See Figure A-3 for the location of the four memory module connectors. The four memory module connectors on the system board can accommodate from 256 MB to 4 GB of 400/533-MHz unbuffered ECC DDR II memory modules.
Memory Module Upgrade Kits
The system is upgradable to 4 GB by installing combinations of 256-MB, 512-MB, or 1-GB 400-MHz or 533-MHz unbuffered ECC DDR II memory modules. You can purchase memory upgrade kits from Dell.
Memory Module Installation Guidelines
If only one memory module is installed, it must be installed in connector DIMM_1.
If only one memory module is installed in connector DIMM_1, its capacity must be 256 MB.
If more than one memory module is installed, the memory modules should be installed in pairs of matched memory size, speed, and technology.
Memory modules should be installed in ordered pairs in connectors DIMM_1 and DIMM_2, and then DIMM_3 and DIMM_4.
NOTICE: If you remove your original memory modules from the system during a memory upgrade, keep them separate from any new memory modules that you may have, even if you purchased the new memory modules from Dell. Use only unregistered or unbuffered ECC DDR II memory modules.
Addressing Memory With 4-GB Configurations (Microsoft® Windows® Only)
Your system supports a maximum of 4 GB of memory using four 1-GB memory modules. Current operating systems can use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is slightly less than 4 GB.
NOTE: Depending on the type of PCI/PCIe expansion cards that are installed in your system, your system may only support a maximum of 3.4 GB of memory or less.
Certain components within the system require address space in the 4-GB range. Any address space reserved for these components cannot be used by system memory.
Integrated PCI devices (such as NICs) and SCSI controllers
PCI expansion cards
At start-up, the BIOS identifies the components that require address space. The BIOS dynamically calculates the amount of reserved address space required. The BIOS then subtracts the reserved address space from 4 GB to determine the amount of usable space.
If the total installed system memory is less than the usable space, all installed system memory is available for use only by the operating system.
If the total installed system memory is equal to or greater than the usable address space, a small portion of installed memory is available for use by the operating system.
Installing a Memory Module
CAUTION: See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.
Turn off the system and attached peripherals, and disconnect the system from the electrical
outlet.
Open the system. See "Opening the System" in "Troubleshooting Your System."
Press on the securing clip at each end of the memory module connector. See Figure 6-3.
Align the memory module's edge connector with the alignment key in the connector.
The memory module connector has an alignment key that allows the memory module to be installed in the connector in only one way.
Insert the module into the connector, and carefully press each end of the module into place.
Figure 6-3. Installing a Memory Module
Pull up on the securing clips to lock the module into place.
If you insert the module correctly, the securing clips snap into the cutouts at each end of the module.
