Overclock how long to run prime95

You won't be able to use your computer while Priority 10 Prime95 Torture Test is running, but it'll confirm your system stability. Wow, Thank you!

All I need to know! Cya, SliNGky. I have a silly question, once Prime95 is running in priority 10, it still shows low priority in the system task manager so I right click on the base priority and set it to HIGH, and is this another way to tell prime95 to die quickier if the system is not stable yet?

It's an internal Prime95 setting, forget about using the computer with that setting set to 10, people usualy use it for overnight testing to confirm the stability of their systems They usually run it hours Open the pod bay doors, Cortana.

It always breaks stuff and generates business for me. The blend test doesn't test the cpu nearly as much as it does on Small FFTs. Core i3 3. Thanks for your input. Blend always clugged up my system, even on low priority rendering almost unusable, running Small FFTs has always gave me higher temps and never failed me.

Blend does a great job of testing memory though, which for XP and P4 systems would include testing the northbridge chipset, good for overclocked FSB's. I went back to my initial settings and have been happy ever since.

Don't believe the hype!!! The only way to stress test your system is by running your system in YOUR normal capacity. Darkbreeze Retired Mod. Jun 24, 69, 4, , 8, Just wanted to add something to this thread even though it's fairly old. There is a point that is rarely pointed out on any forum threads related to stress testing with Prime95 to verify stability of overclocks.

There are many other factors that can cause a system to crash including driver issues, memory issues Unrelated to overclocked RAM, just to clarify , hardware faults not caused by voltage and problems within an applications code or the kernel itself in some cases.

Even a poor quality PSU can and does cause similar errors when voltages are not clean and delivered in the expected and necessary amounts. So just because you get a bsod or your system crashes at some point after setting up an otherwise unremarkable overclock, does not mean in and of itself that the overclock is unstable or that you failed to run Prime long enough. That being said, running it for only a short time or a couple of hours does not allow it to run through all the FFT lengths which is the REAL reason it was originally recommended to run it for 24 hrs.

Usually Prime95 will detect an error within a matter of minutes if an overclock is not stable, however many people like to let the system "burn-in" overnight to ensure long-term stability.

FPrime95 is a small and easy to use application that allows you to find Mersenne Prime numbers. Mersenne numbers can be proved composite not prime by either finding a factor or by running a Lucas-Lehmer primality test.

Prime numbers have long fascinated amateur and professional mathematicians. An integer greater than one is called a prime number if its only divisors are one and itself. 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. Usually fails within the first 5 seconds, if you make it to 1 min then you have a very solid chance of making it the whole way.

If your data assurance requirements exceed one "proof test" shot[0], so to speak, then you have no business using overclocked CPUs at all. Prime95 SmallFFT is way way more stress than you would ever put a CPU under in any real-world load, and like an overpressured proof shot it's not really the best thing in the world for the processor to do this nonstop.

Electromigration is a thing that exists. I think it's possible with exotic cooling solutions like custom water cooling. The costs are often ludicrous and not something you'd put into a cloud server but for a home workstation a good water cooling setup can get you better than stock performance such that you could run Small FFTs for hours or days and be fine. That sounds like overkill but it's peace of mind for me and I need that or I'll just keep the thing stock which I've been doing lately.

My current v2 xeon based workstation with a lot of enterprise Sas SSDs and tons of ram is at stock because the xeon line is locked down and it's plenty fast. Wait, SmallFFT?
