Memory

You can increase your computer memory by installing memory modules on the system board. For information on the type of memory supported by your computer, see Memory .

Memory Overview

l

Memory modules should be installed in pairs of matched memory size, speed, and technology for best performance. Otherwise, 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.

1 memory module 2 memory module capacity label

NOTE:

Always install memory modules in the order indicated on the system board.

The recommended memory configurations are:

or

¡

A pair of matched memory modules installed in connectors DIMM_1 and DIMM_2 l l l

¡

A pair of matched memory modules installed in connectors DIMM_1 and DIMM_2 and another matched pair installed in connectors DIMM_3 and

DIMM_4

If you install mixed pairs of DDR2 533-MHz (PC2-4300), DDR2 667-MHz (PC2-5300), and DDR2 800-MHz (PC2-6400) memory, the modules function at the slowest speed installed.

Be sure to install a single memory module in the DIMM_1 connector, the connector closest to the processor, before you install modules in the other connectors.

While installing memory modules, ensure that you do not mix ECC and non-ECC memory.

1 Channel A: matched pair of memory modules in connectors DIMM_1 and

DIMM_2 (white securing clips)

2 Channel B: matched pair of memory modules in connectors DIMM_3 and

DIMM_4 (black securing clips)

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 connectors DIMM_1 and DIMM_2 or connectors DIMM_3 and DIMM_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 only 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.
