ASRock B450M Pro4 Reporting CPU(PECI)?


New Member

First of all thank you for all your hard work, this is really a great and polished tool :).

I have recently built a new PC and was looking to monitor temperatures across my rig for stability:

ASRock B450M Pro4
Ryzen 5 2600

I noticed in the temperature sensors for the motherboard that CPU (PECI) is listed.  I thought that PECI was only for Intel CPUs?  Is this correct, or am I wrong?

I have attached the report & debug file for you.

Thanks again!

That's right, PECI is a private Intel interface. This is a generic readout from the SIO chip and I'm not sure what it represents in this case.
It might be reporting an invalid value, or mirroring one of the others. It's probably better to ignore it on AMD systems.
