DDR2 DIMMs are not designed to be backwards compatible with DDR DIMMs. The notch on DDR2 DIMMs is in a different position than DDR DIMMs, and the pin density is slightly higher than DDR DIMMs in desktops. DDR2 is a 240-pin module, DDR is a 184-pin module.

I do not accept some of the claims as to how much faster, but it is a big difference.
Your mother board must support the 240 pin DDR2 module for you to use DDR2.
