When I was tuning memory I noticed that SoC Voltage has increased by a huge margin.
I thought about it and went ahead and tested 2 configurations to confirm my hypothesis that manual voltage setting causes SoC Power draw to go up.
1. Stock config, memory set to XMP.
SOC - Auto
VDDP - Auto
VDDG IOD/CCD - Auto
Notice the SoC Power under running Cinebench R20 is arround 5W.
2. Stock config, memory set to XMP. Same voltages set manually in BIOS.
SOC - 1V
VDDP - 0.9V
VDDG IOD/CCD - 0.9V
Now the SoC power has gone up to around 8W, which stays there even when idle and what actually bothers me that those 3W are actually taken away from CPU Power.
I am running B550 Tomahawk on latest bios.
