waiting for 100% fan speed bios T_T.

BIOS' now have fan spinning @ 100% (or rather, it should do)

Flash guide:

BIOS Flashing

How To Flash Radeon Based Cards

To flash a Radeon based card you will need to download Flashrom v2.4 Do NOT use ATI flash.

Windows XP users: Go to "My Computer" right-click your A:\ drive and select "Format" and check the box saying "create MS-DOS bootdisk"

Windows 9x \ ME users: Once you have downloaded Flashrom put a floppy in and from MS-DOS prompt at the C:\WINDOWS> prompt type; FORMAT A: /S hit enter when prompted, once the format and copy of the system files have been completed (hence the /S switch) double-click the .zip file and open the file onto drive A:\

Note: Due to MS-DOS filename limits make sure the VC BIOS filename is no longer than 8 characters long, these 8 characters do not include the file extension name (eg: .ROM)

Make sure your required VC BIOS is also on the floppy then restart the system with the floppy in the drive.

To see a full list of Flashrom commands after the floppy has loaded type; FLASHROM.EXE you will be required to hit enter once the first page is displayed in order to see the continued commands for various actions. The only commands however you need to know are as follows; After the floppy has loaded within MS-DOS, simply type; FLASHROM -p 0 WhateverTheFilenameIs.rom \ bin


That will immediately flash your VC BIOS without backing up your original VC BIOS. I however strongly advise you do make a copy of your original VC BIOS. To do this after the floppy has loaded from within MS-DOS type; FLASHROM -s 0 original.rom that will make a backup of your original VC BIOS and save it to the floppy as original.rom

Should your VC not like the BIOS you have just flashed it with you will need a PCI videocard. Simply put the PCI VC in and connect your monitor cable to it. If your mainboard BIOS is configured to display PCIE and not PCI graphics you will need to clear your CMOS, this is done either by removing the battery from the mainboard or via a jumper setting on the mainboard, consult your mainboard manual for specific details on which method applies to you.

Once your PCI display is up and you are back within MS-DOS at A:\ prompt type; FLASHROM -p 0 original.rom that will then re-flash your PCIE VC with its original BIOS. Once its re-flashed simply reset the system, enter your mainboard BIOS and set it to display PCIE graphics before removing the PCI display card.


How To Flash nVidia Based cards

To flash nVidia based cards you will need a program called WFFLASH.

Follow the same procedure as with the ATI cards. Once everything is copied to the floppy and you are within MS-DOS type the following command at A:\ prompt; WFFLASH nm WhateverTheFilenameIs.rom \ bin - flashes VC with new BIOS and makes a backup of old BIOS to floppy with filename of saveold.rom. Should your nVidia card not like the new BIOS simply follow the same procedure as for ATi cards to recover your VC but type WFFLASH nm saveold.rom

No excuses now, I want some reports :p Once I know the BIOS is good I'll start changing frequencies.

[Ketxxx]

so whos tried em? in total there have been 34 downloads, so methinks that means at least 10 of you out there have a copy of these BIOS', so I want to know if the bases are ok before I chuck out ramped up versions! Ya'll aint gettin any until then :p

[tkpenalty]

So is there a standalone 100% fan speed bios there?

[Ketxxx]

yep, last two BIOS' I uploaded (post #23) both BIOS' have the fan spinning @ 100% constantly.

[TUngsten]

how can I extract/save my HIS x1950pro bios? I don't want to flash a new bios with lower speeds, but I'd email you my current bios for manipulation...

the "save vga bios" button in ATItool isn't operational

[Ketxxx]

If flashrom doesnt work try the latest ATIflash to save and flash your VC

[deadtorights]

Will this work with a Sapphire X1950 pro Pcie 256 mb?
Once u flash it, is it possible to revert to the old bios? So i can back up it incase something screw up? And is somethinggoes wrong and i can't return the vid card, does that void the warranty?

[Ketxxx]

Check page one toward the bottom, theres a post detailing how to flash and backup your vidcard BIOS. The BIOS will work for your card, just make sure u download the file for the 256mb version and not the 512mb version. As for warrenty, technically it does void it through flashing however as longs you backup a copy of your current BIOS and just reflash it to the card if you ever need to, then they cant tell the difference.

[deadtorights]

Will this work under Windows VISTA or is only on Windows XP?
You also said not to flash it with ATI flash, but your other post said to do it with ATI flash...
I don't have a floopy, so i guesse I go with ATI flash? or flashrom?

[Ketxxx]

ATI flash is only to be used if flashrom doesnt work as flashrom is far better ive come to find through experience and usage. VISTA im not sure about as i dont use it, its crap.

[unsmart]

I'm getting a jetway x1950pro 256mb pci-e card, it is a non reference[ way I bought it] card without VIVO. It also seems to not use the Volterra power management chip. Do you think your mod bios would work on this or is it for ref pcbs only?
I glad there folks like you out there using you programing skills for good instead of give us all viruses :toast:, keep up the good work.

[Ketxxx]

The BIOS' are as generic as possible, but as with any VC BIOS flashing, your risk-gain ratio is around 50\50. The 1950Pro is a great card, however it does seem to have a bunch of heavy BIOS locks, hence only basic changes with the BIOS' I have uploaded. I would be very interested in recieving X1950Pro BIOS' from across the whole spectrum, especially those with X1950Pros that are clocked higher than ATI reference specification (575\1.38GHz) to see if any of the BIOS locks are removed.

[AshenSugar]

winflash105 for those who prefer to avoid floppy flashing.

it allows forced flash if needed, if u have a problem getting it to run (says its missing a file) rclick, compat mode, set for windows xp or 2000 and try it again, this is a bugg that effects server os's and some others as well.

i prefer to winflash my video bios, as it lets me test without rebooting, i just use att to cause a driver restart and bam, new changes are in effect :D

[Ketxxx]

it doesnt work for X1950 series, the .exe has been changed.

[tkpenalty]

I wonder why it gives this "Adaptor 0 not found" error

[Ketxxx]

Without looking, i'd suspect no support, try ATIflash, its not as good as flashrom, but it should work as its more updated.

Here is bios from HIS x1950pro IceQ3 Turbo 256mb, 621/745 stock speeds,for you to play with.

[Ketxxx]

cool. If u want I'll do a few basic changes to your BIOS like fan speed adjustments an attach it here. Then u can tell me if it works :D

[Ketxxx]

Well I thought I would give all you 1950Pro owners a small update, doing some sniffing around it looks like there are two frequency profiles for the 1950Pro, not so unusual. However one profile either A: does nothing, B: the code has been broken somewhere in the BIOS, rendering one of the frequency profiles useless, or C: one of the profiles acts as some sort of clocklock on the 1950 (editing the profile doesnt even increase 2D clocks). Editing the alternate frequency profile is what needs to be done to successfully OC the 1950, doing a quick edit from 575\1.38GHz to 600\1.46GHz and running 3DM05 gave an increase of 310pts or so, most of that gain is more than likely accountable to the VGPU increase as the 1950Pro certainly isnt lacking in bandwidth.

[Ketxxx]

Here is bios from HIS x1950pro IceQ3 Turbo 256mb, 621/745 stock speeds,for you to play with.

Hey oily, I took your BIOS and made some changes, feel free to try it if u want, fan spins @ 73% up to 40c and beyond that it will spin @ 100%. Clocks are slightly modded as well, VGPU is @ 640MHz and memory is @ 1.5GHz.

[Random Murderer]

ket, any chance you could mod the bios of my lowly 1600xt? ;)

[Ketxxx]

ahh ok i'll make an exception :p attach it in this thread

[Random Murderer]

ahh ok i'll make an exception :p attach it in this thread

ty!!!:respect::respect::respect::respect:
the bios is stock, im currently on stock voltage with an oc to 641/724.5, so could you bump the volts a little and put the clocks at, oh say, 675or700/750?:rockout:

[Ketxxx]

Theres no voltage mod options in your BIOS, however that doesnt mean your card cant support voltage adjustments, more than likely the voltage options have been removed from the BIOS. I could edit a BIOS with the voltage table still present in the BIOS for ya (adjusting memory latency to match the settings in your current BIOS etc), or I can just customise fan speeds\clocks on your current BIOS, your call.

i have a pci 9250 in front of me, so screw it, lets go all out, edit a bios with the voltage table in it :rockout: fan adjustments dont need to be messed with, im on an aftermarket cooler.
im gonna go get a bite, i'll check out the thread when i get back.
thanks again :)

[Ketxxx]

Ok, I'll go find a BIOS with the voltage table in it :D

[Ketxxx]

I cant find a 128MB X1600XT BIOS, so for now heres a modded version of your stock BIOS. Let me know how it goes.

Cheers,I'm off to work now but will try it tomorrow and let you know how it goes. :toast:

[Ketxxx]

Sweet :cool: for reference, every 30MHz or so on a 1950Pro gives around an extra 310pts in 3DM05.

[bobyjo]

Indeed I can, I expect reports on how the BIOS fairs tho :p I cant start whacking frequencies up until I know the "base" is stable.

Your BIOS sir;

Is this bios a 256mb bios or 512mb bios?
Sorta hard to keep up with what each is, the way everyone is asking different questions between your replys.

[bobyjo]

Will this work with a Sapphire X1950 pro Pcie 256 mb?
Once u flash it, is it possible to revert to the old bios? So i can back up it incase something screw up? And is somethinggoes wrong and i can't return the vid card, does that void the warranty?

I have this Sapphire X1950 Pro 256mb card also. Right now the performance is super. I don't know if a modded bios will help much, but I would gladly try if the performance would be good enough.

My 3dMark03 score is ::http://service.futuremark.com/compare?2k3=5204834

My 3dMark05 score is::http://service.futuremark.com/compare?3dm05=2664531

The clocks are stock, never been changed, 580 Core and 702 Memory.
I am running the XGWarCat 7.1 second edition drivers.
I would like to run exactly the same drivers and only change the bios to somewhat higher clocks.
What do ya think?
Thanks BJ

[Ketxxx]

Download atiwinflash114 from TPUs download area, make a BIOS dump from your card and attach it here, I'll take a look at it.

[Ketxxx]

New BIOS guys for 512MB 1950Pros - more advanced this one, heres a full changelist;

- Memory timings tweaked
- Fan speed changed to 86%, kicks to 100% when VGPU exceeds 40c
- Default VGPU voltage 1.425v
- Default VGPU frequency 621MHz (will be tweaked to an "average" clock after feedback)
- Default memory frequency 1.4GHz (will be tweaked once I get feedback on the tweaked BIOS mem timings)

[Alcpone]

Did you get anything with my bios? :D

[Ketxxx]

yes, rummaging through your BIOS is what made it click some X1950 Pros had a 2nd profile which (apparently) does nothing :p

796 for your mem eh? lucky git :p every OC proggy I try (atitool, ati tray tools, rivatuner, an a few others i forgot) wont let me increase my memory 1MHz, but I know it will do @ least 730, its at that now :D

No VGPU from your BIOS sadly, but if you want I can edit a BIOS where the voltage table hasnt been removed.

I used overdrive, then got them clocks and reverted to att and it kept them clocks, so I use att to govern aa 'n' stuff

Do you wreckon its safe to try that edited bios or does the overall outcome outway the risk? I suppose I could always flash back to original but dont have a 2nd gfx card to use or onboard either!

[Ketxxx]

Your BIOS had a voltage table bobby, so its now all edited :D VGPU @ 624MHz, voltage 1.4v, fan @ 86%, above 40c 100%.

Bobyjo's BIOS has a voltage table, just edited his, you *shouldnt* have any issues with it, its for a 256MB card like yours. Risks are always there, but gains are potentially huge.

True... but with the added core voltage u can add anywhere from another 50-100MHz most likely. Tempted u yet? :p

Dear Ketxxx (and everyone else!),

I have a Sapphire X1950Pro 256MB (PCI-E), and have attached the video card's bios here.

It's just for you if you want to see how it compares to bobyjo's and other Sapphires (although I would cautiously assume they all have the same bios??)

Thanks dude!

[Alcpone]

True... but with the added core voltage u can add anywhere from another 50-100MHz most likely. Tempted u yet? :p

I am tempted :D just abit wary about using my card as guinea pig lol, might see what bobyjo can get out of his clock! att will clock my gpu fine though im sure of that, if I even move the speed of the memory it just white screens and then I have to reboot!

Qimonda is part of Hynix, meaning they would have a sub-division. On the plus side the memory seems to be pretty damn good, just over 10k in 3dm05. Thats probably due to more aggressive memory timings tho.

ed- mystery solved, quimonda is Infineon. Still cant find out the memory rated speed via its prefix of -XP tho. Must be very new stuff.

Would the manufacturer not beable to tell you the correct speed?

What driver do you use? I am using the ati 6.11

[Ketxxx]

I'm using NGO 6.12. The manufacturer could tell me, but I would need to have some elaborate story at the ready as I'm not buying their product directly - it was just provided on a product that I bought. Currently I'm manipulating my vidRAM timings realtime, hopefully I can find that balance, at 750 so far. These timings despite being laxer than in most BIOS' are actually extremely aggressive for this type of memory it would seem.

[micron]

Qimonda is part of Hynix, meaning they would have a sub-division.
Infinion owns Qimonda, and Infinion is the absolute worst DRAM company you could ever buy memory from. They can barely meet the nanosecond ratings they stamp onto their chips, and they leave ZERO overclocking headroom for enthusiasts who wish to push their cards.

Back in the 9800Pro days, I recieved three cards that had Infinion memory on them, and returned them all until I got one with Samsung memory:p

No one wants a card with shitty memory.

:wtf: where do you get your info from?
infineon's new stuff is some of the best...


ket, about the 1600xt, you wont find a bios for a 128 1600xt because there's no such card. mine is 256, but theres also a 512 version.
so you could probably find a 256 bios with te voltage table intact.

[Ketxxx]

I did find a 256 x1600xt BIOS, but didnt use it because your BIOS reported 128MB, which I found very odd :\

[Random Murderer]

I did find a 256 x1600xt BIOS, but didnt use it because your BIOS reported 128MB, which I found very odd :\

are you sure it didnt report 2x 128?
cuz i know its 256, the papers say 256, the card has 256 stamped on the back, and all my software says 256....

[Ketxxx]

Yep, it read 128MB :wtf:

[Ketxxx]

Just thought I would put in that the last BIOS I added seems to work a real treat, simply increasing my VGPU to 640MHz brought in a score of 10727 in 3DM05, pretty sweet. VGPU voltage is also maxed @ 1.425v, theres no other voltage increases beyond that, at least not that work.

[unsmart]

I got my jetway x1950pro today so I dumped the bios for you to check out. It has stock clocks but thats all thats stock about it. I have a rev.2 x1900gt[ same pcb as x1950pro ref] and this jetway is not even close to it. As I thought it uses different PWM chips. I don't know if that makes the bios any different but I would think it does:confused: .
I hope it helps with your progress, good luck.

[fragfeaster777]

Hey dudes,

Alcpone, I'll be very willing to try out the modified Sapphire bios if indeed the bios I posted is the same as bobyjo's.

I've got a watercooled system here but get pretty bad overclocks, probably from the naked VRMs on my card. I've ordered the Arctic Silver VRM Heat spreader (2 weeks ago now and hasn't arrived!) and once I've attached it to the card, and with Ketxxx's VGPU increases, I'll push the card to it's limit and see what kind of performance can be achieved!

[oily_17]

Hey oily, I took your BIOS and made some changes, feel free to try it if u want, fan spins @ 73% up to 40c and beyond that it will spin @ 100%. Clocks are slightly modded as well, VGPU is @ 640MHz and memory is @ 1.5GHz.

First off,Cheers Ket for the work :toast:

Flashed bios this morning all seems fine,added 370pts in 3D Mark05.

Only one small thing att showing 634/742,pic attached,dont know what up there :wtf:

http://img.techpowerup.org/070216/Vcard.jpg

[Ketxxx]

I've been coming across the clock frequency anomaly as well, its nothing serious, I'll increase clocks slightly to compensate so it actually runs 640MHz on the VGPU. Keep your eyes peeled folks I'll be addin some vmod details.

[Ketxxx]

I got my jetway x1950pro today so I dumped the bios for you to check out. It has stock clocks but thats all thats stock about it.

Can you see if your Jetway has Qimonda memory?

[tkpenalty]

Wow... is it just me or is my C2D an oven? I think I might need to switch back to the stock intel cooler.... LOAD AT 50*C WTF?!

Apart from that. Does it work if I change the "Adapter 0" to "Adapter 1" ?

[Ketxxx]

Its not complete, but heres what I have so far;

Materials:

2B pencil
conductive pen \ paint

Before making ANY mod permanent I strongly advise you first use the 2B pencil to undo anything that the card doesnt like.

1.47v VGPU vmod:

http://img.photobucket.com/albums/v187/bizket/1.jpg

1.37v VGPU vmod:

http://img.photobucket.com/albums/v187/bizket/1-1.jpg

Safe voltages would be between 1.4-1.5v, above that things start to get dangerous(you can go up to 1.85v.. but expect your VGPU to die.. fast). Which brings me to my last note, the BIOS which I mod is not guaranteed to give anyone better OC abilities as some cards simply dont have the components on them to take advantage of the voltage table, hence the vmod pics.

No, I tried that as well. Flashrom just doesnt seem to work with X1950 cards.

Nice 1 mate, im just abit wary about screwing my card, not that I dont have any faith in ketxxx, its just he is finding little issues with the card that he needs to put right in his own time! ;)

[unsmart]

The mem is Samsung K4J52324QC - BC12 it also list numbers E5 EF8007ea A.
http://www.samsung.com/Products/Semiconductor/GraphicsMemory/GDDR3SDRAM/512Mbit/K4J52324QC/K4J52324QC.htm
From what I can tell it's 1.25ns at 1.8v.
The PWM IC's I have found are RT9232[ which I think is for the VGPU] and Nexsem NX2415[dual controller] that may run Vmem and the other IC's.
Is this bios any different from the ref pcb bios?
I'm hoping this card will handle higher Vgpu then the ref, since the PWM system is so different. I'm a little scared to have a jetway anything:ohwell: .

I thought maybe my x1900gt rev.2 bios might be of some interest or not.

[Alcpone]

Well curiosity got the better of me and I flashed to the modded bios you did for bobyjo and it went without a hitch, I have also installed NGO 6.12 drivers with att, it is giving me 621/695 @ stock, can you mod it so its got say 620/800 as I know it will do that for the mem no bother on mine! Then I can fiddle with the gpu speeds accordingly, its only the mem that wont play ball and gives me a black screen now then I have to reboot!

Cheers ketxxx

;)

[Ketxxx]

New BIOS, probably isnt many more tweaks I'll do. BIOS is for 512MB cards

V1.3 changelist;

- Fan spins @ 82%, kicks to 100% @ 70c or above
- VGPU voltage 1.45v
- VGPU frequency 640MHz (actual 641.25MHz)
- Memory frequency 730MHz
- Tweaked memory timings

If anyone wants to experiment with frequencies download WinClk. When changing memory frequency the screen may go blank, do NOT reset the system right away its just where the new frequencies are being applied.

Hey Alcpone,

Glad it all went OK with you! Those clocks look pretty sweet!

I'm going to hold out modding my bios until the headspreader arrives... with only a fan ventilating the VRMs, I don't want to try to new bioses with the increased voltage whilst having inadequate cooling for any extra heat generated (or does the increased voltage have nothing to do with the VRMs??)

I'll keep you guys in the loop anyway.

BTW KetXXX, is there anyway for us to modify the clocks for your bioses using Rabit etc? Just asking cause I'm thinking once the heatspreader arrives, I'd boot up with the default clocks and increased voltage, test for the maximum stable clocks and then apply them.

Cheers guys

It is a lovely oc, im very happy with ketxx for his time :D

FanATIc is a user on here and he reports 670/680 gpu, which is huge oc'ing, but I dont know how he managed that???

I use water cooling and RAM heatsinks, also I have a 80mm fan blowing onto the vrm so I am not too worried about temps!

:)

[bobyjo]

I am tempted :D just abit wary about using my card as guinea pig lol, might see what bobyjo can get out of his clock! att will clock my gpu fine though im sure of that, if I even move the speed of the memory it just white screens and then I have to reboot!

Well I attempted to run 3dMark03 and the software kicked out to the desktop about 1/4th way through.
An error that the screen was out of focus.
I reset everything and attempted to run that same program again and it had disabled all the components of the game stating that my hardware did not support this action.
I have installed my video drivers again as well as the 3dMark software.
Still cannot get the program to run.
At present I have flashed back to the original bios, but still cannot get the benchs to run on my equipment.
This just does not make scense to me.

Yea 3dMark03's scores were posted there in that thread. 03 & 05 was running great, the scores I posted links to are the best scores I had ever had. I don't want anyone to think I am blaming anything on this. I do not know what has happened. Right now I am back with the OEM bios and drivers have been completely been reinstalled as well as the bench program. I am about to attempt to run the bench again to see how it goes.

I may try the modded bios again, I think I would like ketxx to look into the bios again and see if there is anything that might cause anything like this.
Maybe be a bit milder, with the modded bios than the first time around.

Thats a DX issue, it happens sometimes, just reinstalling DX will fix it (or sometimes even just a simple restart). Here is your modded BIOS Alcpone :D As to the question about rabit, you can try it, but as of v2.2.1 (or previous versions) it doesnt seem to support X1950 cards properly, often detecting incorrect mem\gpu frequencies etc.

Do you wreckon I should reinstall gfx driver after I flash it or is there no need to?

[Ketxxx]

No need to, driver reinstall is only mandatory when I have to use a BIOS from a diff manufacturer cos subsystem and subvendor IDs are different manufacturer to manufacturer.

[Alcpone]

Got the right gpu speed, just abit shy on the mem speed though! :confused:

[unsmart]

just wondering if you had a chance to look at my jetway bios and if you think I could use your modded 256mb bios?
What do you guys recommend for temp monitoring ,atitools shows nothing and I swear I've seen the same heatsink on a FX5200:eek: . It looked like crap on newegg when I bought it but up close it looks like sh*t.

[AshenSugar]

No need to, driver reinstall is only mandatory when I have to use a BIOS from a diff manufacturer cos subsystem and subvendor IDs are different manufacturer to manufacturer.

subsystem id shouldnt change if the cards are the same, the vendor id in my exp on 19*0 cards are all ATI generic, even if you set a manual brand name with rabit the drivers dont change the name, unlike older drivers/cards where u could change the brand and it showed :)

[tkpenalty]

Hey ketxxx, do up this bios, but with no OCing, the VRMS do in fact get hot, I had to slam on a X300 (YOU WONT FUCKING BELIEVE THIS, MY FRIEND COULDN'T FIT IT IN HIS DELL SO HE CUT THE CONNECTOR :roll::roll:) passive heatsink on one of them, figures that they were making my GPU unstable; gay Australian climate T_T.

So with the bios 100% fan speed 27/4 plox

Cant see how anyones 1950Pro VRMs get hot.. I've monitored mine closely and their damn close to ice cool.. that said xpertvision could of lowered voltages, and while that seems possible for my memory they probably havent for the GPU judging by my current 640MHz - some +65MHz, and from what I see in reviews etc most dont make it much past 620MHz or so. with stock voltage.
I'll have the 256MB version of my last modded BIOS shortly.

[Ketxxx]

Here it is;

- Tweaked timings
- VGPU voltage 1.45v
- VGPU @ 635MHz
- Memory @ 1.45GHz
- Fan @ 80%, spins to 100% @ 70c or above

[fragfeaster777]

Hey dudes,

tkpenalty is right: The VRMs get very hot! There was a big discussion of this on the Sapphire forums, where people would try to replace the stock cooler with a better one, only to find that you needed to cool the VRMs for the card not to crash.

On my card, an overclock to 600Mhz from 580 (core) results in benchmarks failing to run and the PC rebooting.

Anyway, I tried Ketxxx's BIOS for the 256MB card, and the BIOS itself seems to work flawlessy. However, at those clocks, my PC would reboot when attempting to run any benchmarks.

Cheers!

[Ketxxx]

Can someone get a thermal image of these VRMs getting hot? or an image with a temp probe on one or something? It sounds like Sapphire messed up.

[madfury]

here you go :)

[Pinchy]

I havent really monitored my VRM temps...

BUT im with TK in the boiling heat of Australia, and with my GPU only aircooled, on stock voltages, i hit 627/797...and the only reason i didnt go higher was cus ATi overdrive doesnt support it

[Ketxxx]

try this. Nothing looked too out of the ordinary so in case the fan simply isnt spinning fast enough I changed that, it should now spin @ 80% and kick to 100% @ 70c or above. It might be worth also remount the HSF on your card in case its making poor contact.

[Pinchy]

BTW - nice job your doin Ket

[Ketxxx]

What can I say? I got bored of not being able to OC the card an stuff. Once I find a way to vmod memory I'll post that up as well. Seems like my memory has been undervolted :(

[Pinchy]

lmao! everyone is complaining that their VRMs are to hot, so Ket is gonna add more volts into it :p

BTW - does the XpertVision cooler cover the VRM's?

[Ketxxx]

No. It blows a strong current of air over them tho which is probably better as it allows for direct cooling. My stock cooler was v.good. It never went above 58c under load with VGPU @ 640MHz. I migrated my VF900 onto the 1950Pro now, never goes above 48c :D

ed- and whats wrong with adding more volts? :p

[Pinchy]

whats ambient temps like?

Nothing is wrong with adding more volts, providing it doesnt crash :p

[Ketxxx]

My ambient temps are 33c, according to ATT.

[Ketxxx]

Thats weird. Do you mean thers only a few c diff @ idle or load? @ load I would expect around 7c difference in temps, maybe a bit more.

[Ketxxx]

In case anyone has experienced ATI WinClk sometimes mysteriously having Vmem selectable on their 1950 heres an explanation about it from W1zz.

"the problem is that the bios has not been updated to not support voltage control .. sloppy ati

it expects an lm64 device with a certain register set .. but on the card an lm63 is present .. with different register mapping.

one of the registers that is writeable on the lm64 and represents a voltage is a temperature on the lm63 ..

so if winclk reads it it gets a number and interprets it as voltage. a second later the temperature changes which means the register value changes whicih means winclk thinks its another voltage now.

writing to a temperature readout register obviously isnt possible so nothing can change"

[Ketxxx]

Well doing some reading, I see why my 1950Pro doesnt have heat problems, my 1950Pro has had its power management redesigned with much better VRMs, so no heat = no fuss. Time to volt this bad boy.

[Pinchy]

i forgot whether it was OC'd or stock (was a long time ago)

ill test now

I would like to try again, but since the 3dMark benches freeze about half way through, would it be a problem to back off the clocks a bit?
Normally this would come if the settings are bit to high.

Ah yea, about that, the clocks were adjusted to as close as possible to your max, setting higher meant the frequency exceeding your max.

i'm following your spread, Ketxxx, for a couple of days, now, with interest cause i have an Asus X1950 pro. I see that nobody has post a bios of that GC, so i do... if that has some interest...?
It has the same name that Bobyjo's one, but some differences in it (compared with notepad :o ). Do you think i can use the one you modified for him, if my VC support these clocks, tested before, of course ?

You have the core set to 631 or therabouts, then the memory downclocked from 702 to 6xx.
What would be wrong if the core was OC'ed to somewhere close to 600 and leave the memory set to 702?

Haven't overclocked yet, and Ketxxx, where I am I need the fans at 100% asap. 80% won't cut it, the heat generated sometimes heats up the ambient temps. I'm still waiting for the VRM module to arrive though D=. They get hot without a heatsink ketxxx.

[Ketxxx]

I'll mod first chance I get got a very strange problem atm. Whenever I play oblivion after a certain amount of time it just goes to a black screen with the monitor light still green. So far I tried;

uninstalling, cleaning and reinstalling omega\ngo drivers
set system to stock
uninstalled and reinstalled oblivion
run a defrag
changed swapfile size
set all options to app preference
changed pcie frequency
some other stuff I cant remember
banged my head against a brick wall

Only thing that might have something to do with it is when detecting the 1950 a message about the hardware not being recognised is displayed. Anyone come across this?

[unsmart]

I came a cross a similar thing when OCing my jetway. At core speeds of around 630mh the screen will freeze for a sec and then go black after a few minutes of gaming. I get no artifacts and the monitor and system stay on. After a restart theres no error message and everything seems fine. I have no temp monitoring on my card[ that I can find] but all my past cards would artifact or shut down the system when a OC went to far. I really thought nothing of it because I figured my card would crap out at around that speed ether form overheating or lack of voltage. The fact everything stayed running and I got no error code was weird I thought. I did let it sit for a bit one time and it came back in a half desktop/game state, now that was really wierd :ohwell:

Core speeds of the X1950 Pro's are in the 580-600 area, I would say that 630 would be pushing this card way too much.
I can't get mine to run at anything over 600, much less all the way to 630.

[unsmart]

x1950pros come with stock clocks from 575 - 620 for the ones with better cooling, Most come 575 or 580. Mine came 575 and from what I read a 50mh OC is about tops for the x1950pros. Being impatient, I set the core to 530 first;) I can play the serious sam 2 demo[ my systems benched and thats the smallest high demanding demo I could find]for 20min max before it blacks out. 625 seems stable but I haven't done any real testing. What scares me is the sh*ty heat sink on this card seems almost cool when OCed and I don't have temp monitoring:mad:

[Ketxxx]

My card is stable (seemingly) with a core speed of 640MHz, no artifacting of any form and benchmarks run fine. Weirder still is that the black screen scenario happens even with my card @ stock :wtf: anyone got any ideas? got even me stumped this one atm.

Ed - heres a link (http://forums.nvidia.com/index.php?showtopic=17374) that may help, its a GAME BUG. nothing to do with hardware or drivers, its damn annoying, I was just starting to get used to HDR as well.. anyone found a fix for it? one of the oblivion unofficial patches maybe?

ED2 - heres (http://www.google.co.uk/search?q=oblivion+black+screen&ie=utf-8&oe=utf-8&rls=org.mozilla:en-GB:official&client=firefox-a) a massive google result for oblivion black screening, maybe an answer can be garnered from it.. gl folks.

Do you mean stock clocks or bios?
Do you have a different card you could swap in for a test.
It's seems like a issue with the card though. I remember on the Vrzone forums people where have black screens with higher[ above 1.40 I believe] Vgpus with the rev. x1900gt volt mod. I haven't reread the post but I think there where some ideas floating around to what the issue was. There was a lot of people using the mod on the x1950pros in the thread to so you might find something of use.

Workaround
Hit the tilde key (~) to bring up the console. Type CAL and hit enter. Hit the tilde key again. Resets the game's graphics and brings the game screen back.

Thats according to Oblivion tech support. In a nutshell I'd say their HDR implementation for oblivion sucks hard. Gonna do more reading.

ed- http://www.nvnews.net/vbulletin/showthread.php?t=66918 some folk have found a codec to be the problem, FFDshow or something, which i know i have installed, and i need it.. f|_|king bethesda.

[Pinchy]

hey just be happy its the game and not your gfx card :p

[Ketxxx]

in a way its worse being the game.. means the main reason to buy oblivion is now absolutely bloody worthless.. maybe the unofficial patch does something to fix it.

[Pinchy]

na, id rather it be the game than the GPU

If it was the GPU you would have to RMA it wasting time/effort/etc.

By the time you get the RMA'd card, there would probably be a patch to fix it anyway :p

[Ketxxx]

Oblivion has been out months - and no fix for it :p All I can try is experimenting with different ways the oblivion engine handles HDR or experiment with how ATi \ nVidia cards handle HDR, but that can cause problems such as some textures not being rendered, so I'll just stick to how oblivion handles HDR probably.

[Pinchy]

Im sure if they get enough complaints they will release a patch :p

hi guys,

i'm french so excuse me for my poor english ;)
i'm following your spread, Ketxxx, for a couple of days, now, with interest cause i have an Asus X1950 pro. I see that nobody has post a bios of that GC, so i do... if that has some interest...?
It has the same name that Bobyjo's one, but some differences in it (compared with notepad :o ). Do you think i can use the one you modified for him, if my VC support these clocks, tested before, of course ?

Hi Ketxxx I need the Asus modded bios too... if u make it please

[Ketxxx]

Well its official, bethesda and ati drivers officially suck atm. Weird black screens are inevitable with oblivion and X1950Pros it would seem, it even happens with just bloom lighting, albeit nowhere near as bad and Alt+F4 when it happens under bloom lighting seems to reset the game engine enough to bring the screen back almost instantly with no weirdness \ crashing. Start hounding ATI \ nVidia and Bethesda people.

ed - Just filled out a driver bug form with ATi and a tech support form with bethesda, I'll post their email responses when (IF) they respond.

HOLY SHIT 864mhz?! Wow X1950PROs are monster OC'ers at proper voltages!

I dont want to flash my BIOS :p

Im just gonna wait till an OC proggy comes out, cus my card runs perfect as-is :)

[bobyjo]

You have the core set to 631 or therabouts, then the memory downclocked from 702 to 6xx.
What would be wrong if the core was OC'ed to somewhere close to 600 and leave the memory set to 702?

Ketxxx::
Could you mod a bios that would reflect these speeds?
Default speed on memory is 702, all that would be needed would be to raise the core to 600 or thereabouts.
Timing and voltgage mods would be necessary, I believe anyway, in order to get these speeds to run smooth.

[unsmart]

Ketxxx do you think you could mod my jetway bios?
I just ordered a zalman VF700 :) so I think I can handle the extra volts. My stock heatsink doesn't even get hot under load, they may have used cardboard for thermal past. If you could set Vgpu to 1.425v and the core to 620mh with the ram at 680mh, also could you set the fan to 100% all the time. that would be great:respect: .
Those are my max stable OC at stock. I still get the black screen without reset in 3DM06 at core speeds over 620 so mine must be hardware related:( . I think it's the same prob they where having on Vrzone so I put some heatsinks on the Vregs but haven't been able to run any test yet.

The mem will do over 715mh but I want to keep it low at start up and set a profile for gaming. I haven't had the time to tweak it out so I would like to stick with safe clocks in bios.
I'm worried about my Vreg at 1.45v, they are burning hot to the touch when Ocing. The heatsinks should help but better safe then sorry. You can't reflash a dead card and may lose out on a RMA:( . I'll try 1.45 though, I kinda hope this card burns up on me.

I took a chance because it has a new PCB and thought it might OC better, IT DOESN'T!! It's cheaper then other x1950pros but not enough to justify the lack of features and the shi*y heatsink. With no temp monitoring,fan control or VIVO and no extras in the box this card is a loser. I couldn't find any reviews when I bought this card so if anyone is thinking about buying this card STOP. This is my review and it gets ** out of ***** just because it runs at stock and is a cheap second card for a Xfire set up.

Just has a cheap feel about it and you can get a card with VIVO and other features for around $20 more. With the mod bios it should do over 640mh so I guess it's not that bad.

Do you have the bios for the Sapphire Ultimate X1950 Pro?
What would be the possibility of flashing this bios to my card?

[Ketxxx]

Dear god the questions lol. If I miss anything ask again :p

Heres the story as it stands;

I spent all of today modifying memory timings and testing, while 3dmark05\06 ran absolutely fine @ 640\1.5GHz, oblivion artifacted and crashed within seconds of loading.. at a guess as I haven't found volt mods or reading points for non reference 1950 Pro PCBs (nor have I attempted anything with my card yet for vmods) its probably at a pathetic 1.8v vmem.. That said after timing tweaks I did get 3dmark passing with the memory @ 1.5GHz vs 1.44GHz, but oblivion was no go, major artifacting and crash. I'm going to install FEAR and max it out to see if that completely black screens like oblivion, if it does, damn card is going back for a replacement. Really dont want it to be the card, pain in the arse having to send stuff back.

I got a response from bethesda today as well, their going to look into the black screening with oblivion in detail and get back to me.

Now about the BIOS I mod. None of them promise to increase VGPU voltage, as it stands from what I can figure out and see, some 1950Pros can make use of the voltage table, and others cant. It depends on the manufacturer, Simple as that. Thats why I added some vmod pics.

Does anyone own a Jetway \ Xpertvision X1950Pro? If so post a few high quality shots of the card front and back please :D otherwise I'll upload a few pics of my card tomorrow at some stage.

As a general note; pretty much any X1950Pro BIOS will work on a X1950Pro card regardless of manufacturer, however you will have to watch out for clock differences and be sure your card can handle the clocks in the alternate BIOS. Also be aware that different manufacturers use different ID strings, so ATIwinflash WONT work if the BIOS you want to use is from a different manufacturer, however using atiflash from dos using the -f command to force the flash WILL work.

I'll do 2 last BIOS', one for 256MB cards and one for 512MB cards, I havent forgotten about your BIOS either random, I just lost the BIOS I was gonna use atm :p

Oh and also, if there is one thing the X1950Pro isnt its bandwidth limited, the card has more than enough available bandwidth even @ stock really, but as soon as you hit 1.5-1.6GHz, any minimal bandwidth bottleneck is completely gone, this card loves and needs VGPU clocks.

Im battling my way through the dungeons with ease with it set @ 1024x768 6x aa + bloom with no problems, dont know what it will be like when I get out into the open! I hope you manage to sort your tech issues out ketxxx :cool:

[Ketxxx]

If I had to hazard a guess I would say my card has been undervolted too much. Hence weird signal problems that go away when I ALt+F4, that or its a video memory refresh or codec issue, something along those lines. Probably gonna flash to a modded BIOS, as timings I cant get to work for squat in realtime with my current BIOS appear to work fine with another BIOS dump I loaded to test its timings realtime.

[Ketxxx]

Changes:

- 2D clocks changed to 500MHz \ 1.2GHz for power \ heat consumption & to prolong hardware life.
- 3D clocks 640MHz \ 1.45GHz
- VGPU voltage 1.4v
- Fan spins @ 100% 24\7
- Memory tweaks REMOVED.. for now.

These BIOS' are meant to be as generic as possible and to accomodate our OC brethren in places like Ozzy (hence adjusted 2D clocks), any cards that encounter ID mismatches when using ATIwinflash will HAVE to overwrite their v.BIOS with ATIflash from a DOS bootdisk. If the latter applies to the individual remember to rename the BIOS filename so it does not exceed the DOS filename limitation of 8 charecters.

Also attached in this post are ATIwinflash, ATIflash and ATI winClk.

Here are pics of my jetway. On the bottom of page four of this thread I listed the ID numbers of the PWM IC I found on the card. I now believe it's switched with RT9232 controlling the mem. Also I added the heatsinks to the Vregs on the front of the card, theres a cluster of three under each. With the heatsinks I no longer get the black screen at 630mh but it still locks up.

Can you see what the ID numbers are on the circled IC, I can't get the pic to in large so The numbers are a blur to me. If there the RT9232[ which they look like] you can pencil the resistor at pin 5[ feed back loop] to raise the volts, how much I don't know. You can prob around the MEM chips and Vregs and look for 1.8v-2.0 v, if your ram is stock at 600mh it's most likely 1.8v. It sucks you can't find a data sheet for your ram and get the pin outs:( .
http://img.techpowerup.org/070220/3_edited.jpg
It seems to me ATI/AMD is limiting the x1950pros through the PWM systems. I've seen three PCBs: ref[ the first batch] rev.1 [ ketxxx] and rev.2 [my Jetway and now MSI]. The ref boards and rev.2 [ at least my card] suffer from Vreg overheating that leads to blackscreen and ketxxx card has a blackscreen issue also but maybe software. We have 3 different PWM systems at least two[ maybe all 3] suffer from blackscreen at higher then stock Vgpu and clocks. This would foul the trend of laser cutting pipes and bios locks by setting the PWM to just above specs it almost eliminates any chance of a work around. The reason for this would be increased sell of higher prophet cards like x1950xt and to decease RMAs due to bad OCs. IMO this could be whats going on, it's just a logical guess not and thing proven. I have seen some good OC but very few for the number of cards out.

have you measured Vgpu with the bios mod to verify bios settings?

Hell if your getting 641mh with the Vgpu thats .05 low then mine must be .1v low to top at 620mh. I'll have to get out the multi meter and check. You may want to post on Vrzone, they are the Vmod experts and I'm sure they would like to checkout your bios mod to:)

updated: from the caps on the bottom fo the GPU I'm reading 1.3v which is a little higher then stock from what I've seen 1.25v-1.28v. The mem is at 1.8v like I thought but I think I can up it with a mod to RT9232. I'm not trying anything till I get some good cooling though, the mem already overheats past 700mh.

[Ketxxx]

As I say, my BIOS mods for voltage are only useful on cards that can support it by default, some can, some cant as far as I'm aware, thats why theres vmod pics too. I cant verify anything on my card cos it doesnt support voltage changes via software. Right now the only thing I'm interested in is v.modding my VGPU and memory :p preferably with a few quick dabs of conductive paint :D

If you want to add my 1950Pro pics on vrzone then feel free, I would do it but I'm already a member of more forums than I can remember :p

It seems to me ATI/AMD is limiting the x1950pros through the PWM systems. I've seen three PCBs: ref[ the first batch] rev.1 [ ketxxx] and rev.2 [my Jetway and now MSI]. The ref boards and rev.2 [ at least my card] suffer from Vreg overheating that leads to blackscreen and ketxxx card has a blackscreen issue also but maybe software. We have 3 different PWM systems at least two[ maybe all 3] suffer from blackscreen at higher then stock Vgpu and clocks. This would foul the trend of laser cutting pipes and bios locks by setting the PWM to just above specs it almost eliminates any chance of a work around. The reason for this would be increased sell of higher prophet cards like x1950xt and to decease RMAs due to bad OCs. IMO this could be whats going on, it's just a logical guess not and thing proven. I have seen some good OC but very few for the number of cards out.

My card doesnt suffer from overheating at all, it stays very cool. If anything my blackscreen is being caused by stagnant nvidia files lying around from my 6800GT or because my VGPU is actually undervolted, its a flat 1.2v.. nice, not even as much power as what a single AAA battery holds lol.

Well, my X1950Pro is going back unless someone can gurantee a voltmod will fix the black screen crap. I done everything, drivers, cooling, bios mods, the lot. Its pissing me off to high heaven. It especially takes the piss as none of the VRMs get that hot at all, I can put my finger on them at all times and their only warm at best.

[Random Murderer]

why dont you pencil vmod it and see if it fixes it, if it does, permanently mod that sucker with some conductive ink or paint.

[Ketxxx]

Because I think I'm missing something in the pencil process, I give some lead but for some reason VGPU still reads 1.2v :wtf:

Thats a shame ketxxx, are you only getting the black screen in oblivion? Will you get another branded X1950Pro?

Conductive ink comes off a treat with nail varnish remover cotton pads, thats what I used when I tried to vmod my D945 with my crappy asrock mobo, but suppose there is a chance of messing it up and killing it, then I suppose the pencil mod maybe the best way to try like random says.

I tried FEAR, that locked up :\ might try it once more and see what happens.

are you 100% sure you were penciling the right areas?

[Ketxxx]

Been a while since I v.modded anything but I think so

[Ketxxx]

Done yet more research, turns out the black screen problem can also be caused by;

- nForce chipset based systems, you can download a driver thats supposed to fix it HERE (http://support.ati.com/ics/support/default.asp?deptID=894)
- VBIOS needs updating, you can obtain this BIOS HERE (http://support.ati.com/ics/support/default.asp?deptID=894)
- Its also been suggested its a very bad driver bug thats yet to be fixed, catalyst 6.4s and 6.7s don't have this problem apparently.

I did a little searching and came across something that could be the cause of the black screen. It may be OCP[ over current protection] built in to the PWM controller IC .
If you can locate the other PWM IC and get the data sheets for both you maybe able to override it. I found some override mods for NV 7900 cards and some older ATIs so there is hope.
Can you get some close up pics of the areas around the PWM ICs. I will post them on Vrzone, I'm going to post my card anyway. My card just black out for the first time after the heatsinks where added so I'm looking for other culprits now:banghead:

[Ketxxx]

I'll take some pics now, to eliminate absolutely everything I even done an unconditional format. Didn't help, so anyone with an X1950Pro contemplating a format, it won't work.

[Ketxxx]

Heres the pics, hope the quality is high enough :D if not, I have super high rez versions

[Ketxxx]

Anyone that has a 1950Pro and doesnt suffer from black screens when playing games or the like, can you attach a BIOS dump from your card in this thread? :D

[unsmart]

If you could post everything printed on these two IC's and some very close up pic of those areas, it would help figure out the pin outs. I can't find the data sheet for the AT-8d. It maybe I need more ID numbers or the sheet is limited to manufacture use. If the data sheet is restricted it's going to be real hard to mod:( .

I found the data sheet for the NX2415[ PWM for vgpu on the jetway] and it does have OCP. It is controlled by a single resistor off the vref pin so should be easy to change. The only problem is there seems to be a number of checks and balances that will have to be changed also. The IC features OCP,VCP,vdroop and a external shut off. The external shut off could be triggered by anything from temps to software,bios so is a bit scary. Needless to say it's over my head:laugh:. If anyone wants to check the sheet and help me out heres the link.

Heres the pics, IC in question on the first pic is RT9214 PS8J10(<- may be an "O")R

IC on the 2nd pic is AT-8D A0(again may be an "O")6

Ive got to put it to you ketxxx, your a persistent lad and doesnt look like you like being beaten, many good tech's would have given up and rma'd by now!

Scan have the same card I have for £115 now, im sure you will find it cheaper elsewhere also. I just find it hard to believe all your problems are down to anything but the card being abit thickle!

;)

[Ketxxx]

hey cpone, do u have black screen probs with ur card? if not can u bios dump an upload it for me? :D cant find it in th
