NON ECC memory

This may seem like a stupid question, but I've just got a new motherboard and the manual says it supports ECC memory. So does this mean I won't be able to use my NON-ECC memory with it.

I won't be able to check it myself until I get my new psu.

thanks for any help

Can I replace non-ECC memory with ECC memory?

Answer:
ECC (Error Correcting Code) memory is parity memory and non-ECC memory is non-parity. Parity memory has an extra chip on the module that checks for errors in the transfer of information to and from the memory. So if a memory module has an odd number of chips, it is parity RAM.

Many motherboards support both ECC and non-ECC memory. Some sources say you can even mix the two types of RAM and the ECC RAM will work as non-ECC memory. However, most memory companies do not support mixing the two types, so try it at your own risk. Since most motherboards will accept ECC memory, it often depends on if your computer's BIOS supports it. You may have to check your computer's manual to find the answer.

If you have a choice, non-ECC memory is typically cheaper than ECC memory and works slightly faster. So when in doubt, use non-ECC memory.

As an amplification for those interested, an explanation of parity and ECC memory, and the differences can be found here click here

Parity is a simple check for an error in a single memory location - it says it's good or bad, no more.

ECC, as it's name implies, can do significantly more - it can actually correct certain errors in data read from memory.
