VCC_SMB must be connected to 3.3V power supply (even if the SMBus features are not used) in order for the processor to function
properly.

from the motherboard VRM. If your system needs to
maintain VRM regulation with a disabled processor (OCVR_EN inactive), the VRM output minimum load specification should be 46
mA or less.
