AMD Ryzen 3900x: 0xc0000229

Two weeks ago, my new build stopped booting, reporting 0xc0000229 and LED indicators (POST stage) would show various codes, most often 55. Turns out, my cpu – and specifically the memory controller – went bad. Thought I’d leave this out here on the internet, since it took me a while to debug 🙂
