Minimum time for Prime95 stress test?

Go to solution Solved by Syfes,

I used to use Prime95 for testing CPU's as well, but I've long stepped away from it. The load it puts on the CPU is much higher than what you'd put on it in any normal usage situation. AIDA64 stress test is pretty good and Intel XTU does the job as well.

Hi everyone,

I was wondering, when using prime95 (small tft) to stress test a CPU, is there a minimum time to determine if your overclock is good? I know some people may say that a full 24 hours is ideal, but just the thought of leaving my pc on that long terrifies me ahaha. Is there a go to time when doing a stress test? Any help is appreciated and will help me expand my knowledge!

1 hour? i think you will see it pretty fast if your cpu is OC to much.

1 hour is probably the most I've ever gone running. If no cores fail by then is it safe to say it's a good overclock?

Personally i just use it until it doesnt get any hotter, And after that wait 20-30 minutes.

Desktop:     Core i7-9700K @ 5.1GHz all-core = ASRock Z390 Taichi Ultimate = 16GB HyperX Predator DDR4 @ 3600MHz = Asus ROG Strix 3060ti (non LHR) = Samsung 970 EVO 500GB M.2 SSD = ASUS PG279Q

 

Notebook:  Clevo P651RG-G = Core i7 6820HK = 16GB HyperX Impact DDR4 2133MHz = GTX 980M = 1080p IPS G-Sync = Samsung SM951 256GB M.2 SSD + Samsung 850 Pro 256GB SSD

I thought that's the whole point of a stress test: to put the maximum load and heat on it possible.

Why the i5 over the FX-8350?

True but Prime 95 will fry a Haswell chip if you're not careful :P
