When I upgraded my CPU to a Ryzen 9 5900X I did the research on DDR5 vs DDR4. I was considering a better version of the CPU that used DDR5 (I can't for the life of me remember and I'm not searching just for this comment)

I decided to keep my ram but get a new MOBO and CPU. The performance gain from DDR5 was minimal for my use cases. The ECC would have been nice but that's ok. I run memtest once a year and have only had ram die on me once.
