Post your 8800GT overclock pics

[xt198]

Hello guys.
I just wanna know how high can u overclock your 8800gt!

[xt198]

here is my Inno3D GeForce 8800GT 512 GDDR3 (with stock air cooler)

775/1060 :D with Artic Cooling Accelero S1 @ 32C idle, 44C load on the Asus, ATM just 740/1085 on the palit 1GB with Palit's own Zalman style cooler.

[Wile E]

So far I've only pushed my Palit to either 700/999 and 2000 Shader or 725/999 1940 shader.

She was artifacting a bit at 2000 shader, so I lowered them and bumped the core a little. Netted me about 100pts in 06.

Now, if only I could get nvflash to work right for me, I think 2000 might run a bit better. I'll play some more after I get some rest.

You having a problem with NVflash 5.57? worked fine for me.

[xt198]

my card on 1950+ shader is unrunnable :D the monitor is just turn off, and my pc is frozen and i cant do anything just reset xd

[calvary1980]

im on a stock Inno3D 8800GTS 320, it's crap (selling it) but I got it for free, when I get my 8800GTS 512 I hope to get it to 850/2000/1000 with a vGPU mod and a water block. only thing I don't like about the G92's is the crappy memory.

xt198, I have the e6750 also and a 90mm zalman on it with a 120mm fan blowing out the back. I can't seem to OC it as much as you. How did you get your's running so high? I have an Antec Sonata III case and true I have a lot of things producing heat, but I think I have decent cooloing. I have 3 raptors inside and 2 8800GTs and 1 120mm back side fan, 2 slot coolers (one of them is a 2slot cooler from thermaltake).

Any help on reducing heat and upping the cpu speed is appreciated. I have tried OCing the card, but I haven't pushed too far yet. But without the slot coolers, the small 5% OC I have done now used to lockup the PC. But now the 5% is working stable. The CPU is at 2990ghz.

[nailzer]

High overclocks are fun and all but I found on my 8000GT if the GPU clock went much over 701 performance to a drastic drop. 3DMark01 went from 40,128 at 701 to 33,355 at 712.

[Tatty_One]

Damn, have been card swapping all day, am dizzy now, maaged to get this:

[Wile E]

You having a problem with NVflash 5.57? worked fine for me.Yeah. I think maybe I'm typing the wrong command or something. I'm used to flashing ATIs. Got a bios and the command string for me?

[Tatty_One]

Yeah. I think maybe I'm typing the wrong command or something. I'm used to flashing ATIs. Got a bios and the command string for me?

Command string......................

at the A prompt...................

nvflash -4 new.rom........................enter (if "new" is the name of your bios)

[Wile E]

Thanks Tat. Will try tonight. Get any further yet?

[bud951]

Please forgive the dumb question. Is there a new bios or firmware for the XFX 8800GT 512? If so, what does it do? Hopefully the bios makes it run a bit cooler. Thanks in advance.

We're using Nibitor to edit the stock bios for more voltage, then flashing it back. I use Riva Tuner for fan control.

Thank you again Tatty. It worked. I was making it way more complicated than I needed to. :roll:

[pepsi71ocean]

Im running 722/1805/1102 (Core/Shader/Memory)witht he fan fixed at 70%. It keeps the GPU below 50C even under a decent load.

[Wile E]

Just got 750/1920/1050 out of her, and still tweaking.

Here's the screen from my 3dmark06 (15252) run for it.

For some reason, GPU-z wont detect the shader speed on my Palit.

I dont know...
How much high can u overclock your cpu is not just depends on the coolers.
I got Gigabyte GA-P35-DS3 motherboard, 4x1gb Kingmax 800mhz (on 878mhz) and a e6750 with stock cooler (intel box).
Soon ill get new rams (1066mhz kingmax) and a new cooler (Arctic-Cooling Freezer 7 PRO) to a cpu.
Now with these stuffs, i can push my cpu to 3,6Ghz but its getting hot, and it isnt very good... But i think with that new cooler and with the rams i will able to push it up to 3,9 - 4Ghz - on air cooler.
Overclocking your cpu is really depends what kind of ram u got, and first of all, how many MHZ can it handle. (1066 -> 533fsb (8x533= 4264mhz) so GOOD LUCK with it :D
Get some Corsair ram, a good motherboard, and a nice cooler

[Tatty_One]

Thank you again Tatty. It worked. I was making it way more complicated than I needed to. :roll:

No worries, I have established that it is not the reference PCB so I am a bit stumpped now, I will take it to me friend who works next door to me (electronics technician) and ask if he can find the right places to mod the card correctly for a voltmod, I dont want to risk guessing wrong!

Nice score! we just need more voltage now :cry:

[wolf]

just bought a reference XFX 8800GT today, started oc-ing and ended up with this bios on it.

http://users.tpg.com.au/b3rtrand//88oc.JPG

at that speed paired with a core 2 duo at 3.2ghz its good for ~12,500 3dmarks and 435 fps in lightsmark07...

could go higher with more volts....

im running an antec 900 with all available fans on high, e6750 at stock, gigabyte p35-ds3L, 8800gt 512mb, 2 gigz of corsair 800 mhz ram 4-4-4-12 lat. 500gb WD HD and i cant get my card to go to 742/1062 crashes during 3dmark06 and i have to hard boot. Besides OCing my cpu how do you think i could get the card that high? i have more then enough cooling (my cpu sits at 19-21C system at 22 idle 27 at load) and my gpu fan is on high with riva tuner. any suggestions?

lol. It's ok. Do you know how to flash a new bios to the card?

[Mockingbird90]

no, no clue. i updated the bios for my mobo this morning and that was a pain in the ass. i can talk hardware specs all day but actually doing it is well beyond my knowledge. guess its time to stop reading and get my hands dirty hu? if you've got aim im reaping1990, xfire username:tsarsenault

If anyone here playes Gears of War for the PC with their overclocked 8800GT 512MB please let me know. Everytime I play that game with my card overclocked, the nVidia driver freezes and then restarts itself. I manage to stay in game while it happens and then im off fighting again.

[Wile E]

whoa....
As far as modding the bios, you need Nibitor. Get it here: http://www.techpowerup.com/downloads/881/mirrors.php

Unzip and run Nibitor. Go to Tools>Read Bios>Select device and select your card.

Go to Tools>Read BIOS>Read into File.

Save the file as stock.bin

Next, in Nibitor, go to File>Open Bios... and select the file you just saved.

Now, go to the Voltages tab, and in EXACT mode, you should have 4 drop down menus. And I change all of them to 1.1V (or the highest offered).

Go to File>Save Bios.... Save your file as voltmod.rom


Now, follow the flashing guide found here: http://www.techpowerup.com/articles//overclocking/vidcard/34/10 , but download NVflash 5.57 instead, and replace the command in the guide with this: nvflash -4 voltmod.rom

Nvflash can be found here: http://www.techpowerup.com/downloads/819/mirrors.php

Try end the process called NV.....??, cant remember what it is called, its the NV driver that will show in task manager....process......I think I had a similar issue on another game sometime ago, I googled and it talked about a conflict between Rivatuner and the driver, If you dont have rivatuner......just ignore me and I'll go back to sleep! it may not work in any case for this particular game but it dont hurt to try.

EDIT: Oh, and submit your stock BIOS to the Video BIOS Collection using GPU-Z. There aren't any XFX 8800GT BIOSes in there. Otherwise I would've just modded one for you and posted it.

Hello Wolf,

I noticed you have exactly the same card as myself and I was wondering if you could give me a the first few steps to take to over clocking. I am also curious about your temperature and which program you used to achieve that o.c.

thanks

[wolf]

@ Yin, the first step i took was installing Rivatuner, what a wonderfull application. 2.06 is current and awesome.

the first thing i did in rivatuner was set the fan to direct controll 100%, and to boot with that setting, the stock cooler is decent (on an XFX at least cos we have the fan with a bigger hole and 2 more blades than early reference cards) but imo only when set to 100% constantly. its a little noisy but ive got like 8 fans anyway so who cares. not to mention id rather put up with a few more dB rather than 20 more degrees.

now ive had alot of gfx cards and o/c'ed them all pretty much so i didnt really go in small increments, the first o/c i did was bump the memory from 900mhz to 1000mhz, as i knew these chips are rated at that speed it shouldnt be a problem, and it wasnt, it ran fine.

i had read most 8800GT's can do 700mhz core, with that in mind i shot for 650 straight up, then went in 10mhz increments to 700, which ran 100% stable, i left the shaders linked to the core to get 700/1750, which works out at 702/1728 in reality, the shaders do have more headroom (to about 1830) but this card flies anyway. and in my experience with 8 series cards, the card is more stable with the shaders linked.

if your interested there is a heap of shader ocing things i can get into with ya, as ive found they make a huge impact on performance, on my 2 8600GT's (also XFX and came with zalmans on em) i got the core from 600 to 700, but the shaders went all the way up from 1310 to 1836, shooting the card from ~5000 3dmarks @ stock to ~6700, but that was an ordeal to get stable, as i said if your interested we can get more in depth.

once i had acertained that 700/1750/2000 was 100% stable i made a 1.1v bios and flashed it on, so all rivatuner has to do now is controll the fan.

my temps are roughly 44-48 idle and 58-64 load with fan at constant 100% which really isnt too bad at all for a single slot stock cooler.

so in short Yin i would say, Install Rivatuner 2.06, bump the fan speed, and then start oc-ing slowly and one thing at a time, dont shoot for 2000mem and 700 core at the same time, go one then the other, then i would highly reccommend flashing your card with a OC'ed bios, as it eliminates the card needing to be software oc'ed, and is imo more stable @ the same clocks.

just go slow, be patient, and dont shoot for unrealistic speeds, not every card will do 700 on core, and some will go further... especially with further cooling + vmods... (later....)

at any stage i can help with more rivatuner advice or bios advice, i can even make one for ya (still learn more doing it yourself). and if this was too much/too fast for you, i can dumb it down and we'll go in baby steps.

hope i have/can help m8

wolf.

ps. sorry for the long post, and the reason i thanked you is because you should never be afraid to ask for help.

[Yin]

@wolf
thats great information, I'll start OCing it when I have more time, but I don't really intend on OCing it to that high yet because i just got my card and well i don't wanna kill just quite yet just in case. Thanks for the great information.

[wolf]

no worries mate, im glad my experiences can help you. and i know what you mean about not wanting to kill it, i ended up killing both of my XFX 8600's thru inexperience in volt modding, (lucky for XFX double lifetime modder friendly warranty and no questions asked :P) mistakes which i learned alot from :P but still i wont even risk it on my 8800, not till i am sure of myself and the technique.

if theres ever anything else, dont hesitate to ask.

Dude thank you for taking the time to deal with a nubby like me, the nibitor was way over my head and scared me because of the DOS prompt window. Got it all fixed up scored a 13287 with 721gpu clock 1042 memory and 1802 shader all on stock air cooling stable, and along with all that i found that i could clock my cput (e6750) to 3.8 @ 1.5v stable and at 31 degrees Celcius idle 34-35 load, even tested it for 30 minutes with both cores at 100%! I'd post the pic but the link went dead or i didnt do it right cuz im a putz either way THANK YOU!!!!:respect:

[wolf]

bios modding for a gfx card o/c is SOOOOO the way imo, and its alot simpler than one mite think, can be done in under 10 minutes easy if youve got a floppy drive and disk.

heh thats the reason i got an XFX over evga the warranty, It makes it easier to sell as well afterwards because u can give the warranty to the next person as well

Question. What about the Vista people? I dont want to make say an XP boot disk and run all this and have it screw something up. How would a Vista user make a boot disk for this and does it require a floppy drive?

I know these are all noob questions. Bare with me. Flashing BIOS's freak me out.A floppy drive is the best way to do it. And no, using a boot disk won't effect Vista. Vista doesn't even load when you boot to one.

ok old clocks were 702/1728/1998 (effective)

new clocks are 720/1782/1944

i backed the memory clock down a little as i was getting memory feezes in driver parallel lines and test drive unlimted, and in doing that i saw the core had a little more headroom, now theres absolutly no instability whatsoever, have ran ATI tool artifact scan, games, benchies and nvidia geoforms all for over an hour easy.

[The_Real_DeaL31]

anyone have a evga 8800gt superclocked hear, whats the max oc i can get with this card

[The_Real_DeaL31]

stock is, 650 core shader 1620 mem 1900mhz

[The_Real_DeaL31]

messels i'm not sure what your saying

[Mussels]

lol thats my GT and its clocks :P

info says its bios modded too.

Dont have any screens or anything cause i cant access the PC atm, so thats the best i got :D

[The_Real_DeaL31]

very nice. is there any mods for my card

[wolf]

@ Mussels, for a core of ~750mhz, you should be able to hit a shader speed of 1700-1900mhz, i just think 1566 is low for 750 core.
the G92GT comes at 600/1500 stock so even linked together the shaders should be around 1800mhz, did you underclock them intentionally?
personally on my G92GT i lowered the memory speed just a smidge to get a higher core/shader, so the clocks are 720/1782 linked.
http://www.techpowerup.com/gpuz/v3kxr/

just thought i'd mention it cos u mite not be getting the most out of your o/c is all. my experince with shader overclocking is that they make a very decent difference in games too, so upping the shaders by ~300mhz should get you 250-500 3dmarks.

today i oc'ed the shaders on my 8600GT XXX from 1360 to 1620 and memory from 1600 to 1800 and 3dmark 06 jumped from ~5500 to ~6500, i jsut want to see you get the most from your card.

Its bios modded, and yes i unlinked them.
The ram can do about 40Mhz more, and the shaders were too fussy to test with software overclocking (it would just jump 100MHz in one go, it wouldnt let me fine tune it)

It got danged quick with that core tho :D

I just got my 8800GT and started overclocking it using nTune, heres what I got:
http://www.techpowerup.com/gpuz/dx987/

Does anyone know if nTune increases voltage to the core when using its overclocking features? I am hoping it doesnt because if not, then my overclock was achieved on stock volts and cooling :D

I am hoping it doesnt because if not, then my overclock was achieved on stock volts and cooling :DNo, the most voltage on an 8800 without a vmod is 1.1V. And as far as I know, you need to flash to even get 1.1v.

Great clocks, but can you actually at least bench at that. I can get that far if I don't actually try to run a 3d app. lol.

[Mussels]

just for reference the 756 core (and other clocks) on mine lasted 10 hours of ATI tool without artifacting, and survived my housemates 4 hour sessions of CoD4 without a hitch.

get rid of nTune, and use riva tuner. I have a evga card, an ntune does wonders for MB's and GFX cards.

[wolf]

@ mussels, the shaders are fussy because they only clock up in certain increments, luckily i found a list of said increments so that if you or anyone wishes to shader o/c the can go one by one up the list to test for stability. As far as i know, this list applies to the shaders on any nvidia 8 series card.


| 1404 | 1458 | 1512 | 1566 | 1620 | 1674 | 1728 | 1782 | 1836 | 1890 | 1944 | 1998 | 2052 | 2106 |
http://www.madshrimps.be/articles/%5BOCTB%5DGalaxy8600GEoverclocking-massman-20058.png


also here is a pic showing the user set gpu and memory frequency's vs the effective frequency (also applies to all 8 series cards i believe)

MEM
http://www.madshrimps.be/articles/%5BOCTB%5DGalaxy8600GEoverclocking-massman-20057.png


and like i said around 750 core you should be aiming for 1700-1900 on the shaders, it wont help as much as going from 600 to 750 core, but it should add 4-8% going from 1500 to 1700+ on the sp's, a worthwhile gain imo.

[Mussels]

i knew the shaders went in increments, but i found it varied a lot in software (and i ALWAYS check teh clocks in rivatuners monitoring page before flashing due to the variances)


thanks for the shaders, i'll see what i can manage.

[fitseries3]

it's nothing special, but, i thought it would be a decent addition to this topic...

EDIT: they are for sale BTW.

[Mussels]

740Mhz core is win! :D

[fitseries3]

740Mhz core is win! :D

can do 760mhz core but they aren't in my machine right now or i would do another bench. 760 is max though with the zalman coolers.

[SK-1]

I am getting an EVGA 8800GT 512MB and putting a Thermalright HR-03-GT heatsink on with a 92mm fan... how much do you reckon I'd be able to get? I don't want to push it too far... not much further than 700 clock... maybe a bit more

What do you use to overclock?

My Mobo is Gigabyte P35-DQ6

My Mobo is Gigabyte P35-DQ6700 will be a cakewalk with that cooler. Well, if you don't get a bum overclocker.

Most use RivaTuner to OC.

Cool thanks, I hope I don't get a crap overclocker... i wanted EVGA coz I know they are good and finally found a place that imports from US.... for cheaper than the local ones... don't ask how

[Mussels]

if you havent already ordered, the accelero S1 is madness. on the G92 cards.

even on the GTS, a single 80mm fan gets us 50C load temps (cs the 80-90 of the stock cooler, 30-35c ambient)

[oli_ramsay]

I can't get mine stable past this::(

http://img.techpowerup.org/080404/8800gt.jpg



It's got a great stock cooler http://www.inno3d.com/products/GRAPHIC_card/gf8/images/8600gt_wind.jpg and it doesnt go above 65C, so I dont think it's a heat issue. Do you think it's my EZCool 650w trashy PSU that's holding me back or do you think I should flash it to get a lil bit extra voltage?

I've never flashed a VGA BIOS b4 and I'm bricking it in case I do it wrong lol

P.S. Sorry 4 reviving an old thread!

[Mussels]

lol you're at GTX clocks :P

It could be power, i'd reccomend a new PSU anyway just because i dont like cheap PSU's.

Damn, have been card swapping all day, am dizzy now, maaged to get this:

Is this with a volt mod?

Is this with a volt mod?

Nope, just the 1.1V BIOS mod.........I sold that card for serious money! :D

[oli_ramsay]

I'm getting a Corsair HX620W on Monday and I'm gonna try the BIOS flash ting to get a lil bit extra voltage :)

Correct me if I'm wrong but do you:

1. Dump current VGA BIOS using ATiTool

2. Open BIOS file with NbiTor (or whatever it's called)

3. Edit BIOS file to add more voltage, higher clocks etc using the same program

4. Save new BIOS file

5. Copy new BIOS file to floppy then boot off floppy and flash from there

I'll research it a lot more over the weekend so I don't endd up with a very expensive paperweight lol

Even with central heating, 18*C Ambient inside your room wouldnt give the same temps as 18*C here without artificial heating! Did u add any fans though?

Wait, who increased their PCI-E clockspeed? Does it help?

I can't use NiBiTor to save it so I used GPUz instead. Does it matter that it saves the original BIOS as a BIN file and the new one as a ROM file?
