RAM Differences
This is a discussion about RAM Differences in the Windows Hardware category; What is the difference between 64x64 and 64x72 RAM? What's the point in those things? Anyone have a clue Thanks

64x72 means RAM with parity check every byte has 8+1 bits. last is for parity check.

I think it's called ECC error control and correction. It should give more stability to a system but it's ment for servers, cos it's a bit expensive.
ECC=Error Correction Code

ECC memory is also slightly slower, because every read/write operation involves error checking as well as just the read/write.

ECC and parity block checks are 2 different things.
Parity blocks are either 0 or 1 ... on or off. Granted this is a a good quality of control agent. But what if the data and parity blocks are corrupt.
ECC adds additional information about the parity as well as the data blocks.

Some of the older boards didn't have parity checks on board so the ram had to have it on the chip
