Description

Leaving this here so that future contributors can look at this and fix it.

image

This is what I see when I boot up LHM for the first time; it is better than nothing, but wait, where are +5V, +12V, and the voltage sent to the DIMM sticks at least?

Let's consult another competitor software (HWiNFO64):

Well, first we see that HWiNFO64 is reporting 16 voltages, but LHM only shows 6 of them (it actually reports 15 voltages, though most are hidden by default); then we also notice the absence of the intrusion sensor. I am not sure if CPU (PECI) is reporting anything, too.


Of course, I tried to match some voltages on my own, so here's my findings (better than nothing I guess?)

  • Voltage #2 is +5V, Ri is 20, Rf is 10;
  • Voltage #5 is +12V, Ri is 56, Rf is 10;
  • Voltage #6 is VDDCR_SOC;
  • Voltage #7 is DRAM (or VDIMM);
  • Voltage #11 is VIN5 (in my testing this was fixed to 1.024 V so idk what that is);
  • Voltage #12 is VPPM, Ri is 3, Rf is 1 (in my testing this was fixed to 2.528 V using 1.35 V profiled DIMMs so idk if the scale is correct);
  • Voltage #13 is unknown to me;
  • Voltage #14 is VDDP;
  • Voltage #15 is CPU VDD 1.8V, Ri is 1, Rf is 1;

I don't know if Voltage #13 is PREM_VDDCR_SOC because in my testing HWiNFO64 reported a constant reading of 0.949 V, while LHM reported 0.944 V.

Research direction

Reproduce the missing readings on the ASRock X570 Taichi in Libre Hardware Monitor and compare them with the HWiNFO64 results shown in the issue. Use the listed voltage mappings and the absent intrusion sensor as the checklist; done means the expected sensors are reported with correct names and values.
