Replacing the memory module
Before you start, print these instructions.
Increasing memory capacity is an effective way to make programs run faster. You can increase the amount
of memory in your computer by installing a a double data rate three (DDR3) synchronous dynamic random
access memory (SDRAM) unbuffered small outline dual inline memory module (SO-DIMM), available as an
option, in the memory slot of the computer.
When replacing the memory, be sure to follow the precautions.
Note: The operating speed of the memory module has dependency on the system conguration. In some
conditions, the memory in your computer might not be able to operate at the maximum speed.
Attention: Before you start installing a memory module, touch a metal table or a grounded metal object. This
action reduces any static electricity from your body. The static electricity could damage the memory module.
Use a PC3-12800 DDR3 synchronous DRAM unbuffered memory module in your computer. If you install a
memory module that is not supported by your computer, the computer might beep, and the system might
not start or might not work properly. You can purchase the appropriate memory option from your Lenovo
reseller or a marketing representative.
