Memory Upgrade Module
Your notebook has two memory slots, and the system comes with 1 GB, 2 GB, or 4 GB of factory-installed
memory. If you have a module installed in only one slot, you can increase your memory capacity by
installing another memory module in the empty slot or by increasing the size of the single installed
module. In order to optimize the dual-channel design, modules of equal capacity should be used. The
minimum amount of memory in your system is 1GB.
Your notebook supports dual-channel memory, which can have a significant effect upon your system’s
performance. In order to support dual-channel memory, two DIMM modules must be installed in your
computer.
