Question RESOLVED: 6800GT: graphics corruption when back from sleep mode

I have EXACTLY the same problem mentioned in this thread:

http://www.nvnews.net/vbulletin/showthread.php?t=60167

I see that it's a common fact across many 6800GT's, even from different brands (mine is a PNY). The computer sleeps, and when it's back from sleep mode there are some 2D artifacts that are resolved with a reboot.

The poster of the aforementioned thread says it's resolved with "NV5 Rev 2", what's that? A new revision of the GPU?

Good to be back after 2 years away.

I see now that he refers to NV Silencer 5 Rev 2, which is the same model I have.

Any clues regarding the corruption on 6800GT when back from sleep mode?

Problem RESOLVED.

Downloaded GeForce 6800GT AGP BIOS 5.40.02.23.06 from:

http://www.mvktech.net/component/opt...f674ab42c1a9c8

and the NvFlash 5.50 utility from:

http://www.mvktech.net/component/opt...4d992fefbd84dd

and flashed under FreeDOS (via boot cd, safe mode option) using command:

C:\> NVFLASH -4 -5 -6 BIOSFILE.ROM

I rebooted the computer to WinXP and made it enter sleep mode (S3) and come back from sleep until I got bored.

Sometimes one has to find the way by oneself...

Uh-oh, the ambient temps barely went up and sometimes the system wouldn't boot.

I verified the BIOS I flashed the card with and noticed 2 differences from the original BIOS:

-- Voltage is 1.4V (1.3V in the original)
-- Memory config is slightly different.

I took my BIOS backup, created a 1.4V version using NIBITOR:

http://www.mvktech.net/component/opt...e969634706ca7e

and flashed the card with that BIOS mod. I turned off the case fans to make the case even hotter (to stress-test the modded BIOS). The system would boot up normally AND the graphics wouldn't get corrupted when coming back from sleep mode.

So it seems that all that was needed was 1.4V (an not a whole new BIOS).

Running a 6800gt with Vcore of v1.4v is not recommended if overclocking above 400MHz ---> this kind of extra strain on the voltage regulator components has many times proven to dramatically reduce a 6800gt's life expectancy !

Because 6800gt and 6800Ultra cards are based on same design, their corresponding bioses will allow Vcore settings up to 1.5v. However bios settings of 1.4v and 1.5v are only meant for the higher overclocked 6800Ultra card which uses dual regulators in parallel for its Vcore supply !
