Signs of instability besides the obvious BSOD?

post #1 of 7
Thread Starter 
I'm a bit confused about the stability of my overclock. I've been running 4.5ghz at 1.32v (load) using offset on my i7 2600k for nearly 3 weeks now.
This overclock has passed IBT (100 tests at maximum), Prime95 small FFTs for 12 hours, 16 hours blend, and 9 hours large FFTs.
It's also done 12 passes of Memtest.
The overclock was stable throughout all of this and it's also fine playing games.

However, I've noticed I occasionally (like maybe once/twice per week) get random applications that don't respond or stop working.
An example that happened just a moment ago is, when I was using the search bar on the start menu, I suddenly got a "windows explorer has stopped working" error.
I've also had other programs that stop working randomly and require a restart.

I'm assuming this means that my overclock isn't entirely stable.
Either that or it's something wrong with my new SSD.

What do you guys think?

I don't think i've ever seen a machine running windows that doesn't have the occasional freeze, something stopped responding, etc. If everything has passed stability testing, everything runs cool, then I don't think there is anything to worry about with the occasional item. Unfortunately windows sometimes comes in conflict with a program, too many processes trying to access your hard drive at once, or just a poorly written program.

What is the vccio set to? I followed some guide the first time that I overclocked my i5 2500k that said that you could get away with lowering the vccio a bit and ended up seeing a bit of data corruption despite passing all of the normal stress tests. As soon as I set it back to stock volts I never had another issue.

Do you see any funny logs in event viewer?

That's Windows. My i5 2500k will run 4.5GHz at the same voltage, act the same way. Like appleg said, I have never seen a Windows machine not freeze up at least sometimes.

Haha, yeah I guess it's probably just Windows. I bumped my vcore 1 notch just in case my idle voltages were too low. My vccio has always been on default.
Thanks for the reassurance guys.

I dunno, on my 2nd rig that i host teamspeak on has vista 64 and the longest that was up was 8 months and the only reason it went down was because of a power glitch for a second or 2 although the internet its on is not as reliable and my win 7 rig on my old E8600 was left on for a few months where i never turned it off because it was downloading tv series but then i did keep them clean, running spybot, adaware and my virus thing every week or so, with the odd defrag.
The only other thing that causes bsod if ur rigs stable is corrupt drivers and usually usb ones if oc'd.
Other than that the odd lockup or freaze could be where ur so close to being stable so upping the vcore a notch as the others have stated will help but if not try drivers etc
