The Triton HX chipset supports ECC, if you have 9-bit SIMMs. 9-bit EDO SIMMs exist, but are rare. 9-bit non-edo (FPM) ("true parity") SIMMs are common. Somebody (finally! ) realized that a 72-bit wide word (64+8) has enough bits to easily implement ECC. ECC is *much* better than parity. There is a performance hit, though; Read burst timing for non-ECC can be x-2-2-2, but with ECC it must be x-3-3-3. Intel has a document ("ECC Overview") on their WEB site. Evidently, the PPro itself supports ECC. Dunno about Linux support. Probably not yet. If I had 9-bit SIMMs, I would start working on it myself.

I just recently saw an advertisement for a Dell computer with a P6 motherboard & CPU that includes "64MB EDO RAM with ECC".
Are there in fact x86 motherboards that support ECC RAM? Can such a motherboard provide better error recognition & recovery then a simple "parity error"?
Most importantly, can (does) Linux take advantage of this?
