DDR2 Memory Overview
Dual-channel DDR2 memory modules should be installed in pairs of matched memory size. If the DDR2 memory modules are not installed with the same
amount of memory in each channel, the computer will continue to operate, but with a slight reduction in performance. See the label in the upper-right corner of
the module to determine the module's capacity.
NOTE:
Always install DDR2 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 memory module installed in connector DIMM1
l
or
For the mini tower, desktop, and small form factor computers, a pair of matched memory modules installed in connectors DIMM1 and DIMM2 and another
l
matched pair installed in connectors DIMM3 and DIMM4
NOTICE:
Do not install ECC memory modules. Doing so may cause the system not to boot or affect performance.
Be sure to install a single memory module in DIMM1, the connector closest to the processor, before you install modules in the other connectors.
NOTE:
The ultra small form factor computer has only two slots which are considered an interleaved pair. The mini tower, desktop, and small form factor
computers have four slots.
