Rig is 4hrs prime stable but just gave occt a wee try as not used for a few years now and it failed within 30 seconds!!!???

Was given impression years ago that prime95 was a better/more rigorous way to test?

Dropped 100Mhz off and ok now.....been fine in games etc last few weeks since built.

Any thoughts?
 
if its running fine day to day its running fine. if it fails drop back a little and carry on.
 
Personally, I dont just rely on prime95 alone, I run multiple stability tests, IBT, prime95, AIDA64 (but the FPU test only), memtest.

However if you were prime stable, then I would have just bumped up the vcore a touch rather than backed off on the mhz.

Thats all very well for some but i need it rock solid when under stress no matter what :)
oc isnt any good unless its properly stable in my books.

all good now at 100Mhz less so will stick with that for now...killed a cpu with too much vcore before and at 1.38v already so thats my limit :)

(for now at least lol )

cheers
 
Try running OCCT with the overclock removed, it could just be buggy.

Which Prime95 test are you running? small and large fft are the best ones for CPU testing, blend is more of a memory test.
 
when o/c'ing an old i5 2500k to 4.8ghz I could run through prime without issues but the moment I tried intel burn test it crashed.

Got it stable in ibt and tried skyrim and then it crashed again.

I think no single test is all conclusive. You're better off doing initial testing in prime/ibt/occt then using the rigorous everyday applications you need to run to confirm your clocks
