CPU not stable at 3.5ghz after BIOS flash?

post #1 of 9
Thread Starter 
Hey, i overclocked my CPU (originally a phenom ii x2 550, now a phenom ii x4 b50) and it could do 12+ hours of blend on prime 95 so i knew it was stable and then i flashed the BIOS to the newest version via the @BIOS program, rebooted, and re changed all the BIOS settings (core multiplier, core voltage, etc etc) and then it would BSOD me after a hour or so of prime 95.

right now its running at 3.4ghz, running prime95 as i type 4+ hours in. So assuming it will pass the whole night is there anything else i can try to get it back stable at 3.5? i tried raising the voltage another notch but then it will go to 70*c on/off about 30min into prime95 so i dont feel comfortable it being at its maximum for so long

i know its only .1ghz but im pretty OCD about the numbers being even haha

Revert back to the old BIOS. Never BIOS doesn't always mean better overclock.

Why did you need to update the BIOS in the first place?

Did you ever set up the dual-BIOS option on your board? You should have an old backup if you upgraded the BIOS built right in if you have set it up. Don't feel bad if you never set it up. I haven't either on my board.

After flashing, did you reload Optimized Defaults in the BIOS?
