Just volt modded my 7800gt

post #1 of 43
Thread Starter 
Finally found some diskettes and got around to flashing the BIOS for the 1.5v mod.

Went into coobits...

before BIOS volt mod optimal frequencies were 430/1050

after BIOS volt mode optimal frequencies were 502/1220

I'll run some benches when I get home.

thats not gonna work. You can't flash any of the G70 card. Your voltage might say 1.5 in bio but its still gonna be 1.4v hard wire in your card.

Ati cards can change voltage with software, but Nvidia cards can't. If you want to change the voltage, you're going to have to hard mod it. Your BIOS flash will, however, change the reported voltage. (it'll state 1.5 volts, but it won't actually change the voltage on the card)
Edit: Lol, the above poster beat me to it =P

What about 6800 series cards (NU,GS,GT,Ultra), can they be voltage modded through GPU bios?

Its my understanding that a bios flash CAN change the actual voltage to nvidia cards, just not any of the 7xxx series, only 6xxx series and older...

So I guess these are false...
