Well that's DDR4. Apparently DDR5 was made with tighter tolerances and less safety margin, which is why many people argue ECC should be mandatory in DDR5 - it actually relies on it.
- userbinator 3mo agoThere are plenty of DDR5 machines without ECC[1], and yet they're not constantly crashing in the way that frequent bitflips would suggest. [1] DDR5's built-in ECC is not the same as traditional "end to end" ECC, and is meant to correct bitflips on the die, not between the RAM and the CPU, so ECC errors that you see are actually suggestive of a bad connection between the RAM and CPU.
- inigyou 3mo agoMost bitflips don't cause immediate crashes, or crashes at all. They just silently corrupt your data.
