There are SIMMS that implement ECC the hard way - with ECC hardware on SIMM (amazing but true). You of course don't want those, what you want is true parity (one extra memory bit per byte of data). The chip count method should work in virtually all cases. I have always gotten the "right" stuff from www.thechipmerchant.com (*usually* though not always on the first shipment). Natoma and Orion (82450 and 82440) boards should all implement ECC (at least those chipsets support ECC and the SuperMicro boards that use these chips make the support available).
