Installing memory
The computer has three connectors for installing dual in-line memory modules
(DIMMs) that provide up to a maximum of 512 MB of system memory.
Installing and removing DIMMs
When installing DIMMs, the following rules apply:
v Fill each system memory connector sequentially, starting at DIMM 1
v Use 3.3 V, synchronous, 168-pin, unbuffered, 133 MHz nonparity synchronous
dynamic random access memory (SDRAM)
v Use 64 MB, 128 MB, or 256 MB DIMMs in any combination
v DIMM heights of 38.1 mm (1.5 inches)
To install a DIMM:
1. Remove the cover. See "Removing the cover" on page 23.
2. You might have to remove an adapter to gain access to the DIMM slots. See
"Installing and removing adapters" on page 27.
