Looking for a stable E8400 volt setting for 3.6

post #1 of 8
Thread Starter 
I have an EVGA 750i FTW board and I leave the volt settings on auto. When I adjust the FSB to 1600 (400X9) my BIOS CPU Core is 1.35000v and CPU FSB is 1.30v any suggestions?

Yeah, you don't wanna use auto with vcore. You never know what it'll shove at the CPU. Start with 1.22 or so. See if you can post and get into Windows. Then go up a little each time.
That should boot 3.6Ghz easily at 1.3v or less. I get 3.6Ghz with stock volts 1.225v. But each chip is different. But you should reach that in less than 1.3v easily.

Looks like CPU core will bump up your CPU voltage on that board. Set it to 1.3. Also try bumping up that FSB to about to about 1.3 for starters and make sure to manually set the voltage for your RAM( whatever it's rated to be)

for 3.6 i think i needed to set mine to 1.25v in bios for 100% stability.

edit

set them back to what they were on auto and see how high you can push your fsb
