What's ECC?

[AdmiralEpoch]

I've been digging around in RDRAM and was wondering what the difference between ECC and non ECC was. Any help would be appreciated.

ECC is Error Correction Code or Error Correting Code.

Basically it is a way to make sure that the data remains free from one bit errors. One bit errors are the most common. ECC cannot fix more that a one bit error but anything more than a one bit are extremely rare.

Your CPU uses ECC in its cache.

This is a basic explination. If you need more info or something more specific just let us here in the THGC know.

Yeah. Also ECC RAM is a type of memory that includes special circuitry for testing the accuracy of data as it passes in and out of memory. If you are not setting up a server or not running data critical programs, then it's really not necessary to spend the extra $ for ECC memory. You won't notice any difference between the ECC and non-ECC ones.
