ECC RAM Compatibility

How do I know if my motherboard is compatible with ECC RAM? I am not talking about Registered Memory, as I know that has different motherboard requirements.

But will ECC DDR RAM work with any motherboard that accepts regular DDR RAM or does your motherboard need to explicity support ECC RAM?

Reason I am asking is that I might be able to get some ECC DDR RAM real cheap, I just don't know if it will work with my motherboard. I can't find anything in my manual or online regarding it *not* working.

Thanks!
 
More info would be nice...

And why do you need ECC RAM? because it's more expensive? because it's for servers and won't benefit someone playing games, video/photo editing, etc.?
 
I can get it cheap. I just wanted to know if it would work with my board. Not registered, just regular DDR, but ECC.
 
It "should" work fine if it is not registered memory. Many desktop boards even have an option in the BIOS to enable/disable the ECC function if your installed ram supports it.

It depends on the motherboard and/or platform.

On the AMD side, all Athlon 64 processors (Socket 754 or 939) have memory controllers which support ECC memory. Most Socket A motherboards (for Athlon XP processors) do not support ECC.

On the Intel DDR1 (as opposed to DDR2) side, however, only the higher-end 875P chipset supports ECC; the 845, 865 and 915 series don't.

It would be better if you tell us exactly which motherboard and chipset you have.
 
Hmm, I'll try to get that information. This is for my GF's Dell Dimension 4600. I'll crack it open tonight to see if I can get the chipset information

The Dimension 4600 uses the Intel 865 series chipset, which means that it will not support ECC memory - and the way Dell does its BIOSes, the system will not even POST at all when ECC memory is used.
