8800GT bios for better overclocking! *test*

[jason4207]

Does anyone knows what is the default VID for XFX 8800 GT "normal" alpha dog edition (600/1500/900).

My card fails 3Dmark06 above Core/shader 710/1724 (stock memory) and locks up in Crysis above 690 for the core and 1678 for the shaders
I see almost nobody having such "bad" results with their 8800GT. I know OCing depends of your luck to get a good chip but mine must be a really a cr*ppy one

Is it possible the default VID is 02 (1.05V) and thus if I flash to VID 03 (1.10V) I will improve my OC headroom ?

Also I don't have spare PCI VGA so is the chance that the flash fails high or is it like motherboard flashing ? Is there any way to restore the old BIOS without spare PCI VGA if it fails (like knowing the command to enter without seeing anything) ?
Well in that case I still could go hunting for a PCI VGA but I want to know what are my chances before to try it.

Last question, will the stock cooler be enough with modified fan speed to handle 1.1V ?

Your clocks aren't that bad compared to mine. The BIOS mod worked for me, and I think it'll work for you too. I don't have a spare PCI VGA either and had no issues. Just make sure to save a copy of the original BIOS to the same floppy as your modded BIOS. I called it "original.rom", and the new BIOS "1_1.rom".

If you by chance have a bad flash you need to have memorized (or written down) the steps it takes to do the flash so you can do it blind. I have to press F8 first to bring up the boot selection screen. I know floppy is first on the list so I have to hit "enter". Let DOS load. Type in the command "nvflash -5 -6 original.rom". Press "y". Wait. cntrl-alt-del. Voila!

I'm using the stock cooler, and it is coping just fine. I was at 70 w/ fan at 100% under ATI Tool load. I might try and play Crysis tonight and see if I can run the fan lower w/o having any issues. I played Crysis last night before I did the mod at 712/1674/929 w/ 67% fan w/o issues.
