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 1 GB of system SDRAM.
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:
Fill each system memory connector sequentially, starting at DIMM 0.
Use only 3.3 V, 133 MHz, unbuffered, SDRAM DIMMs.
Use only 64, 128, 256, or 512 MB DIMMs in any combination of
supported SDRAM DIMMs.
Note:
To locate the memory connectors on the system board, see the
system board label inside your computer.
Before you begin:
Read “Safety information” on page ix and “Handling
static-sensitive devices” on page 61.
Read the instructions that come with the new system memory.
Turn off the computer and all other connected devices.
Disconnect all cables attached to the computer and remove the
computer cover (see “Removing the cover — tower model” on
page 68 or “Removing the cover — desktop model” on page 64).
Read “Accessing the system board” on page 74 to learn the
location of the parts on the system board.
Notes:
1. You might need to remove the power supply to gain access to the
DIMM sockets. See “Moving the power supply — desktop model” on
page 66 or “Moving the power supply — tower model” on page 71.
2. You might have to remove an adapter to access the DIMM sockets.
