From my limited knowledge of electronics-in-space, isn't ECC memory a hard requirement to correct for bit flips due to solar radiation/particles? But DDR5 having ECC be standard across the board may make this a non-issue.
- Cthulhu_ 5y agoKinda, yes, but at the same time, servers here on earth have moved away from (expensive) ECC in favor of resilient software, disconnected services (job queue based) and redundancy. Cheaper to have a dozen computers that sometimes break than three with lower risk (but they still break).
- zitterbewegung 5y agoFor consumers no but for things like large simulations or even deep learning you want to have ECC memory. Intel only enables it on Xeons but AMD doesn't officially support it on their consumer chips but sometimes it works.
- my123 5y agoIt's locked down on AMD customer APUs, only not forcefully disabled on AMD customer CPUs that do not have integrated graphics. (Ryzen PRO parts have it officially supported)
