PC crashes frequently in high-demand titles yet operates flawlessly in League of Legends.
Hello, I see you're dealing with some puzzling PC problems. Let's review your setup: motherboard MSI MEG X570, Ryzen 9 5950X, 16GB RAM, RTX 3090, NVMe SSD, and EVGA PSU. At first, the boot process failed due to a CPU error on the motherboard. After replacing the RAM, the system functioned normally for basic tasks and games like League of Legends. However, performance drops when running intensive applications such as Cyberpunk, Helldiver 2, Elden Ring, or stress tests like 3D Mark Time Spy.
You've tried reinstalling Windows, updating BIOS, reverting to original RAM (which caused the error again), and updating drivers. Also, testing the GPU, NVMe drive, and power supply in another machine resolved the issue there. Since your system uses an AM4 form factor, you're cautious about upgrading components without knowing the root cause.
Could someone share advice or possible fixes for this situation?
Consider it a temperature concern. Install hwinfo64 and examine CPU temperatures via the "sensors only" section.
I suspect a C-state or P-state problem. It seems League isn't reaching the highest P-state, so it might be stuck in a lower state consistently. Possible tests include adjusting Windows Power Plan settings for the CPU, turning off C-states in UEFI, and limiting TDP to 105W with PBO's ECO mode. For GPUs, PCIe C-state controls let you switch between versions, negotiating as low as PCIe 1.1 to conserve power. These UEFI options can be disabled and checked using GPU-Z by comparing idle performance versus game usage.
