why doesnt everyone use ECC memory?

[Bondy3]

just curious,  as ECC only effects performance by 5%, I would think that everyone would want to use it,  but it isn't supported on a lot of CPUs,  just wondering why

Short answer. It cost more to produce and to make hardware that can run it.

Artificial limitation, to differentiate server processors from desktop processors and push users to buy more expensive motherboards (for example workstation motherboards with ECC and 10gbps network cards, or boards with more expensive chipsets) if they want to have ECC enabled.

It does cost more to make, although how much more is arguable. In the CPU the difference is probably insignificant, but the ram modules would need a bit extra capacity in order to store the extra info to allow errors to be both detected and corrected. I'm not familiar with the internal structure to say how this might be organised and thus how much extra storage would be required.
