ECC DDR3 Compatibility

post #1 of 7
Thread Starter 
Hello,

I've been trying to find out whether or not I will be able to use ECC DDR3 on my motherboard to properly support ZFS.

The board in question is the ASUS P6X58D-E


https://www.asus.com/Motherboards/P6X58DE/

At the moment I have a i7 950 installed, but I am about to purchase a Xeon X5660 (or X5650, X5675) to replace it.

The motherboard specs say it only supports Non-ECC RAM, but from what I have read on my searches, depending on the board, the CPU is responsible for handling or not handling ECC RAM, meaning after I install the Xeon, ECC memory may work OK.

It seems as long as I stay away from registered/buffered memory (which needs special circuitry on the motherboard to support it properly?) chances are good, especially since the board is a "-E" model, ie primo model

Can anyone please confirm either way?

I personally don't know. I did some google-fu and only came up with a post that generally says all 3 parts (cpu, board, ram) need to support ecc for ecc to be enabled. if you have an i7, no ecc. if your ram is not ecc, obviously no ecc. if you board specifically says no ecc, no ecc, even if you have xeon and ecc ram. you can put ecc ram in that board with the xeon and it will work as RAM, but it wont have ecc enabled.

If you're looking for 1st person experience with the issue, then i'm not any help, sorry.

I'm going to go ahead and say EEC functionality won't work on that board even with the Xeon.

Just checked our own database and it looks as if it only supports Non-ECC memory modules.

Buy the ECC ram, and if it doesn't work, should be able to pick up a cheap x58 second hand board that can replace the current one smile.gif

Thanks for checking the DB, now I know.
