In fact, every time I look up the error rates for RAM, I wonder why consumer class RAM isn't ECC.I have read the latest Intel chipsets (Core i7 - Bloomfield) do not allow ECC RAM.
Prior to i7/i5, the Intel chips didn't care what memory was used, because the Northbridge handled it. i7/i5 went the same route AMD did a few years back, i.e., memory controller on the CPU. This means that you are required to buy the CPU that matches your memory, and not the other way around.*
That is, if you are running high availability equipment, and need ECC, or registered+ECC, you must get a Xeon.
Mark Allums* Intel did not quite match AMD; their i7 memory controller is more finicky, and is more risky for enthusiasts to overclock, as overvolting the memory is said to be "not good".
