Volt modding 8800gt BIOS

post #1 of 5
Thread Starter 
I was reading up on how to use NiBiTor and nvflash to edit the BIOS to give the GPU more voltage and it seemed pretty straight forward to me, so I decided to try it. I successfully flashed an edited BIOS that had the "Extra" voltage set to 1.1V in NiBiTor. I boot into Windows and check my GPU temp to see if there was an increase, which would indicate a higher voltage. Nothing. I check to see if my 8800gt overclocks any higher. Nope. Without the mod I have my card clocked at 730/1850/2000. Since 1.1V, I decided to modify the voltage table in NiBiTor to get 1.2V instead of 1.1V. Again I flash it successfully and check temps again. Still the same. Overclocking still the same. I've read that this whole 8800gt BIOS voltmodding just has a placebo effect --it doesn't do anything. I have a BFG 8800T OC 512MB (stock clocks=625/1566/1800).
Am I doing anything wrong? Or is this method of voltmodding completely bogus?
Thanks

EDIT: I was just thinking, I bought this card used, so maybe the previous owner already had the BIOS voltmodded, and 730/150/2000 is just all the higher it will go being modded. Just a thought.

Sometimes there is a max you can get to. More voltage will not help.

I'm pretty sure that the 8800GT does no more than 1.1V so flashing with 1.2V won't actually change anything; it's still going to be 1.1V as that is the max. Umm...as far as more voltage helping; it should.... at least from what I've read. lots of people have successfully OCed more after the bios volt mod. weird issue u have here
