Memory

DDR2 Memory Overview

If your computer only has one memory module installed on the system board, you can increase your computer memory by installing an additional memory module.

Your computer supports DDR2 memory. For additional information on the type of memory supported by your computer, see "Specifications."

NOTE: Always install DDR2 memory modules in the order indicated on the system board.

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

• 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.
  
  

NOTE: Memory purchased from Dell is covered under your computer warranty.

NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module. Otherwise, your computer may not start properly.

Drives

Your computer supports a combination of these devices:

• Up to two serial ATA hard drives
  
  
• One FlexBay drive (floppy drive or Media Card Reader)
  
  
• Up to two CD or DVD drives
  
  

1	bay for second hard drive (optional)
2	hard drive
3	FlexBay for optional floppy drive or Media Card Reader
4	CD/DVD 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 "SATA1" 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 Drive 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.

Drive Interface Connectors

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.

1	interface cable
2	interface connector

Power Cable Connector

To connect a drive using the power cable, locate the power input connector on the system board.

1	power input connector
2	power cable

Connecting and Disconnecting Drive Cables

When removing an IDE drive data cable, grasp the colored pull tab and pull until the connector detaches.

When connecting and disconnecting a serial ATA data cable, hold the cable by the black connector at each end.

Like IDE connectors, the serial ATA 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.
