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

your Owner's Manual.

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.

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

NOTICE: Do not install ECC or buffered memory modules. Only unbuffered, non-ECC memory is supported.

NOTE: If you install DDR2 667-MHz memory, the speed is reduced to 533 MHz.

If you install mixed pairs of DDR2 400-MHz (PC2-3200) and DDR2 533-MHz (PC2-4300) memory, the modules function
at the slowest speed installed.

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.

Drives

Your computer supports a combination of these devices:

Up to two serial ATA hard drives
One FlexBay drive (may contain an optional floppy drive or an optional Media Card Reader)

Up to two CD or DVD drives

1 CD/DVD drive(s)
2 FlexBay for optional floppy drive or optional Media Card Reader
3 hard drive(s)

Connect CD/DVD drives to the connector labeled "IDE" on the system board. Serial ATA hard drives should be connected to
the connectors labeled "SATA0" or "SATA2" on the system board.

IDE Drive Addressing

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 master or boot device (drive 0), and the device attached to the
middle connector on the interface cable is the slave device (drive 1). See the drive documentation in your upgrade kit for
information on configuring devices for the cable select setting.

Connecting and Disconnecting Drive Interface Cables

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.

When removing an IDE drive data cable, grasp the colored pull-tab and pull until the connector detaches.
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. Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored
stripe along one edge of the IDE cable—serial ATA cables do not use a colored stripe) goes to the pin-1 end of the connector.
The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1" printed directly on the board or
card.

NOTICE: When you connect an IDE interface cable, do not place the colored stripe away from pin 1 of the connector.

Reversing the cable prevents the drive from operating and could damage the controller, the drive, or both.
