You can increase your computer memory by installing memory modules on the system board. For information on the type of memory supported by your
computer, see "Memory."
NOTE: DDR 333 memory operates at 320-MHz when used with an 800-MHz front-side bus processor.

DDR Memory Overview

DDR memory modules should be installed in pairs of matched memory size. This means that if you purchased your computer with 256 MB of memory installed
and you want to add another 256 MB of memory, you must install it in the appropriate connector. If the DDR memory modules are not installed in matched
pairs, the computer will continue to operate, but with a slight reduction in performance.
NOTE: Always install DDR memory modules in the order indicated on the system board.
The recommended memory configurations are:
A pair of matched memory modules installed in connectors DIMM1 and DIMM2
l
or
A pair of matched memory modules installed in connectors DIMM1 and DIMM2 and another matched pair installed in connectors DIMM3 and DIMM4
l
Additional memory recommendations include:
Do not install ECC memory modules.
l
Be sure to install a single memory module in DIMM 1 or the connector closest to the processor before you install modules in the other connectors.
