Memory type? (ECC vs non-ECC) - memory testing

	Actually, parity memory will usually detect the errors (usually, as in
as usually as ECC will correct them).  You can set up the BIOS (assuming
it supports Parity memory) to halt on a memory error (or there may be
other, more viable options).  I'd stay away from non-parity if possible.
