I'm not sold on on-die DDR5 ECC providing protecting. On-die ECC allowed DDR5 to be competitive with DDR4. Is it really protecting your data at rest if the DDR5 die is running at such tolerances that it's correcting single bit errors from internal signalling issues every transaction? It's only single bit ECC, if something else outside of the die(Cosmic Ray, sudden voltage change, sudden temperature change) induces a bit to flip while the internal circuitry causes a different bit to flip your data is now corrupt. https://www.atpinc.com/tw/blog/ddr5-what-is-on-die-ecc-how-i... |
