Hello,
I've been struggling with this problem for quite some time. I'm using AMD PBO, reboots and the subsequent error in the log were sporadic, system crashes happened many times completely unpredictably, sometimes even under absolutely minimal load. When I was always able to simulate the situation, it was in 3D Mark, specifically the "Time Spy Extreme" benchmark - if I used the default combination of 3D GPU+CPU tests, it went to the error described here for the CPU test:

!!! DISCLAIMER !!!
I disclaim any responsibility for the description below. Each build is unique and not every setup may work correctly. That said, I have successfully set up the below on my build, if you experience HW/SW damage to your system I am not responsible for this, following the setup is your responsibility !
What me helped:
- Memory voltage within XMP increased from 1.35V -> 1.37
- Curve optimizer (negative) all cores Magnitude -> 0
What I have changed in the BIOS in general compared to the default and what the possible error may be related to in different combination (this one is functional)
OC Tweaker:
XMP Profile: XMP 2.0 Profile 1: DDR4-3200 16-18-18-38 1.35V
DRAM Voltage: 1.370V
Infinity Fabric Frequency and Dividers: 1600MHz
Advanced:
AMD Overclocing / Precision Boost Overdrive
Precision Boost Overdrive: Advanced
PBO Limits: Manual
PPT Limit [W]: 120
TDC Limit [A]: 75
EDC Limit [A]: 130
Precision Boost Overdrive Scalar: Auto
Curve Optimizer
Curve Optimizer: All Cores
All Core Curve Optimizer Sign: Negative
All Core Optimizer Magnitude: 0
I hope that the description and the BIOS documentation will help you.
Have a nice day,
Pavel.
