I get an orange QLED with a CPU, which on ASUS MBs signals a RAM issue, but I'm sure it's related to the CPU/socket, as this and another CPU of the same model were working here even a few days ago. In the meantime, the socket suffered a lot of worrisome pressure and scraping during CPU movement. While I don't believe it could be an exclusive problem of the one CPU, I did also clumsily send it flying across the room in all this.
This motherboard is itself a recent RMA replacement, hard to believe they'll accept it. (The previous one displayed a mix of orange and red QLED for a CPU socket short circuit btw.)
