Working with Memory Modules
Working with Memory Modules
Adding system memory to your server is an easy way to make programs run faster.
You can increase the amount of system memory by installing options called
memory modules
. The server uses a noninterleaved memory configuration, with
error correcting code (ECC) data protection.
Notes:
1. Your server comes with one or more dual-inline memory modules (DIMM)s
installed.
2. The server supports 100 MHz, 64 MB, 128 MB, and 256 MB DIMMs.
3. Install only registered SDRAM ECC DIMMs.
4. When you are installing memory modules, you might find it more efficient to
install them in adjacent connectors, with no vacant memory connectors in
between. For example, if your server only has one DIMM installed in memory
connector J15, install additional memory in the J16 memory connector; then,
continue with connectors J17 and J22.
5. If you are installing DIMMs of different sizes, you might find it more efficient to
install DIMMs with the greater memory capacity starting with connector J15.
For example, when installing two 256 MB DIMMs, install the DIMMs in memory
connectors J15 and J16.
6. After installing or removing a DIMM, you must save the new configuration
information using the Configuration/Setup Utility program. See “Using the
Configuration/Setup Utility” on page 22.
Installing or Removing Memory Modules
This section gives the procedure for installing memory modules. If you want to
remove a memory module, reverse the following steps.
Before you begin
Read “Electrical Safety” on page 41 and “Handling Static-Sensitive Devices”
on page 42.
Read the documentation that comes with the option.
1. If you have not done so, remove the server cover. See “Preparing to Install
Options” on page 43.
2. Locate the memory-module connectors on the system board (see “System
Board Connectors” on page 169).
Notes:
a. Each connector slot contains two keys (dividers), which are used to assure
that a memory-module can be installed only in the correct position.
b. A retaining clip at each end of the connector locks the memory module into
place.
3. Press the retaining clips at the ends of the connector downward to the open
position.
