Fun fact: DDR6 contains built in ECC by default. RAM sizes are getting so large it's causing issues in the field and also issues with yields
So, the industry thinks its a problem.
- userbinator 11mo agoIn other words, the industry has gone to shit as usual, starting with rowhammer. But my question still stands.
- toast0 11mo agoDDR5 has built in ECC too. Unfortunately, AFAIK there's no error reporting mechanism, so while it should reduce error rates, it likely increases error severity. Assuming no bitflips between the ram module and the cpu, ECC on the ram corrects any single bitflips, but multiple flips are uncorrectable and must pass through, so any incorrect value the cpu gets has multiple bitflips.
