When you enable the PPM option the CPU Voltage settings in the BIOS goes haywire.
What used to give you 1.35V will be giving you something like 1.42V.
Set your CPU Voltage to +50mV for example, save & exit, get into the BIOS again, go to the Hardware Monitoring section and check the CPU Voltage.
You're probably feeding your CPU with 1.45V+
