Memory
You can increase your computer memory by installing memory modules on the system board.
Your computer supports DDR2 memory. For additional information on the type of memory supported by your computer, see Memory.
DDR2 Memory Overview
DDR2 memory modules should be installed in pairs of matched memory size and speed. 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 upper-right or upper-left 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 DIMM connectors 1 and 2
or
A pair of matched memory modules installed in DIMM connectors 1 and 2 and another matched pair installed in DIMM connectors 3 and 4
NOTICE: Do not install ECC memory modules.
If you install mixed pairs of PC2-4300 (DDR2 533-MHz) and PC2-5300 (DDR2 667-MHz) memory, the modules function at the speed of the slowest module installed.
Be sure to install a single memory module in DIMM connector 1, the connector closest to the processor, before you install modules in any other connector.

About Serial ATA Drives
Your computer supports up to four serial ATA hard drives and two serial ATA optical drives. Serial ATA drives provide the following benefits by transferring data using serial technology and flexible cables that are thinner and longer than IDE cables:
Improved cable routing facilitates more efficient airflow inside the chassis.
Compact cable connectors save space on the system board and on the hard drive, allowing for more efficient utilization of space inside the chassis.
General Drive Installation Guidelines
The system board does not differentiate between HDD and "other" SATA ports. SATA HDD drives are connected to the same SATA ports as all other SATA based devices in the system including the optical drives. SATA hard drives should be attached to the connectors labeled SATA beginning with SATA port 0. When adding additional SATA devices to the system, use the first available SATA port following the last SATA HDD. IDE CD/DVD drives should be connected to the connectors labeled "IDE."
When connecting a SATA cable, hold the cable by the connector at each end and press firmly into the connector. When disconnecting a SATA cable, hold the cable by the connector at each end and pull until the connector detaches.
