Memory
You can increase your computer memory by installing memory modules on the system board.
Your computer supports unbuffered, non-ECC, DDR2 memory.
NOTE:
Buffered memory is not supported on this computer.
DDR2 Memory Overview
DDR2 memory modules should be installed in
pairs of matched memory size, speed, and technology
. If the
DDR2 memory modules are not installed in matched pairs, the computer will continue to operate, but
with a slight reduction in performance. See the label on the module to determine the module’s capacity.
NOTE:
Always install DDR2 memory modules in the order indicated on the system board.
