RAM Differences

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.

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.

Some motherboards don't support it though

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
