Prime95 Question - Only 3 of 4 "workers" are progressing

[snurp85]

While running Prime95 (for the last 15 minutes or so), Ive noticed that 3 of the 4 workers (cores) are progressing through the tests just fine, however one of the (Core 1) is still stick on the very first test. There arent any errors or anything, but its just stuck on that test. If I quit the run and restart it, the same thing will happen, although the "stalled worker" will happen to a different core.

Any thoughts?

Hard to guess what's happening without a system description, voltages and temps as well as P95 version. I should mention thatn P95 is fading from memory ... stop using after Sandy Bridge.

Prime95 version 28.9 build 2

BCLK: 100 Mhz
CPU Multiplier: 44
Memory Multiplier: 32 (XMP Profile)
CPU Vcore: 1.37V
DRAM voltage: 1.38V

Temps are hovering around 70C during prime95

Also, why is P95 no longer used? It use to be the program you used for burn in and over clock stability checking

That's a 1.37 Vcore setting in BIOS or max recorded during test ? It's rather high; when AVX is present, you can expect a significant voltage boost of 0.13 or more.... that means you could be exceeding 1.5V

What temps ? CPU Package or individual core temps ?

You can run HWiNFO (sensors only) to record max individual core temps and voltages

1.37V set in Bios. According to CPUID HWMonitor, the voltage never went above 1.356. Depending on the specific test at the moment in P95, the temps are between 70-77C for all cores and the package.
