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, look under "Memory" in "Technical Specifications."
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 the new modules were purchased from Dell. Your original
memory modules must be installed as a pair in either connectors RIMM1 and
RIMM2 or RIMM3 and RIMM4. Do not pair one original memory module
with one new memory module in connectors RIMM1 and RIMM2 or RIMM3
and RIMM4. Otherwise, your computer may not start properly.
RDRAM technology requires that all memory connectors have either a memory module or a continuity module installed. Memory modules and continuity modules are easily identified—memory modules have a metal cover on one side of the module and continuity modules do not.
HINT: The metal cover
on a memory module is
manufactured in various
colors. The color of the
metal cover has no effect
on the module's
performance.
Memory modules are the actual components that provide memory for the microprocessor; continuity modules are used only to complete the memory circuit if memory modules are not installed in all of the memory connectors.
Another RDRAM requirement is that memory modules must be installed in pairs of matched memory size. This means that if you purchased your computer with 128 MB of memory installed and you want to add another 128 MB of memory, you must remove the two continuity modules and replace them with two 64-MB memory modules.
NOTICE: You can only install continuity modules in connectors RIMM3 and
RIMM4.
HINT: Mixed pairs of
PC1066 and PC800
modules all function as
PC800.
The only two valid memory configurations are:
A pair of matched memory modules installed in connectors RIMM1 and RIMM2 with continuity modules installed in connectors RIMM3 and RIMM4
or
A pair of matched memory modules installed in connectors RIMM1 and RIMM2 and another matched pair installed in connectors RIMM3 and RIMM4
HINT: Memory
purchased from Dell is
covered under your
computer warranty.
Press out the securing clip at each end of the memory module
connector.
Align the notch on the bottom of the module with the crossbar in the
connector.
NOTICE: To avoid damage to the memory module, press the module straight
down into the socket with equal force applied at each end of the module.
Insert the module straight down into the connector, ensuring that it
fits into the vertical guides at each end of the connector. Press firmly
on the ends of the module until it snaps into place.
If you insert the module correctly, the securing clips snap into the cutouts at each end of the module.
