SO-DIMM Upgrade Sockets
The system board has two 168-pin, gold-plated SO-DIMM sockets (locations
are shown on the figure “System Board Internal Connector, Socket, and Jumper
Locations” at the beginning of this section). The sockets support up to 256 MB
of high-speed SDRAM memory. The sockets support SO-DIMM modules in
64-MB and 128-MB unbuffered non-ECC memory configurations.
The SO-DIMM modules
!
can be installed in one or two sockets
!
size can vary between sockets
!
speed must match the processor bus speed (100 MHz)
!
can be single- and double-sided.
See the following tables for supported SO-DIMMs and for sample SO-DIMM
upgrade paths. To determine the memory needed for a memory upgrade, see the
paragraph following the tables. To remove or install a SO-DIMM, see Section 3,
“Disassembly and Reassembly.”
