|Internal memory type||DDR3|
|Memory clock speed||1600 MHz|
|Memory voltage||1.5 V|
|Memory form factor||204-pin SO-DIMM|
|Internal memory||4 GB|
|Memory layout (modules x size)||1 x 4 GB|
In short, 204-pin small outline dual inline memory modules (SODIMMs) are the form factor used to provide DDR3 memory modules for notebook computers and other small form factor computing platforms. 204-pin SODIMMs are currently available in PC3-8500 (DDR3 1066MHz) and PC3-10600 (DDR3 1333MHz) speeds.
To use DDR3 memory, your system must have both a 204-pin SODIMM slot and a chipset that supports DDR3 memory. A DDR3 SODIMM will not fit into DDR2 or DDR memory sockets.
