Memory Modules
The four memory module connectors on the system board can accommodate from 128 MB to 4 GB of registered memory modules.
Memory Upgrade Kits
System memory is upgradable to 4 GB by installing combinations of 128-, 256-, 512-MB, and 1-GB registered DDR SDRAM modules. You can purchase memory
upgrade kits as needed.
Memory Module Installation Guidelines
Starting with the connector nearest the side of the system board, the memory module sockets are labeled "DIMMA" through "DIMMD" (see
Figure A
-3
). When
you install memory modules, install the first module in connector DIMMA before installing additional modules in connectors DIMMB, DIMMC, and DIMMD.
Table 6
-1
lists sample memory configurations based on these guidelines.
Table 6-
1. Sample Memory Module Configurations
Performing a Memory Upgrade
1.
Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2.
Remove the cover (see "
Removing the Cover
" in "Troubleshooting Your System").
3.
Lay the system on its right side.
4.
Install or remove memory modules as necessary to reach the desired memory total (see "
Installing Memory Modules
" and "
Removing Memory
Modules
").
See
Figure A
-3
to locate the memory module connectors.
5.
Stand the system upright.
6.
Install the cover (see "
Installing the Cover
" in "Troubleshooting Your System").
7.
Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
After the system completes the POST routine, it runs a memory test.
NOTICE:
The DDR SDRAM memory modules must be PC-266 compliant.
