SD RAM is the old standard.
It was replaced by RD RAM and DD RAM.
The new standards are faster mainly because of the way in which they work.
DDR stores information as the chips charge, and release their electrical energy whereas the old SD RAM used to store information simply as it charged. Therefore the new DDR is roughly twice as fast at the same clock speed.

The main difference between DDR and RD RAM is simply that of liscencing.

Intel originaly only liscenced RD RAM technology to work on Motherboards that were P4 ready.

This was another marketing faux pas from Intel as RD RAM is slower yet more expensive the DDR. (Rather like the ATHLON / PENTIUM situation).

I think you can now get P4 systems that work with DDR but why bother.
As long as you have an Athlon you cannot use RD RAM.
If you dont have an Athlon then it doesnt matter a Jot which of the new standards you are using anyhow cos everyone knows Pentium sux.
