The 4090 indeed does have ecc support
- sliken 2y agoYes, but ECC is inline, so it costs bandwidth and memory capacity.
- fulafel 2y agoDoesn't it always. (Except sometimes on some hw you can't turn it off)
- sliken 2y agoI believe the cards that are intended for compute instead of GPU default to ECC being on and report memory performance with the overheads included.
- FuriouslyAdrift 2y agoAnything with DDR5 or above has built in limited ECC... it's required by the spec. https://www.corsair.com/us/en/explorer/diy-builder/memory/is-ddr5-ecc-memory/ https://www.corsair.com/us/en/explorer/diy-builder/memory/is...
- sliken 2y agoSure, but it's very limited. It doesn't detect or fix errors in the dimm (outside the chips), motherboard traces, CPU socket, or CPU.
