5.Unscrew the mounting bracket of the card you want to remove.

6.Grasp the card by its outside corners, and ease it out of its connector.

7.If you are removing the card permanently, install a metal filler bracket over the empty card-slot opening.

NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of your computer.

8.Replace the expansion-card cage in the chassis as instructed in "Replacing the Expansion-Card Cage."

9.Replace the computer cover, and reconnect your computer and peripherals to their electrical outlets and turn them on.

NOTE: If Enabled, the Chassis Intrusion option will cause the following message to be displayed at the next system start-up:

ALERT! Cover was previously removed.

Adding Memory

Memory can be increased to a maximum of 768 megabytes (MB) by installing combinations of 32-, 64-, 128-, or 256-MB dual in-line memory modules (DIMMs) in the three DIMM sockets on the system board. Figure 6 shows the DIMMs and DIMM sockets.

Your system can support both error checking and correction (ECC) and nonparity synchronous dynamic random-access memory (SDRAM) DIMMs. However, ECC support is available only if all DIMMs are ECC DIMMs. ECC DIMMs enable your system to correct all single-bit memory errors and detect multibit memory errors.

When you add system memory, you may install DIMMs in any socket. For optimum operation, Dell recommends that you install a DIMM in socket A first (closest to the processor) before installing a DIMM in another socket.
