I bought a 7700X from eBay a couple of weeks back that is refusing to play ball. When I put it in my B650 TUF Gaming Plus WiFi, it refuses to POST & the red CPU LED on the board is on permanently. The board is fine as it posts with a 7600 without any issue.
I picked up a MSI MAG X670E from the MM & with that, the behaviour is slightly different. The DRAM & CPU lights come on briefly but then disappear but I have no output on my monitor. I've tried the displayport from both the chip & the GPU, same result. Any ideas? I've had the CMOS battery out of both boards for ages so it's not a problem of old BIOS settings as far as I can make out.
