Installing Memory Modules
Supports SDRAM memory. Does not support EDO memory or buffered
DDR-DIMM memory. Memory can be installed in either socket. Memory
size can vary between sockets. DDR-DIMMs can be single- or double-
sided.

Choose the size of the memory module and configuration as shown
in the following table. Memory modules can vary in size and speed
between sockets. The minimum memory size is 128 MB. The
maximum memory size is 1 GB. The BIOS automatically detects the
type, size and speed of the memory modules.
2
Remove the side panel (see “Removing the Side Panel” on page 24).
3
Remove the power supply (see “Removing the Power Supply” on
