System Board 4-7
SO-DIMM Upgrade Sockets
The system board has two 168-pin, gold-plated SO-DIMM sockets. (See the
figure “System Board Internal Connector, Socket, and Jumper
Locations - Side 1” for socket locations.) 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.”
