Thread: Prime95 and Linx stress test instructions




  1. #1

    Default Prime95 and Linx stress test instructions

    May seem like a silly question, but how exactly do you stress test with prime and linx?

    How long do you run them?

    What settings should you use?

    What pitfalls to avoid?

    I'm looking for how to ensure your PC is rock solid stable.

    linx 10runs max,good test for cpu/memory,test on high usually it will fail on the last run if cpu or qpi/vtt voltage isnt enough as for prime95 it about personal preference,some run it 24hours and longer,personally i would say 12hours,blend test tests alot of ram

    linx is a good test as its quick and gives you a good indication of stability,dont forget memtest86 for memory stability

    +1 to what wazza said.

    My 2 cent is 10-15 runs of linX at max memory is all that is needed for average user. Keep in mind you need to keep a Eye on the temps with Real Temp or coretemp.

    For max stability I recommend 20 runs linX at max memory.

    Not to start a flame war, but if stability is important to you, IBT or LinuX won't cut it.
    I've assisted in too many forum threads where a system was IBT or LinX stable, but the system would often fail when running one or more of the three different Prime95 tests.

    If my system was NOT 100% mission critical (e.g not running Folding@Home), I would be happy with each of the three Prime tests running error free for 6 - 8 hours or longer. OCCT and Orthos are similar to Prime95, and OCCT has some Linpack tests that can be run. For me, running more than 5 - 10 IBT/LinX tests is unnecessarily abusing your system.

    Click on the Prime95 Testing link in my signature for an excellent Prime95 tutorial. Once you get proficient with Prime95 you can explore some of the custom testing options to help find where a problem might be with system instability.

    That's my 3 cents on the matter.
    More questions? ask away.

    But but but I must know if there's enough vcore for everything, so maybe 3 loops... one? c'mon.

    Agreed on the vcore diagnostic value.
    Note that I said "running more than".
    I've corrected the spelling error.

    I must have missed the "more" it's the spelling that got me.

    And even after all the stresses I had my system crash. Even though I have no idea what to blame it on, could be all the sleep and wake-ups at high OC :)

    Default Re: Prime95 and Linx stress test instructions

    Some tips for running Prime95:
    You can customize all tests to run 8 to 10 minutes each to tun more tests at a given time. Usually the test will fail one of the first loops of certain FFT size.
    Blend torure can also be cutomized to use more memory, set a little less than "available" shown in TaskManager's performance tab.

    It is important to repeat each test(small, large, blend) with the same settings(per test).

    To quickly reproduce a failure, remember the FFT size that failed, run the same test with the same settings and set min and max FFT to that size.


    For IBT/LynX, if used for benching:
    Wait 5-10 minutes after starting windows untill the CPU is at complete idle(good for any benchmark in general)
    For comparison, always run the same problem/memory size.
    5 loops shuld be enough.
