My point is that once RAM is initialized in ECC mode, then the OS will see it. The motherboard can't support ECC mode but then screw up EDAC. That's why I said "as long as the memory is correctly initialized in ECC mode". It's a binary thing. Either the motherboard supports ECC, or it doesn't. If it supports ECC then you can always tweak the scrubbing from the OS.
