While using Prime95 for about the last 15 minutes, I observed that three out of four workers (cores) are completing the tests without issues, but one (Core 1) remains stuck on the initial test. There are no errors reported, just a delay. If I stop the run and restart it, the same pattern will occur, though a different core will be affected. Any advice?

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

It's tough to predict what's going on without a clear system description, voltage and temperature data, along with the P95 version. I need to note that P95 is disappearing from my memory... stop using after Sandy Bridge.

That's a 1.37 Vcore setting in BIOS or the highest recorded during testing? It's quite high; with AVX enabled, you can anticipate a notable voltage increase of 0.13 or more, which could push it above 1.5V.
What temperatures are we talking about? CPU package or individual core readings?
You can use HWiNFO (sensors only) to capture the maximum individual core temperatures and voltages.
1.37V in BIOS. According to CPUID and HWMonitor, the voltage never exceeded 1.356. Depending on the current test at P95, the temperatures range from 70-77°C for all cores and the package.
