  Removing and Replacing Memory Modules


Your computer uses 1066 MHz or 1333Mhz DDR3 unbuffered SDRAM memory. DDR3 SDRAM, or double-data-rate three synchronous dynamic random access memory, is a random access memory technology. It is a part of the SDRAM family of technologies, which is one of many DRAM (dynamic random access memory) implementations, and is an evolutionary improvement over its predecessor, DDR2 SDRAM.
