Conflicting vCore measurements - what program to use?

I tend to gravitate towards HWiNFO64 however, today, while tuning my new 8700K from Micro Center's black friday sale, I noted it read the vcore as 2.2v, which cannot be right. I then fired up CPU-Z and it read 1.09v, which also doesn't seem right - this is on a 8700K @ 5.0Ghz, so I'd expect something long the lines of 1.15 to 1.25v at load. Under prime95 blend the above were the results I got.

Am I correct in my assumptions? What program do you all use to monitor vcore and other parameters during testing?

 

I should also add that it will occasionally hard crash my system - no bsod, nothing.

Is that overvoltage or undervoltage? Something else? I'm trying to get a stable system by tomorrow and this is really throwing a wrench into my plans. Tuning my 7600K seems like a walk in the park by comparison.

Bios.

Yeah really can't access that while testing now can I? Mainly because I'd like to know what level of LLC to use.

I though HWinfo was accurate but now I have doubts

You can try HWMonitor or Everest. I had a problem with a Gigabyte board and HWinfo on some sensors, but not with HWMonitor. Some programs and motherboards just don't really get along and it just reads nonsense. You can however stab the backside of your CPU socket with a multimeter, that will be the most accurate measurement you can get ?

CPU voltage being 2.2V is high but not unheard off i guess. core voltage is the one you are looking for in HWInfo64. HWInfo64 generally picks up the right sensors from what i know, just make sure you are looking at the right one

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

can you send a screenshot of what HWInfo is showing you? im sure the voltages are fine but i mixed them up myself a load of times lol

Are you running the latest version of HWiNFO?  They usually stay on top of the latest hardware, but you may need to use the beta if the current version isn't reading correctly.

yah your motherboard dosnt know what voltage your CPU is running at, you are looking at the wrong number im pretty sure. this is what the core voltages look like in HWInfo64

Huh, I've only seen individual vid per core on laptops. It wasn't there with my 7600K either, only vcore - though it was the correct vcore at that time.

I updated to the beta version and that sorted things out somehow, still no vid though
