Removing Memory Module
1
Disconnect power from the system
workstation on its side with the system board facing up.
CAUTION
To ensure that memory modules are not damaged during removal or installation, power off
the workstation and unplug the power cord from the AC power outlet. Wait until the LED on the back of
the power supply turns off before removing memory. If you do not unplug the power cord while installing
memory, your memory modules might be damaged and the system will not recognize the memory
changes.

Gently push outwards on the socket levers.
3
Lift the DIMM straight up and remove it from the unit.
NOTE
DIMMs and the DIMM sockets are keyed for proper installation. Be sure these guides line up
when installing a DIMM.
To install a memory module, reverse the previous steps and follow the guidelines in the next section.
Installing Memory Module
You must load memory modules in valid configurations:
Load DDR SDRAM as matched pairs. For example, if you place a memory module of 1 GB in slot 1,
you must also insert a 1-GB module in slot 2.
Load the memory module pairs in order of size, from smallest to largest, beginning with memory
module pair A (closest to PCI slots). For example, if you have 3.5 GB of memory composed of two
256-MB modules, two 512-MB modules and two 1-GB modules, load the 256-MB modules in
memory module pair A, the 512-MB modules in pair B, and the 1-GB modules in memory module pair
C.
Install the DIMM in socket 1 if only installing one DIMM.
