DIMM Sockets

The system board has two, 168-pin, gold-plated DIMM sockets (locations are
shown on the figure at the beginning of this section). The sockets support up to
512 MB of high-speed SDRAM memory. The sockets support DIMM modules
in 32-, 64-, 128-, and 256-MB 66-MHz and 100-MHz non-ECC memory
configurations.
Use these guidelines when selecting DIMMS:
T
DIMMs can be installed in one, or two sockets
T
DIMM size can vary between sockets
T
DIMM speed must match the processor bus speed (66 MHz or 100 MHz)
T
Single- and double-sided DIMMs can be mixed.
See the following tables for supported DIMMs and for sample DIMM upgrade
paths. To determine the memory needed for a memory upgrade, see "Checking
System Memory."
To remove or install a DIMM, see Section 3, "Disassembly and Reassembly."
