VoltMOD Vanilla 6800

[zer0tech]

Yes. I'm trying to overclock my eVGA 6800nu to the max, and I wanted to know if anyone knew of ways to voltmod this card. Any hard or soft mods that you might know?
Thanks.

Seems to have quite a few hardware wise. I searched for 6800vmod on google.

I'm pretty sure you can raise the vGPU via a BIOS flash.

You can edit the bios voltage vids with Nbitor.

I'm using NiBiTor but after I "change" (I really don't know what I'm doing here) the voltage to 1.4V I get a yellow in the integrity reading. Anyone here knows how to use it correctly? Thanks.

i did it, using Nbitior, without any problems. 1.3v-->1.4v. i would definitely NOT recommend doing this on stock cooling though. have you used Rivatuner to unlock the masked shader and pixel pipes?

edit: i was using an older version of nbitor (this was a year and a half ago) so i'm not sure what that integrity rating thing is.

How did you modify the BIOS?
Because I restarted and it was still on 1.2V.
Thanks.

You actually flashed the card right?

You're gonna need a bootable floppy in order to do this.

 

[zer0tech]

Yeah, I did it! It is a bit more stable than before, I played FEAR for like 3 hrs. and it didn't crash.
I think is my memory which might be causing the crashes. It says something like it couldn't write on a specific location or something.
Next time it happens i'll make sure to write it and ask you guys about it.

 

[Matt2]

so you got a successfuly BIOS vGPU mod to what? 1.4v?

Let us know what the clocks are. You should get some great clocks minus the memory.

I have it set at 375Core and 375Mem. I would go higher but I'm having stability issues as it is.
I just received a message about an instruction 0x0325adc0 that could not be read at 0x00000000 or so.
Do you know what could be causing this?
Thanks.

 

[zer0tech]

OK, this is exactly what it says
"The instruction at "0x583a95bb" referenced memory at "0x033221e8". The memory could not be "read".
Is that a video card issue or something else.
