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, 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 upper-right corner of the module to determine the
module's capacity.
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
lIf you install mixed pairs of DDR2 400-MHz (PC2-3200) and DDR2 533-MHz (PC2-4200) memory, the modules function at the slowest speed installed.
Similarly, if you install memory modules with mixed CAS Latency (CL) rates, the modules function at the speed and CAS latency capabilities of the
slowest DIMM.
lBe sure to install a single memory module in DIMM connector 1, the connector closest to the processor, before you install modules in the other
connectors.
NOTE: Always install DDR2 memory modules in the order indicated on the system board.
NOTICE: Do not install ECC memory modules.


Addressing Memory With 4-GB Configurations
Your computer supports a maximum of 4 GB of memory when you use four 1-GB DIMMs. Current operating systems, such as Microsoft®Windows®XP, can
only use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is less than 4 GB. Certain components
within the computer require address space in the 4-GB range. Any address space reserved for these components cannot be used by computer memory.


Drives
Your computer supports a combination of these devices:
lUp to two hard drives
lOne optional floppy drive
lUp to two CD or DVD drives

General Installation Guidelines
Connect serial ATA hard drives and serial CD/DVD drives to the system board connectors labeled SATA-0, SATA-1, SATA-2, or SATA-3. Connect IDE CD/DVD
drives to the connector labeled PRI IDE.
When you connect two IDE devices to a single IDE interface cable and configure them for the cable select setting, the device attached to the last connector on
the interface cable is the primary or the boot device (drive 0), and the device attached to the middle connector on the interface cable is the secondary device
(drive 1). See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting.

Connecting Drive Cables
NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the computer. The brackets also keep dust
and dirt out of your computer.
NOTICE: To connect a network cable, first plug the cable into the network device and then plug it into the computer.

When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board. Some drives may
also have an audio connector; one end of the audio cable attaches to the drive connector and the other end attaches to the system board.

Drive Interface Connectors
Serial ATA Connector
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other
connector.
When you connect an IDE cable, ensure that you align the colored stripe with the pin 1 connector. When you disconnect an IDE cable, grasp the colored pull
tab and pull until the connector detaches.
When you connect and disconnect a serial ATA cable, hold the cable by the connector at each end.

Hard Drive 


1. If you are replacing a hard drive that contains data you want to keep, back up your files before you begin to remove the hard drive.

2. Follow the procedures in "Before You Begin."

Removing a Hard Drive

1. Disconnect the power and data cable from the drive and from the system board.
NOTE: The system board serial ATA connector may have an attached cover or shroud.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.
NOTICE: To avoid damage to the drive, do not set it on a hard surface. Instead, set the drive on a surface, such as a foam pad, that will sufficiently
cushion it.


2. Press in on the tabs on each side of the drive and slide the drive up and out.

Installing a Hard Drive

1. Unpack the replacement hard drive, and prepare it for installation.

2. Check the documentation for the drive to verify that it is configured for your computer.

3. If your replacement hard drive does not have the bracket rails attached, remove the rails from the old drive by removing the two screws that secure
each rail to the drive. Attach the bracket rails to the new drive by aligning the screw holes on the drive with the screw holes on the bracket rails and
then inserting and tightening all four screws (two screws on each rail).

4. Install the hard drive into the computer by gently sliding the drive into place until you hear it securely click.

5. Connect the power and data cable to the drive and to the system board.
