Frequent crashing/freezing, especially at idle. Once the processor is under heavier load it’s fine, it’ll keep going smooth for hours. but at lower energy states the CPU is super unstable. It often takes me about a half hour just to get the thing up and running steady, very frustrating. Sometimes it likes to crash right as it’s changing load levels/c-State, so just as it finishes loading files for a game just as the first 3d frame is rendered. Or vice versa, it’ll crash about 15 seconds after the computer returns to mostly idle when you exit an application.

I’ve tried a bunch of things, disabling c-states, manually setting dram timings, manually increasing power to various parts, enabling/disabling just about every relevant feature I can find. And of course looking for help online. I’m actually pretty sure the problem is in the motherboard, as one of the “fixes” I tried was going from a Ryzen 3600 to a 3800X, and the problem was the same.

I’ve looked around and it’s an issue I have seen other people having, though it’s not very common. But there’s no consensus in the root of the problem. It does seem to be that it’s some interaction between the motherboard and cpu. It could plausibly be the power supply, but I think that’s pretty unlikely. The ram is fine.
