System memory is stored in SDRAM that is of the DDR3 variety. Both the DRAM and SO-DIMM form factors are offered for it.

Similar to DDR2 RAM, DDR3 RAM uses about 30% less electricity and has twice the data transmission speed. DDR3 memory enables highest data transmission speeds of 6400 MBps, whereas DDR2 memory is only capable of 3200 MBps (megabytes per second). In comparison to DDR2 systems, computers with DDR3 memory can transport data to and from the Processor much more quickly. Bottlenecks are avoided thanks to the quicker memory performance, particularly when handling significant quantities of data. The computer with DDR3 memory may therefore operate more quickly than the computer with DDR2 memory if the two computers have the same CPU processing speed but different kinds of memory.

DDR3 memory modules have a similar appearance to DDR and DDR2 processors, but they vary in that there is a distinct space between the two pairs of wires on the underside of each module. As a result, the RAM component cannot be inserted into a spot that is incompatible with DDR3 RAM. As a result, when updating the memory in your machine, be careful to buy the right kind of memory.
