can overclock be cause of freezing computer?

[cherev]

Hi,

About twice a week completely randomly (can occur during gaming, but also when browsing) my computer will freeze with a buzzing sound and only a hardware reset is possible.

My temps are always good at the time of the crash.

I think its my external hdd driver because the eventviewer says somehthing about driver/wufdr giving an error.

My q: can an overlock freeze a system even though temps are good?

Cheers,

P.S. overclock was stable during IBT and Prime95 stress testing

An overclock absolutely can freeze your PC for no reason, it did that to me multiple times when I was tweaking my overclock for my GPU just today and my temperatures never exceed 65-70 degrees. What did you overclock? Your overclock isn't stable.

Hey,

I overclocked an fx8320 on a m5a99fx pro r2, by bumping the multiplier to 20 and leaving vcore on auto. Im a self confessed oc noob... I got it from 3.5 to 4 ghz that way.

Thing is, I can game for hours on end and it never freezes. Then the following it will freeze when I game for 10 mins, and no more for the rest of that day (or that week).

Temps are always good, vcore is always around 1.24. I did 20 cycles of IBT at very high and 12 hours of prime95 blend and got no freeze or anything

Cheers,
