Prime95 Stability

post #1 of 11
Thread Starter 
I know many people will have different answers but what is a good time to let prime95 run (blend) and know that your CPU OC is stable. For example if the answer was 5 and you let it keep running and you got bsod at the 8th hour does that then mean that it still is unstable or?

im pretty sure its not supposed to blue screen at all... i think a 10 hr blend will determine whether ur stable or not.

if you dont want to run it for 12 hours then use 20 or so IBT runs.
plus IBT is a higher stress test then Prime.

For some reason, the sig rig was stable at IBT(maximum, 4 threads) but can't even finish a single pass in P95.

I'd say if you pass 12 hours of Prime95 without any errors at all, consider it rock stable. But first you need to decide the highest OC you want and then run IBT for short tests and once it passes, then switch to Prime95 for the final 12 hour testing. You might need to bump your vcore and expect a BSOD upon switching to P95.

It's worth the wait of 12 hours straight. You won't be looking back to your bios once your rig passed this test.

I do 20 IBT runs then a 24h Prime run with 90% ram, that is what I consider stable. Just two days ago I passed IBT 20 mins and failed prime 22 hours in @1.315 :/ but I passed yesterday both tests at 1.320. Good luck

Same for me, at 3.6GHz I can do 50 runs of IBT no sweat, but will fail after 10 minutes of blend in P95. At 3.5GHz my 24/7 OC I am 100% P95 stable

Run 12hrs and I'd say it's good. Then you can submit to the Sandy Stable Club. I ran 15hrs on my run.

I go the extremely excessive route and shoot for 24 hours in blend. I've had workers stop 15 hours in before and I don't like to take any chances with instability. Having said that, you're probably fine with 10 hours or so.

im running p95 at the moment on large ftts.
I only want to make sure my temps are ok rather then stable.
Currently running 4.5 @ 1.25v. CPU-Z is showing 1.232.
Now i forgot to check if LLC setting in BIOS but I dont think that will be much of a issue at these volts.
