Working with memory
You can add memory to your computer to increase system performance.
Your computer has two connectors for installing memory modules that
provide up to a maximum of 512 MB of system RAM.
Your computer uses dual inline memory modules (DIMMs). The
IBM-installed DIMMs that come with your computer are unbuffered,
synchronous dynamic random access memory (SDRAM).
When installing or replacing DIMMs, the following rules apply:
Ÿ
Fill each system memory connector sequentially, starting at DIMM 0.
Ÿ
Use only 3.3 V, 100 MHz, unbuffered, SDRAM DIMMs
Ÿ
Use only 32, 64, 128, or 256 MB DIMMs in any combination of
supported SDRAM DIMMs.
Note: To locate the memory connectors on the system board, see
“Identifying parts on the system board” on page 64.
Before you begin:
Ÿ
Read “Safety information” on page vii and “Handling
static-sensitive devices” on page 53.
Ÿ
Read the instructions that come with the new system memory.
Ÿ
Turn off the computer and all other connected devices.
Ÿ
Disconnect all cables attached to the computer and remove the
computer cover (see “Removing the cover — tower model” on
page 56).
Ÿ
Read “Accessing the system board” on page 64 to learn the
location of the parts on the system board.
To install a DIMM:
1. You may need to remove the power supply to gain access to the DIMM
sockets. See “Moving the power supply— desktop model” on page 59
or “Moving the power supply—tower model” on page 61.
2. If you have an adapter that is 8 inches or more in PCI slot 1, you may
have to remove the adapter to access the DIMM sockets.
a. Remove the retaining screw from the adapter slot cover.
b. Remove the adapter.
