B550 Steel Legend BSOD when auto voltage

Good Morning:

I have been having a reoccuring issue with my PC BSODing with DPC Watchdog Violations unless I manually set the voltage on my processor. If I set it manually I have no issues. The BSOD Points to amdppm.sys as the module. When I set it manually and have it under load (gaming etc) temps are below 60C and idle temps are around 30-35C. Manually setting the voltage my system is stable, sleeps/resumes etc with no issues but with manual voltage I miss out on the processor being able to throttle up or down depending on what I am doing.

I originally thought it was my cooling but I have tried multiple coolers and the most recent one was installed by a pro with no change.

I also suspected RAM but I replaced my RAM yesterday with approved Corsair Ballistix 3200 and thought maybe I could set the system to auto now but no luck.

This was probably caused by the following module: amdppm.sys (amdppm+0xb992)
Bugcheck code: 0x133 (0x0, 0x501, 0x500, 0xFFFFF80410F05330)

description: Processor Device Driver
Bug check description: The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL or above. This could be caused by either a non-responding driver or non-responding hardware. This bug check can also occur because of overheated CPUs (thermal issue).
The crash took place in a Microsoft module. The description of the module may give a hint about a non responding device in the system.

I already had global C-State disabled.

I tried setting processor voltage to auto and then enabling offset mode but I could not find the option for setting the offset voltage in the bios. Just setting it to auto voltage and then offset mode resulted in the same BSOD.

Thank you for the advise, the second option helped me solve the same issue on a similar system.

For anyone else having this issue just do 2. Boot into BIOS\OC Tweaker\External Voltage Settings and Load-Line Calibration to set the option "CPU CORE/Cache Voltage" to "Offset Mode" and set the "Offset Voltage" to "+50mV" or "+100mV".

Bare in mind you don´t need to include the mV part, I set the value to +100 and that did it apparently.
