Oc'ed at any freq causes system to reboot when idle

post #1 of 5
Thread Starter 
I run prime 95 for 12 hours and its fine and i play video games and no issues.

but when i leave my pc alone it reboots.

event manager says


Critical event 41:

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

no bsod.

no warning.


just happens when im AFK.

any ideas?

does this happen whenever you leave or just after playing or stress testing. It might be that your Vcore is slightly too low.

normally i can kick it up to 4.5GHz and its fine. i set it to 1.35V with LLC on. and there's no issues when stressing.

cpu -z shows 1.352V.

I seems like it can do 4.5GHz at 1.3V, but then i noticed the crashing so i bumped it to 1.35V.

its still happening...

Had this same problem. Had to update all drivers and in the end it had something to do with sleep mode. Now I have my monitor set up so it turns off from idle, but computer won't go into sleep mode and havent had that issue again so far anyway..... Not the most power friendly setting but atleast I'm not getting those hard shutdowns anymore.
