About two months ago My 9950X3D died. I presume it the memory controller died because my asus board reported a ram problem. It was with a 2x48GB 6000 ram. Which was not supported by the board (at least on the docs). I also limited the max PBO by 400Mhz and limited VDDIO to 1.3V. But it still died while shutting down cachyOS.
