3. Unscrew and remove the filler bracket for the card slot you want to use. Save the screw to use when installing the expansion card later in this
procedure (see
Figure 19 ).
4. Align the cutout on the bottom of the card with the crossbar in the system board connector. Gently rock the card into the connector until it is fully seated
(see
Figure 19 ).
If the card is full-length, insert the front end of the card into the corresponding card guide at the front of the system as you insert the card into its
connector.
5. Secure the bracket on the end of the card with the screw you removed in step 3.
6. Connect any cables required for the card as described in the card documentation.
7. Replace the system cover and support beam.
8. Plug your system and devices into their electrical outlets, and turn them on.
9. Install any drivers required for the card as described in the card documentation.
Memory Modules
The four memory module sockets on the system board can accommodate 64 MB to 2 GB of registered SDRAM (see Figure 18 ).
System Memory Upgrade Kits
The system is upgradable to 2 GB by installing combinations of 64-, 128-, 256-, and 512-MB registered memory modules. If you receive an error message
stating that maximum memory has been exceeded, see "
Codes and Error Messages ." You can purchase memory upgrade kits as needed.
Memory Module Installation Guidelines
For optimum operation, install the memory modules starting with the DIMM_A socket (furthest from the microprocessor) and working toward the DIMM_D
socket, leaving no open sockets between installed memory modules.
Figure 20. DIMM Socket Locations
Table 2 illustrates several sample memory configurations based on these guidelines.
Table 2. Sample DIMM Configurations
Performing a Memory Upgrade
To perform a memory upgrade to the system board, perform the following steps.
1. Turn off the system, including any attached peripherals, and disconnect the power cord from its power source.
2. Remove the system cover .
3. Locate the memory module sockets in which you will install or replace memory module pairs.
CAUTION: Read the safety instructions in your System Information document.
NOTE: The memory modules must be PC-133 compliant.
