Ryzen 5500. Pulled from working system. HOWEVER, it has a weak memory controller and is picky about memory. This CPU tortured me as I was trying to get dual rank ram in dual channel config to post reliably. It may not work with certain types of memory, it may not post in dual channel config. But it works, and if you just have one stick of ram it should work absolutely fine.
But it also may work perfectly fine with single rank memory in most computers. If it doesn't work, happy to exchange/refund. Pickup only.
