Yes I have a list to go buy for my ram, 256/512 DDR CL=3 UNBUFFERED NON-ECC DDR 2.6V 64X64
What is the diffrance between, non-ecc, and registered, ram.

ECC RAM:
has error-correction built into it. ECCC RAM tends to be slightly more expensive than an equivalent non-ECC chip. ECC modules can be identified by counting the number of memory chips. If it's an odd number then one of the chips is for error-correction. An even number means it's non-ECC. ECC and non-ECC are also referred to as parity or non-parity respectively. Pretty much all denominations of RAM are available in both ECC and non-ECC versions, and motherboards don't really care which you use, though you should only use one kind in any given computer.
The vast majority of RAM currently in use is non-ECC. Pretty much only highly sensitive, mission-critical applications require ECC-type RAM, as personal and most commercial computing gets along just fine without it, and the error-correction tends to cause a performance hit.

Buffered RAM:
A term used to describe a memory module that contains buffers. The buffers re-drive the data through the memory chips and allow the module to be built with a greater number of memory chips. Buffered and unbuffered RAM cannot be mixed. The design of the computer's memory controller dictates which type of RAM must be used.
