PC throws occasional "WHEA corrected errors" but seems stable?

[flexy]

Info: Wife's PC, Ivy Bridge i3570k, Asus P67, MILD overclock to 4300 something, Win7, GTX 670.

I am NOT an oc newbie.

So she complains about recent crashes playing SWTOR and other things.
She had a recent infection but that is cleaned out and I checked everything with malwarebytes, autoruns etc.

I am checking event log and see a TON of WHEA *corrected* errors which otherwise would indicate some OC problem, I'd otherwise increase voltage a little.

So I am running OCCT small, medium,large...no problem. Temps are fine as well, CPU doesn't even go above 80C.

I am running any stability test I can find, Heaven Benchmark, Asus Real Bench, Prime Blend, OCCT...let them rip, no problem whatsoever.

Needless to say that my wife hardly does anything demanding on the PC, except SWTOR which barely taxes the system.

Looking at Prime, OCCT, ASUS Stability Test etc. to me the machine is stable.

Wondering whether WHEA *corrected* errors can be thrown from software or the malware she had? I haven't seen the errors now recently in the log, if it would be a h/w OC problem I am sure my stress-testing would have thrown some?

Give the CPU a touch more voltage. You're probably on the fringe of stability, with that game being the one thing that throws your rig off.

WHEA errors are pure hardware errors, AFAIK. They are generated from MCE (machine check exceptions) from an x86/x64 CPU. Your overclock isn't 100% stable.

Could the chip be starting to degrade?

I still run a 3770K@4.6. WHEA errors are what happened when it was on the edge of stability. It will seem fine when you do stress tests, but you'll occasionally see crashes or other strange behavior. you're probably .01-.03v away from it being completely stable. Even something as simple as making your LLC more aggressive might be enough to do it. Once I got to where I wasn't seeing WHEA errors, it was 100% stable.

TLDR; give it a tad more voltage.

+1 or back off the clocks 100Mhz.
