What is the difference between ecc and non-ecc ram pc3200?
ECC is error checking, there is an extra chip on the ram that
does this and it's only really useful for server machines. Also ECC
runs slower. Non-ECC has better performance and is used in most
desktop PCs. There is a lot more to it, but this should give you
the answer you need. For more info just type ECC vs. Non-ECC into
any search.
