Constant Hard Crash, unable to start a game
Whenever I start Battlefield 6, after loading shaders or a few minutes right after it, my computer completly freezes, I have to turn of the PSU, even power button doesn't respond There is no Log o...

GPU, PSU or RAM memory are definitely the problem, as I've changed them (Tested with RTX 4060, OCZ 750W PSU and Kingston RAM
I've tested all those options
Disable PBO
Set CPU PPT ≈ 120 W
Set SoC voltage ≈ 1.05 V
Force PCIe Gen 3
Disable Global C-States
None of them did any effect
But, i've messed with one thing that worked, Ryzen 9 5900X have 2 CCDs, disabling one (Using only one) in BIOS did worked
So this problem has got to have something with threads spread along those cores
GPU, PSU, and RAM can be ruled out (all tested/replaced), and other settings—PBO, PPT, SoC voltage, PCIe Gen3, C-states—had no effect. The key finding: disabling one CCD on the Ryzen 9 5900X completely fixes the issue.
This indicates that the B550M DS3H motherboard is likely the limiting factor. Its simpler power delivery, limited SoC VRM design, and less optimized Infinity Fabric routing struggle under BF6’s heavy multithreaded shader compilation across two CCDs. The fact that the system is stable with only one CCD active suggests a platform limitation rather than faulty CPU, GPU, RAM, or PSU.
Recommended solution: run BF6 on a single CCD (BIOS or CPU sets/ Process Lasso) or consider a motherboard upgrade for full dual-CCD support.
