Ryzen 9 7950X Idle-Crash

I built a PC with Windows 11 in preparation for the coming Windows 10 obsolete in 2025. The plan is to use non-OC settings over OC platform for a reliable productive engineering work for the next 7 or 10 years. That works for me in current Windows 10 system.

With clean Win11 installation, I boot Win11 Pro, login, let it sit there idle. In 2 - 12 hrs, the system crashed and restart to login screen. Event Viewer shows Power-Event 41. My test setup is such generic and low-speed (see below). Something about power management is not right. Immediately I suspected motherboard. So, ASRock sent me another motherboard. However the idle-crash issue persists. Any good suggestion?

The system passed all heavy-lifting and burn-in tests on memory, processor, and storage etc.. The issue only happens when it's doing nothing after awhile. Another observation is CPU always runs over 4.2 GHz at near 0% utilization. Why would it need so much power at idle?

CPU - AMD 7950X
Motherboard - ASRock X760E Taichi Carrara
BIOS - 1.24 with AGESA ComboAM5; No OC setting; fan and storage configured; lowered to DDR5-3600 for test
RAM - (to cross out this factor) one stick running at 3600 of Corsair Vengeance 64 GB (2 x 32 GB) DDR5-6600 CL32
PSU - Thermaltake Toughpower GF3 1000W
GPU - Dell 86RMK Nvidia Geforce RTX 3060 TI 8GB GDDR6 PCIe
C: - RAID 0 of 2 M.2 WD Black 1TB SN850X NVMe
- HDD WD Red Pro 20 TB on 2nd AMD PROM21
E: - HDD WD Red Pro 20 TB on ASM1061 on 1st AMD PROM21
OS - Win11 Pro; all update till now
AMD chipset driver -
ASMedia 106x driver - Tried both ASRock stock & WHQL
AHCI HIPM - enabled
OS Sleep mode - off

AMD sent me another 7950x. Tested 10 days. It can stay alive without crash only when BIOS has Global C-State disabled. The RMA'd CPU has exactly same bug. Frustrated.
