eVGA 8800 GTX with a modded AC3 bios

[ANP !!!]

This seems really good,
i have the Evga 8800GTX "refrence design" card

So which is the file that i will need to flash to ??

Is this the one ??

or u guys can point me to the exact file

Thx

So, this BIOS lets you change the shader clock manually? Interesting indeed!

Is the eVGA 8800GTS AC3 BIOS doing the same thing for the GTS cards???

Yes thats the correct file, but beware, you should be sure your card can do those timings and change the board type. Download a eVGA 8800 gtx bios for comparison and change the board type accordingly

For the 8800 GTS the flash is also possible. But change the board type with NiBiTor ! And be sure your 8800 gts card can do the AC3 card specs

Wht exactly is this Board-Type

Wht exactly is this Board-Type

If you open a bios file with NiBiTor you will see a value "board type" wich is something like 27AB, this must be the same as your original card !

does the flashed 8800 show up as an 8800 asc3 afterwards? =p

and has anyone done this from a cd by chance =/

i think that he means the brand by that. dfi,abit..etc

[nordien]

There is a value called board type. For example : 27AB in my case. If you want to flash a AC3 bios the board type will be 27HA(example). When you flash the card it will show up like a AC3 card, but it isn't, so to be sure the flash has the desried results the board type should remain the same.

yep seems like ur right, i must have confused nibitor to a nother program or something....

hehe just noticed this is my 666 post ... cool

[klepp1214]

so you mean if i were flashing from a regular evga 8800gtx to a evga 8800gtx asc3 bios, i woul dhave to change those numbers to match the original 8800gtx numbers or the flash would not work?

The reason I ask is it would be nice to actually have my card show up as an asc3, granted not at the expense of the flash not working correctly!

please clarify =)

If you use nvflash correctly it will work but there is a chance you f*uck up your bios/card. I would have a pci gfx backup ready. And make a backup with NiBiTor of your own bios.
There are SPD like memory timings, you dont know what will happen if you flash the AC3 bios.

might be a good idea to read this guide before you do anything:

[klepp1214]

have read the guide, just was leery on the specifics of whether or not flashing to a different cards bios makes your card show up as the different card OR thats only if you dont change the board type #'s

[klepp1214]

well for the record, i flashed and thus far it seems to be working ok. Havent been able to do much testing. I used the OP's identical settings and have his identical video card.

few things I have noticed although not sure if they are abnormal or related so far are

1) the free version of 3dmark 03 isnt showing me the clockspeed of my gpu and under type its showing a buncha weird symbols before it says nvidia 8800 etc.

2) the vista performance rating test thing is basically crashing/not finishing for me. Might just be due to my OC, looking into it as we speak.

ended up making a bootable usbkey to do the job!

I just tried the 158.19 driver. I have a new personal record:

12807 3dm06 points !

With the modded eVGA 8800 GTX AC3 bios
640/1500/2100
C2D @ 3.6 @ 9*400

[rodemannetje]

Are these 158.19 faster/better as the 158.16 or 158.18?

I think so, i had issues with the 158.18 and 97.94

Last week i downloaded nibitor @ mvktech.net. I also grabbed the latest eVGA 8800 GTX AC3 bios. After testing my normal eVGA 8800 GTX i found that it was stable @ 640/2100. So i used the AC3 bios and changed the board type to the normal GTX and changed the timings to 640/1500/2100.

Which BIOS did you download...the one that was uploaded on Feb 4th (which is Rev. 1), or the one that was uploaded on Jan. 16th (which is Rev. 2)

[Pillo-kun]

So ya saying that this one could help me to. mine card is not a super clocker it seems. 618/980 is what i can call stable and wihtout artifacts.

mabye it could go higher wit this bios if it could be flashed. hmm

[p8ntslinger676]

stupid vista isnt letting me do anything, i can run nibitor, but it doesnt show anything, and i cant run nvflash at all (yes i tried running it as administrator too so dont say thats the problem)

[Frostbyte]

Great info Nordien. I will be trying this out on mine shortly.

[Rattle]

which version of nbitor? newest ?

[phelan1777]

I saw mention of a GTS Flash, I am interested, any updates to this, or anyone have more information?

[p8ntslinger676]

which version of nbitor? newest ?

ya the newest one, version 3.4

EDIT, also just tried 3.3 and it didnt work either
