prime95 hardware failure

[Jules A]

Hi,

I OC'd my CPU, which is an i5 6600k, and ran prime95 to stress and it game this error.

Running 4.5GHz at 1.375v.

Any idea whats going on?

Probably just a bad overclock. Have you tried stress testing with anything else? I usually let Blender run for a few hours

I've tried realbench but only for like 15 mins and everything was fine, also tried Cinebench r15 a couple of times and those were fine too

maybe a bad overclock, i personally use RealBench and i run it for 8 hours. Some versions of prime95 are so intensive that even some stable or stock setups crash.

Going to need to run them longer than that. Run them for 30-60 minutes for each step up in frequency/voltage. Once you're happy with your overclock run a stress test again for several hours to ensure it's stable.

Just ran realbench overnight for 8 hours and didn't crash, 4.5Ghz at 1.375v

Gonna try a few more combinations

Prime95 is super sensitive to instability. Any instability or failure will result in a termination of the test At the end of the day if your CPU passes every other test but you come back to Prime95 and it fails, try dropping your clock speed by 100Mhz. if it passed then, you're stable and the rest of the applications failed to pickup on the instability.
