Best OC Program

[ChaoticChaosx]

I plan on upgrading to the new intel chips in May or June. So I was wondering what is the best or mix of OC CPU tests to run for stability.

What I have installed as of now is OCCT and realbench. Are these decent enough for testing or should I get something else as well?

Prime95 has been my GoTo for years now. I find it to be the fastest way to find an unstable system.

I run Cinebench R15. If it passes that I'll run R20. If it passes that, I'll run it until it has an issue. 

 

Once there's an issue then I'll consider using prime 95 but normally just dial the overclock back a tad.

I heard prime95 was super intensive and make any cpu have unstable read. Has that been fixed?

I run R15 a few times. I'll have to get R20. I also used intelburntest once before. Is that good one?

If your CPU is not stable with Prime95 running, it's your systems fault, not P95's, in my experience. That's the point of a stress test.

Oh when I was doing my old system (before I was on LTT) some on toms hardware was saying there was bug with it making even the most stable fail.

I'll take your word for it. I'll just run them all with new the chips. Haha.

Once upon a time, Prime95 had AVX turned on by default, for maximum loading. Haswell CPU's in particular got extremely hot with AVX2, hotter than any normal desktop or gaming load. AVX is mostly used with scientific loads (Like Folding@Home). Later Intel CPU's actually down clock on AVX loads to abate this.

 

I believe now it has AVX2 disabled unless you explicitly enable it. I run it with AVX on, as I want to shakedown in the worst possible situation. If it can withstand that, then it'll be completely stable and cool in day-to-day computing.

I just found a neat article regarding P95 & AVX loading. It seems the most accurate thermal test is Small FFT's with AVX off.

True and nice article. I should test my current for fun to see how hard it does run using AVX then I can see how hot it will get when rendering since haven't done that in quite awhile.
