It seems that some people run higher voltages with a BIOS flash.
I've searched but I haven't found anything.
Is the procedure the same as with a 7800GT?
thanks

I saw a similair post a vrzone forums, the guy had instructions on what to do, but he was scared to do it, maybe you can test it and see if it works!
hmm I went there and I saw the hard mod

6800's allow you to increase voltages by editing the BIOS, I'm pretty sure 7800/7900's and even the new ATI cards allow you to do voltage adjustments without hardmods.
Well I used nihibitor but I don't think that I flashed succesfully.
I followed the procedure for the 7800GT bios flash.
Only the ATI X1800/X1900 allow voltage change via software.
6800GS needs hardmods.
Well I took my 6800NU to 1.4v from 1.2v, and it overclocked from 325mhz to 450mhz.
I'm suprised 6800GS doesn't allow that too, all the other 6800 models do...
BTW, BIOS is software too technically :P
This is the 7800GT PCB. nV doesn't want BIOS flashes to boost performance so much.
Are you sure?

I even googled it.

Even the 7800GT allows BIOS voltage adjustments. I also loaded up a 6800GS AGP file and it also seems to read the voltages and allow for change.
Give me your 6800GS bios file and I'll see what I can do.
EDIT: Went to Mvktech.net and seen your post and BIOS file over there. The BIOS on these are quite different, and it has a max of 1.37v which sucks.
I guess this is the only new nV card that doesn't allow BIOS voltage modding... :(
This thing should clock sky high without extra voltage anyway, what clocks are you hitting right now?
There's usually a little wiggle room up (very little, if any, actually), but it definitely does allow for voltage adjustments DOWN.
7800GTXs you could 'change' the voltage setting, but if you measured it with a voltmeter, it wouldn't do anything. In some extremely rare cases, where the GPU was undervolted at stock, it would bump the voltage up to 'stock'.
Just because you can read and change the voltage table doesn't mean you'll actually get the change in use....
I am at 490/1200 right now.
Mem is not running at max, but I don't want to push it too much.
Oh well I should be stepping up soon. Only 100 more to go. :)
The cores on those things are awesome.Quote:

My XFX stock cooled did 535/1300... Even bench's a little higher... Biosmod doesn't work, already tried it...
