Datapoint: Rog X870E killed 9800X3D, I think I saw similar damage before
In the beginning, the desktop won't launch and mobo shows Q Code 00.
I replaced the current ram with new rams, then tested my SSD and GPU on the old platform they are all working.
Finally I took my CPU out, and saw the dark area in the middle, same as the mobo cpu slot. The damage on CPU and CPU Slot looks familiar, I think I saw them on Reddit before, but that's for older b650 mobos data points.
I think I'd have to use my old platform for now, and hope it won't take long for RMA.
I bought the Mobo in December 2025, and CPU at the same time, so the only good news is they are still under warranty.
The whole build is: Mobo: Rog X870E APEX (DEAD)
CPU: 9800X3D (DEAD)
GPU: Red Devil 6800XT
RAM: Trident Z5 Neo 64 GB (2X32GB) 6000MHZ CL30
Also tested Ram Corsair Vengeance 32GB Ram 6400mhz cl36 RGB
SSD: T Force Creator PCIE 4.0 1TB; Kingston PCIE 4.0 1TB; 970EVO 2TB; 860EVO 1TB
Cooler: Thermalright PS120SE
PSU: Super Flower Leadex III Gold 850 Watt
I didn't change the VSOC voltage, so I think it's running on the default voltage for December 2025 bios, the only thing I changed in BIOS is change the ram from 4800Mhz to 6000 Mhz CL30.
