DDR 1 ranges from PC1600 up to PC4000 those modules have 184pins,DDR2 uses 240 pins and Ranges from PC2-4200 up to PC2-8000 i believe they may go higher...main difference is speed and platform for amd u must have a am2 motherboard to run ddr2 intel i believe ddr2 started with the pentium 4 ht cpus with the 800fsb...laptops those are a whole different story because use there own type of module called a SO-DIMM

uh..no...

laptops use so-dimm yes, but there is such thing as ddr1 so-dimm and ddr2 so-dimm.

I believe he was just saying that laptops have their own seperate module, not that there were ddr sodimm and ddr2 sodimm...

But, back to the point. DDR2 is supposed to "theoretically" suposed to deliver more bandwidth than DDR can.

Here's a review I came across on google. http://www.xbitlabs.com/articles/memory/display/ddr2-ddr.html
