Default DDR Vs DDR SDRAM

Im looking for memory for a m8

He's looking for 2X 512 DDR SDRAM

Is DDR memory the same as DDR SDRAM?

His MB manual states DDR but Cpuz says DDR SDRAM is installed

Cheers for looking

They are two names for the same thing.

SDRAM stands for Synchronous Dynamic Random Access Memory.
Both the single data rate and the double data rate versions
are synchronous designs. The term SDRAM by itself is used
as a shorthand for the single data rate (original) type.
The modifier DDR is meant to remove the uncertainty, and
tell you that you are dealing with DDR SDRAM (the double
data rate version).

SDRAM single data rate - i.e. PC133
DDR or DDR SDRAM double data rate - i.e. DDR266

When shopping, other adjectives are unbuffered or registered,
ECC or non-ECC. The most common desktop memory is probably
unbuffered non-ECC, but some desktop motherboards do support having
unbuffered ECC (adds error detection if the chipset supports it).

Registered memory is typically used on servers.

Depending on whether you are buying from name brand retailers
(Crucial) or the skum of the earth on Ebay, will determine just
how careful you have to be when buying product. The user manual
for the motherboard should at least make clear the general
characteristics to look for.

If you can give more details, such as the motherboard make and
model, or at least what chipset is used (875P, 440BX, and so
on), then someone can give you additional advice. Shopping
at Crucial or Kingston takes all the guess work out.

Paul, thanks for your detailed explanation about DDR vs SDRAM. I suspect it
helped quite a few people (including me) lurking on the newsgroup.
