First of all, only RAM with parity bits (or ECC) can generate such NMI
(the motherboard must support this as well, of course).
Most motherboads can be configured in ECC mode, and they correct 1-bit
errors. 2-bit errors are reported and not corrected, but the probability
of such error is nearly zero in normal conditions (unless your hardware
is defective, of course).
CPU caches do ECC as well, and possibly can generate NMI requests. However,
they use static RAM (as opposed to dynamic) and bit errors should not
happen there.
