Ask HN: ECC Memory vs. DDR5 for Stability?

I'm looking into building a new computer soon. With DDR5 having single bit error correction, is ECC memory worth it for desktop computers? I tend to keep my machines for a long time and tend to notice some instability as the memory gets older (seems to be memory in at least 1 case as changing the memory helped). I was planning to do ECC this time, but DDR5 sounds like it could be good enough for me. I'm wondering if anyone has any input on that.
