Installing memory - desktop model
Your computer has two connectors for installing dual in-line memory modules
(DIMMs) that provide up to a maximum of 512 MB of system memory.
Installing 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 32 MB, 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 - desktop model” on page 34.
