the thing about ECC memory is that it doesn't support reporting of ECC errors, so it ends up just hiding the fact that your RAM has started to go bad. this is good if you replace RAM every n years, but not if you intend to use the RAM until it starts degrading.

Wait that. It does, and that's the point. Although the CPU and motherboard do of course also have to support it, but with AMD it is possible. I do it on a 9800x3d.

One bit errors are always both detected and corrected. Multibit errors are mostly at least detected.
