Which torture test mode do you guys usually use when testing system stability? The default "Blend" mode? I had my new machine running "the first" test for 8 hours without problems, and really thought it was stable. But I let it go, and after 15 hours, I got an error and it halted. I didn't know stability issues would show up after such a long time Also, another funny thing is that my old computer, which I'm upgrading from, halted after just a few minutes.

Despite this, it has been running games and other programs perfectly for about a year now. Electromigration seems like a likely culprit meaning time is a key factor. Note that while this article is regarding Haswell-E, the same logic really applies to Broadwell-E as well as Ryzen 5 and 7. Running a processor at triple its nominal TDP nonstop for a prolonged period with most of that power going though a few specific execution units simply cannot be healthy for it.

This is a slippery slope towards CPUs which are only warranted to run certain approved apps. Besides, Prime95 isn't what I'd consider a pathological case anyway FFTs are common in scientific computing and signal processing, and having a CPU continuously perform them is not at all an unusual workload.

I agree with you, but with the caveat that CPUs should be able to run flat-out, indefinitely at rated voltage. The way I see it is an over clock is only stable if it can run the same applications as a stock clocked chip could at full bore for the same time periods. So if you could take a stock k or something and run prime95 small FFTs albeit at 90C for 24 hours with no issues then your OC should as well.

Having a high standard like that means I have more confidence in my OCs and my systems. Given how much power AVX consumes I wouldn't be surprised if throttling it even let you clock the rest of the core higher. I doubt many CPUs are suddenly erroring out for the first time at 23 hours. So why not just test for an hour and call it good? An hour of super abnormally high stress is more than enough to validate it for standard usage in my opinion.

More than OK at 30 minutes too. Thread Tools. All times are UTC. The time now is Sat Nov 13 UTC up days, , 0 users, load averages: 0. This forum has received and complied with 0 zero government requests for information. A copy of the license is included in the FAQ.

A longer test to detect possible overclocking-related instability makes more sense this way, even if we think you should still run a round of benchmarks using real-world workloads. As before, using Blend instead of Small FFTs increases the memory load while easing up on the execution cores somewhat.

Knowing when to pick this combination of settings is difficult, since it's perhaps the least-taxing of all. We consider it well-suited to systems without the best cooling, such as laptops and mini PCs. Topics Components. See all comments 9. Is this like a fancy water cooler im guessing? In fact i have a skyth fuma but may save up to get some kind of AIO water cooling been tryin to find decent reviews on decent water coolers both cheap and if needed high end.

This is a high-end compressor cooler for up to watts heat input. It's a modified version from industry and mostly used to cool the head of powerful laser cutters. Why I'm using this one? To show, which program is able to do it right.
