comment What is server memory?
What Mr. AndreÇ°a describes in the second paragraph is not how ECC memory works. It uses a Hamming code (as explained in the Wikipedia article he cites). Moreover, it is not true that "[t]he downside of this is that two errors could occur and the number of bits would be right, so they would be undetected." ECC memory will correct an error where one bit is flipped, and it will detect an error in which two bits are flipped, protecting data integrity. To keep this in perspective, though, a flipped bit happens from time to time, whereas two flipped bits is a rare event.
