ECC != parity. I know. Sorry for not
being clear in my previous mail. I meant: Usually
the terms "parity SIMM" or "ECC SIMM" are used for SIMMs with 36 data
bits. If the extra 4 bits are used for parity or ECC depends on the
memory logic in the machine, not on the SIMM.
There are also some machines (some sun4c and some EV5 Alphas) that need
33 bit RAM. They use one parity bit per 32 bit word.

No need for ECC RAM
ECC == parity? I always
thought the SGI machines need ECC / parity
RAM. (I.e. SIMMS with 36 data bits.)
