Installing Memory Modules - IBM 6219 - IntelliStation M - Pro User Manual

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
2. The DIMM options available for your computer are 128 MB, 256 MB, 512 MB, 1
3. The amount of usable memory will be reduced depending on the system
4. Your computer comes with two 128 MB, 256 MB, or 512 MB DIMMs (for a total
5. DIMMs must be installed in matched pairs. The first pair of DIMMs you install in
6. Install only 133 MHz (memory bus), 2.5 V, 184-pin, double-data-rate (DDR),

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.
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.
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.
1. Review the safety information beginning on page vii, "Installation guidelines" on
page 29, and "Handling static-sensitive devices" on page 29.
2. Remove the side cover (see "Removing the side cover" on page 34).
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 34.)
5. Remove the support bracket (see "Removing and installing the support
bracket" on page 35).
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.
