Testing OC with Prime95

post #1 of 11
Thread Starter 
Currently I have my 1055T running at 4.2Ghz as seen in the photo attached. I have 3-Prime95(64bit) instances(blend, largeFFT and smallFFT running at the same time. For the last 4.5hrs everything is stable. Temps are great. No if I run IBT on its own at Max, my system will reboot. I figure if I'm running the Prime95 this way I am covering all my bases(stress memory, max heat power consumption and stress FPU). What gives with IBT and the reboot?

What are you temperatures when running IBT? IBT really pushes your temperatures more than other stress related programs. Prime95 is a slow stress program, it works very well but it usually doesn't expose instability until after the 8+ hour mark. That's why for a 24/7 overclock I always let it from for at least 12 hours.

And I've personally never heard of running three instances of Prime95 at the same time all doing different things. I may be wrong, but I would try just running Blend first for CPU stability, than Large FFTs to determine memory stability.

Have you tried any other settings other than "Max"

Yes, I am pretty sure you are not suppose to run three P95 tests concurrently. Run each test separately (that way you can identify what is causing instability). Failing any stability test means your system is instable. How instable is obviously subjective.

Temps never go over 42-43oC in IBT since I'm on water cooling. As for running more than one Prime95 at a time you create a shortcut to the exe file. Right click on it and goto properties. The put an -A, -A1, -A2, etc at the end of each target link(C:\\Users\\SoulM8\\Downloads\\p64v265\\prime9 5.exe -A). This way you can start 3 at a time or even more.

Yep. Either it fails or reboots.

And what if you run IBT at stock? Does it still happen? If not, gently increase clocks and test with IBT only

I can also run SuperPI at the same time as the Primes with no issue. Will try the IBT again.

Also, if you are running 3 different types of P95 tests at the same time, it will obviously be a crapshoot finding what caused instability (say if your PC BSOD).

Since IBT is failing/crashing and temps are good, I would suspect something CPU related is causing instability. How are you testing IBT (are you testing max memory @ 20 passes?) Perhaps increasing Vcore or CPU/NB Voltage would help.
