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 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 DIMM connectors 3 and 4

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.

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. You should install your original memory modules in pairs either in DIMM connectors 1 and 2 or DIMM connectors 3 and 4.

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 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.

Removing Memory

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.
  1. Follow the procedures in "Before You Begin."

  2. Remove the computer cover.

  3. Press out the securing clip at each end of the memory module connector.

  4. Grasp the module and pull up.

If the module is difficult to remove, gently ease the module back and forth to remove it from the connector.

  5. Click the General tab.

  6. To verify that the memory is installed correctly, check the amount of memory (RAM) listed.


Cards

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.

Your Dell™ computer provides the following slots for PCI and PCI Express cards:

  • Two PCI card slots

  • One PCI Express x16 card slot

  • One PCI Express x1 card slot

PCI Cards

Your computer supports two PCI cards.

If you are installing or replacing a card, follow the procedures in the next section. If you are removing but not replacing a PCI card, see "Removing a PCI Card."

If you are replacing a card, remove the current driver for the card from the operating system.

If you are installing or replacing a PCI Express card, see "Installing a PCI Express Card."

Installing a PCI Card

  1. Follow the procedures in "Before You Begin."

  2. Remove the computer cover.

card retention door

  1. Gently push the release tab on the card retention door from the inside to pivot the door open. Because the door is captive, it will remain in the open position.

  2. If you are installing a new card, remove the filler bracket to create a card-slot opening. Then continue with step 6.

  3. If you are replacing a card that is already installed in the computer, remove the card.

If necessary, disconnect any cables connected to the card. Grasp the card by its top corners, and ease it out of its connector.

  1. Prepare the card for installation.

See the documentation that came with the card for information on configuring the card, making internal connections, or otherwise customizing it for your computer.

CAUTION: Some network adapters automatically start the computer when they are connected to a network. To guard against electrical shock, be sure to unplug your computer from its electrical outlet before installing any cards.
  1. Place the card in the connector and press down firmly. Ensure that the card is fully seated in the slot.

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.
