On: Nvidia announces next-gen RTX 5090 and RTX 5080 GPUs

The 4090 indeed does have ecc support

[sliken → gregoryl]

Yes, but ECC is inline, so it costs bandwidth and memory capacity.

[fulafel → sliken]

Doesn't it always. (Except sometimes on some hw you can't turn it off)

[sliken → fulafel]

I 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 → sliken]

Anything 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...

[sliken → FuriouslyAdrift]

Sure, but it's very limited. It doesn't detect or fix errors in the dimm (outside the chips), motherboard traces, CPU socket, or CPU.
