That's right, I'm sorry if I worded it ambiguously in my previous posts. ECC RAM is considerably slower than non-ECC RAM, but nowadays it's mostly because of looser timings and lower frequencies. I'm well aware that there are people who claim that frequencies beyond the ECC standard are liable to cause data loss (for reasons usually left unspecified), but I've never seen any reliable data to support that claim, as long as the frequencies and timings tested by the manufacturer are maintained (not to be confused with people who overclock RAM way beyond its tested specification and experience instability). On a further note, while the implementation of ECC itself is very fast for modern RAM, the same is not true of VRAM on GPUs. At least as implemented in NVidia Tesla GPUs, enabling ECC has a huge performance penalty by itself.
