When purchasing used Ryzen chips, verify the CPU pins.
Appreciate AMD designing CPUs that function at 99% with missing pins. A few months back, I purchased an ASUS TUF X-570 PRO equipped with a Ryzen 7 3800XT from a seller on Kijiji at a great price. The buyer uploaded the BIOS settings in front of me to confirm compatibility. Everything arrived with all accessories included, giving me a solid advantage. Spent many weeks trying to resolve the issue of missing onboard audio, suspecting a faulty motherboard. While searching for the board’s serial number, I realized the WMI output didn’t align with the box label. After disassembling the unit, I found no official board label—just a partially taken apart machine. Eventually, I discovered a severely bent pin and two completely severed pins on the AM4 socket. The chip’s pinout chart confirmed those two were linked to HD Audio controller clock/sync, explaining the audio absence. Fortunately, this was the only concern that could’ve caused problems for me (I already have multiple USB audio interfaces), but seriously... [TL;DR] If you’re buying a used motherboard/CPU combo with a Ryzen chip, double-check every pin before purchasing! Post performance isn’t perfect, and I learned this the hard way!

I received a solid discount between the MSRP retail prices of both items. It would cover an AE7 plus a decent new keyboard. I had intended to upgrade my 4th gen i5 to a B550/R5 3600 combo, but at just $140 more, the secondhand X570/R7 3800XT was too attractive to ignore.
It’s disappointing you got such a system, especially since the seller didn’t disclose any issues upfront. Honestly, I’d avoid removing my heatsink or taking my CPU out for a sale. Better to go to another buyer instead.
When offering the system as a complete package, everything is perfectly balanced. If I ever needed to buy a ready-made version later, I could ask for an operating system that starts automatically to confirm full functionality before buying. In my situation it was just a board and chips on a testbench without a heatsink; it would have been unnecessary to remove it and verify everything.
