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.
Whocrashed output:

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.

Dear Flatlineskillz,
Thank you for the posting.
Regarding your problem we have two suggestions below for you to verify.
1.Please go to BIOS\Advance\AMD CBS\CPU Common Options to set [Global C-state Control] to [Disable] to try.
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".
Thank you,
Best wishes,
ASRock TSD

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.

Dear Flatlineskillz,
Thank you for the test and reply.
Please restore the BIOS to default setting and don't overclock the CPU/Memory frequency to try.
If possible, please also use other CPU or memory to cross test.
Thank you,
Best wishes,
ASRock TSD

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.

Just curious, did you do only option 2; "Offset Voltage" to "+50mV" or "+100mV"?
In my case it also solved the problem of random BSODing...
I adjusted to 100mV in BIOS version P3.20, with a AMD Ryzen 7 3700X.
I also did option 1, and now wonder if I should change it back and have only option 2 enabled....
Thanks, Matthijs
