Well I'll edit this then, from a pretty sketchy test it seems VID indeed does nothing in manual OC mode. When doing Small FFT AVX on this 3.8GHz setting, temps instantly jump to 94-95C, so I quit the test immediately. That was on VID 1.275. Setting VID to 1.20 and 1.10 (where it drops to 1.00) does not scale at all with either power usage or temperature (confirming that the power usage number is correct).
Edit2// Confirmed that least lower VID and/or Ryzen Master voltage setting in general does nothing when on Manual OC in the bios. Setting VID to 1.1v still allows me to get CCX1 to 4.5GHz.
Why setting VID is even a thing (either in BIOS or Ryzen Master) is beyond me.
