"Registered modules have additional components (registers) placed between the incoming address and control information and the SDRAM components. These modules are typically used in Servers due to their added reliability (they place much less of an electrical load on the memory controller and therefore make it possible to have as many as 16 or 32 modules in a large system)."

From what I've read, a stick of memory that contains registers will actually hold data for one full clock cycle before it's passed on. A small performance hit is generally incurred as a result. Registered memory is all about scalability and stability. "

Basically, if you're just building a desktop (gaming, office, whatever) machine, then ECC registered memory is a waste of time. If you're building a computer that you absolutely can't have any downtime (ie. a server), then you might consider ECC registered memory.

Edit: And I would not mix and match them.

Hi seven,,,
thanks for the reply,,
Was only wondering about ecc , because i was looking at a pair of 256mb sticks of pc800
for my desktop comp.
Couldnt remember whether or not iwas the ecc or none ecc that was already installed.
I ended up taking the comp apart and checking the memory already installed.
Was ecc,, so i bought the memory ,,,,hopefully it will install correctly when i get it.
Anyhows,,, i now understand the difference,,
Cheers mate,, :whistling:
