what do you want to do go to 1.5v? if do you can follow this and change it to 1.5v instead of 1.4..

be sure to let us know how you make out, i want to see what an ultra can do with 1.5v, probably insane

I really would not push it beyond 1.4v, I have heard that it doesn't seem to help much. Not to mention alot of GT's were suddenly failing after boosting them to 1.4v.

arent the ultras already at 1.4v though? i have my pny6800gt at 1.4v and it runs beautiful, and had a much higher stable OC.

Hi everyone

I think i altered the volts to 1.5 before i flashed it to the evga extreme edition bios, will have to check when i get home. Basically the core will go to 485 stable at the moment maxed out, and im upto 85,546 in aq3 and 29,157 in 3dmark 02, my gpu core is water cooled and the radiator/fan is mounted behind a grill on an outside wall.(its around -3c at night here at the moment and it takes my core down to 34c..... :D ). I have found some info on vcore modding with a pencil and resister, which im going to try tonight. The fastest 3dmark02 single card ultra score will be mine i tell you all mine........... :p
