ECC RAM (Unbuffered) has error correction but no registers and is suitable for workstations and PCs that will be left on a lot.
Standard RAM (Non ECC) has neither error correction or registers and is suitable home PCs and gaming rigs.
In all cases the memory controller has to support the type of RAM you wish to use, as far as I know the integrated memory controller in AMDs Non Opteron 64bit CPUs, support ECC and standard RAM (NOT Registered) and there shouldn't be any real speed difference between the 2 as, although each read is an extra 2 bits wide, you're still doing the same number of reads per second, and unlike with Registered / buffered RAM, the memory is read directly so there shouldn't be any difference in latency either, though there will be a price difference.
I tend to leave my PC on all the time as it's always doing something, so my goals are reliability and low power consumption then speed.
