[HwInfo + TheStilt]AMD Ryzen "Power Reporting Deviation" -metric in HWiNFO

https://www.hwinfo.com/forum/threads...n-hwinfo.6456/

Quote:
In short: Some motherboard manufacturers intentionally declare an incorrect (too small) motherboard specific reference value in AGESA. Since AM4 Ryzen CPUs rely on telemetry sourced from the motherboard VRM to determine their power consumption, declaring an incorrect reference value will affect the power consumption seen by the CPU. For instance, if the motherboard manufacturer would declare 50% of the correct value, the CPU would think it consumes half the power than it actually does. In this case, the CPU would allow itself to consume twice the power of its set power limits, even when at stock. It allows the CPU to clock higher due to the effectively lifted power limits however, it also makes the CPU to run hotter and potentially negatively affects its life-span, same ways as overclocking does. The difference compared to overclocking or using AMD PBO, is that this is done completely clandestine and that in the past, there has been no way for most of the end-users to detect it, or react to it.
My X570 Master running CB 20
80% deviation while PBO is on with vcore undervolt.
90% with PBO on and no undervolt

Am i good or bad Stilt?

Not exactly new. My 4670k thinks it uses 25 watts running prime95 small fft at 4.2ghz. Thanks, MSI.

Just reset bios, enabled PBO only, ran CB20.

I was staying right at 92% for the whole run.
