I have the same WHEA Logger error with my system:
- CPU: AMD Ryzen 9 5900x @ be quiet! Dark Rock 4 Pro
- RAM: G.Skill Trident Z Neo 32GB DDR4 3600 CL16 (F4-3600C16D-32GTZN)
- Mainboard: MSI B550 Gaming Carbon Wifi
- PSU: be quiet! Straight Power 11 750Watt Gold
- Case: be quiet! Dark Base 700
- GPU: MSI GeForce RTX 3070 Gaming X Trio 8GB
- SSD: Samsung SSD 980 PRO 500GB, 2 x 1 TB Samsung SSD 860 EVO
In my case the BSOD only happens when system is idle. In most cases after I have closed a game and been on the desktop for a short time.
I tested everything. Reinstalled Windows, checked temperatures, did different Benchmarks (Prime95, Cinebench, 3DMark, Memtest), different driver versions, Bios default settings, PBO off, different RAM configurations (2133Mhz, 3200Mhz, 3600Mhz). I couldn't identify the faulty part. I tested latest stable and BETA Bios.
I think it is the CPU which cannot handle the load change to idle and the vcore change when going from load to idle.
I contaced my dealer and new CPU and Mainboard is on the way. I really hope this fixes the problem

The current situation regarding BIOS versions and the state of the AGESA versions is really bad.
