64x72 means RAM with parity check every byte has 8+1 bits. last is for parity check.
have a nice day,

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 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.
 
2 cents. ...

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