I've spent hours upon hours while running tests on my OC looking for definitive answers on what counts as a valid stability test and there seems to be no consensus.
There's people who swear by 24hour runs of Prime
Others will say Prime is to be avoided (especially for Haswells) and that tests like RealBench and X264 are better for showing stability
There's folk who say run Prime for an hour doing custom at 1344 FFT, others will say 10 runs in IBT on max will usually root out a dodgy OC
There's people who have said they could run Prime for 24 hours but crash running x264 and also the opposite.
So what is valid stability ?
I can run Prime on custom at 1344FFT, done 40 runs of IBT, ran x264 overnight without issue BUT I tried running the CPU:OCCT and it crashed after 10 minutes, however CPU:Linpack with AVX works flawlessly. Likewise Prime on custom with min 8FFT to max 4096FFT also yields a crash.
I'm on Haswell and I'm running close to my limit on temps, IBT, Prime, OCCT all push the limit to near 90 degrees so I'm wondering if it's more the temp causing instability than the actual voltage (even though Prime @ 1344 and IBT work fine) all the other tests don't really heat up my core and I hover anywhere from 60 to 70 depending on the test (currently running Asus Realbench bouncing from 68 to 70)
I know it probably comes down to personal opinion but if it can't run everything then surely it's not stable ? Or are we to not include the absolute extremes we find in Prime/IBT/OCCT simply because they are absolute extremes and nowhere close to realistic usage (unless you happen to enjoy using your pc to calculate extreme prime numbers) ?
