Just upgraded to a Ryzen 7 5700x from a Ryzen 5 3600 on my B450-E ROG STRIX. The kingston a2000 nvme started developing issues. Sometimes it show in windows sometimes it won't. Thinking it to be a nvme issue i rmaed it and got a NV2 as replacement still same issue. I am on the latest bios ver 5102 before even upgrading.
