Installing memory modules
You can increase the amount of memory in your computer by installing memory
modules. Your IntelliStationM Pro computer uses industry-standard PC2100
double-data-rate (DDR) dual inline memory modules (DIMMs).
Notes:
1. The system board contains four DIMM connectors and supports two-way
memory interleaving.
2. The DIMM options available for your computer are 256 MB, 512 MB, and 1 GB .
Your computer supports a minimum of 256 MB and a maximum of 4 GB of
system memory.
3. The amount of usable memory will be reduced depending on the system
configuration. A certain amount of memory must be reserved for system
resources. The BIOS code will display the total amount of installed memory and
the amount of configured memory.
4. Your computer comes with two 128 MB, 256 MB, or 512 MB DIMMs (for a total
of 256 MB, 512 MB, or 1024 MB) installed in the DIMM 1 and DIMM 2 memory
connectors. When you install additional DIMMs, be sure to install them as a pair
in DIMM connectors 3 and 4.
5. DIMMs must be installed in matched pairs. The first pair of DIMMs you install in
DIMM 1 and 2 memory connectors must be the same size, speed, type, and
technology. You can mix compatible DIMMs from various manufacturers. If you
install a second pair of DIMMs in DIMM 3 and DIMM 4 memory connectors,
they do not have to be the same size, speed, type, and technology as the
DIMMs you installed in DIMM 1 and DIMM 2 memory connectors. However, the
size, speed, type, and technology of the DIMMs you install in DIMMs 3 and
DIMM 4 memory connectors must match each other.
6. Install only 133 MHz (memory bus), 2.5 V, 184-pin, double-data-rate (DDR),
PC2100, unbuffered synchronous dynamic random-access memory (SDRAM)
with error correcting code (ECC) DIMMs. These DIMMs must be compatible
with the latest PC2100 SDRAM unbuffered DIMM specification. For a list of
supported options for your computer, go to http://www.ibm.com/pc/ on the World
Wide Web; then, select your country and navigate to the list of options for your
computer.
Complete the following steps to install a DIMM:
1. Review the “Important safety information” on page iii, “Installation guidelines”
on page 35, and “Handling electrostatic discharge-sensitive devices” on
page 110.
2. Remove the side cover (see “Removing the side cover” on page 41).
3. Turn off the computer and all attached devices.
4. Disconnect all external cables and power cords; then, remove the side cover
(see “Removing the side cover” on page 41.)
5. Remove the support bracket (see “Removing and installing the support
bracket” on page 41).
6. To make it easier to install memory modules, rotate the drive cage out of the
computer. Grasp the drive cage and rotate it until it locks into place.
7. Locate the DIMM connectors on the system board. Determine the connectors
into which you will install the DIMMs.
8. Open the retaining clips and, if necessary, remove any existing DIMM.
