Double Data Rate 3 (DDR3) is a type of DRAM (dynamic random-access memory) used in computers

Double Data Rate type 3 (DDR3) is the current dominant type of RAM which surpassed the formerly most popular DDR2 RAM in the last couple of years.

Is a DDR3 MB compatible with DDR2 RAM?

If a motherboard's specifications say it supports DDR3 SDRAM sticks, would I be correct to assume it is also compatible with DDR2 RAM? Am I wrong, or does it depend on the motherboard?
