You can increase the amount of memory in your computer by installing a

double-data-rate three synchronous dynamic random access memory (DDR3

SDRAM)-available as an option-in the memory slot of your computer. DDR3

SDRAMs are available in various capacities.

To install a DDR3 SDRAM, do the following:

Touch a metal table or a grounded metal object to reduce any static elec-

tricity in your body, which could damage the DDR3 SDRAM. Do not

touch the contact edge of the DDR3 SDRAM.

computer.

Note: Use only the memory types supported by your computer. If you incorrectly install

optional memory, or install an unsupported memory type, a warning beep will sound

when you try to start the computer.
