Posted June 19, 2019 Hi guys.. I always use Realbench and Aida64 to stress test my CPU they mostly completed the stress test to show me that my system is stable. Lately I installed Prime95, when I 1st time run stress test on it, instant BSOD Whea_Uncorrectable_Errors, 2nd try same, 3rd try same even I disable my CPU OC and turn off the turbo boost. Stock 3.7GHz still BSOD only with Prime95, with Realbench and Aida64 not even single BSOD. Could someone point me out what happen here?

Posted June 19, 2019 I usually use Intel Burn Test (Maximum level at 10 passes) myself and haven't really tried prime95 too much. It does get to the point where you're just pushing over extreme loads. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

They're both basically the same, you don't need to run any power virus/burn in tests to test an overclock.

Well, you need to up the voltage for these extreme tests (Intel Burn Test as well). They push the CPU to crazy loads. I haven't had any issues with the builds that I've done that have survived Intel Burn Test. But yeah, if you're just gaming, I wouldn't try any crazy tests.

Posted June 19, 2019 If it crashes just doing math work in Prime95 then it's not stable. If it crashes running the stress tests then you're still not stable but closer to being stable. Are you running, smallest, small, blend, or which set? if it's crashing on small then it's a CPU problem, if it's crashing on blend or large then it's more likely a RAM issue. Temperature can also cause instability if you're on the edge of stability, and Prime95 small fft gets things very very hot compared to any other CPU stability test I've ever used. I always go to Prime95 first and make it stable there then run other tools like realbench to verify stability. How are your temps? Have you tried to increase voltage to the CPU or adjusting the RAM speed, voltage, or timings depending on which it's crashing for? Give some more detailed info and I think we can get your system to be actually stable not just 'good enough'. Crashing at stock speeds likely means the voltage is too low or some associated voltage is too low for the CPU to operate properly when at real 100% load, again assuming this is the small fft testing. Perfect example I recently had. I have an undervolted CPU that was stable at -0.145 offset. It ran Prime95 in all the different stress test modes for 24 hours each without a crash of any kind, it ran realbench for several 8 hour sessions without a crash. I changed the CPU cooler. It crashed in Prime95 small fft. Repeatedly would crash, sometimes soon sometimes after hours but it would crash. The ONLY change was the CPU cooler that was smaller and the CPU ran about 20C warmer, peaking out at near 70C instead of 50C. As temps rose how the CPU worked with that -0.145 offset changed and it became unstable. Adding back 0.005 volts made it stable again. Maybe I'm on the fringe here but when I say something is stable I mean it's stable as close to 100% as I can make it, even if it means I don't hit speeds that others say are stable. Data loss, crashing during a game, etc are just not acceptable to me. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Auto LLC, if that's set to 2.1 mOhms, and assuming prime95 is pulling 100 amps on your system is: 1100 - (2.1 * 100) = 890mv = 0.890v. Even if it's using the mOhms value for default loadline for 8 core processors (1.6. mOhms) is still going to be 1100 - (1.6 * 100)=0.940v. Trying to run prime95 at 0.890v or 0.940v and complaining that it's crashing? Good luck man. (Then again I have no idea what mOhms setting MSI uses for its "Auto" LLC. Gigabyte uses the same value for Auto/Normal/Standard (1.6 mOhms for 8 core processors, 2.1 mOhms for 4 and 6 core CFL, but it's possible other programs or Multi Core Enhancement can change the LLC if it's set to auto) Please do what I said instead of making excuses first. Other software doesn't pull the same amps as prime95. I'm 99.95% sure if you downloaded OCCT 5.0.1 and ran the 90% linpack test, you would get an error after awhile.

If you watch the CPU package TDP when running other tests and running Prime95 you can see a big difference in how much work the CPU is actually doing.
