Failed Prime95 at 8hrs 30mins.

post #1 of 26
Thread Starter 
I failed prime95 at 8 1/2 hrs. I have a 3770k Oc'd to 4.5ghz @ 1.25v. PLL overvoltage is enabled and my CPU PLL is at 1.7. My RAM is not OC'd. Any suggestions on what I can change to make it stable?

By one notch you mean 1.26? Or 1.255?

Yep, typically instability is due to voltage that is too low. If it failed at 8 hours bump it up 1 notch.

1 notch meaning increase it up as little as it will let you. try 1.255. Though if it was my comp I would bump it up 2 notches just in case.

Up your voltage a notch. I have failed at 4 hours and 16 minutes, then bump up a notch, got 18 hours and 6 mintues. Another notch, 24/7 stable all days of the week, folding for 3 months straight.

Bump it up to 1.255 or 1.26? And what about my other settings? Should I change any of those?

1.255 *should* be stable, 1.26 almost definitely will be. Leave the other settings the same.

Wouldn't have thought you would need Pll over voltage enabled for that overclock speed, but only change the CPU vcore as others have mentioned and see if you become stable.

If you start changing too many settings it can make things worse and it just makes you get headaches trying to figure out why its not working.

Just to add to what silent said, when you start changing various settings at once it makes it harder to pinpoint what causes the instability, or which setting made you stable.
