Asrock B650m Pro RS (BIOS 3.15 AGESA PI 1.2.0.2b)
RAM: 2x 16GB Kingston Fury Beast 6000mt/s - Running at the EXPO profile
PSU: Seasonic FX 850w
CPU: Ryzen 7 7700 (made in china variant)
Windows 11, all drivers up to date.
Build age : 2 months
All cables seated well, the ram also.
Problem:
The PC will freeze randomly, usually on low load. Occurrence - once per week after about 6-7 or more hours of use.
OCCT stress test - PASS
Windows Memory Test - PASS
TestMem5 - PASS
Behaviour when it happens:
1. The mouse will slowdown and eventually stop moving. Nothing on the keyboard will respond. Solution - force shutdown.
2. The mouse will slowdown, but I can still move it. The audio will play for 1 sec after 1-2 min. Can't use soft restart or shutdown. Solution - force shutdown.
Windows Event logs doesn't tell me concrete reason. Only one potential error with the Solidigm NVME driver and the wireless Gamesir game controller that occasionally cause the system to throw error on shutdown.

Experiment:
Bad silicon lottery? GFX Curve Optimizer - I set it to -20, the system boots. The mouse will slowdown, the screen will go black and driver will timeout. Similar mouse behaviour but it self recovers unlike the stock voltages. Tested for 10-15 min.
CPU Curve Optimizer - at -20 Tested for 1 hour OCCT and it's stable.
I have no way to replicate the problem consistently. The synthetic stress tests may not trigger the issue at all. Does anyone have any ideas how to pinpoint the problem to one area?
