1.6 Memory Upgrade
The three 168-pin sockets onboard supports SDRAM-type DIMMs only.
You may install 16-MB, 32-MB, 64-MB, or 128-MB DIMMs for a
maximum 384-MB system memory.
The SDRAM DIMMs should work under 3.3 volts; 5-volt memory devices
are not supported. Memory modules with a timing setting of 66 MHz
are defined under unbuffered DIMM specifications, while 100 MHz
modules are defined under Intel PC-100 SDRAM specifications.
Do not use both 66 MHz (unbuffered) and 100
MHz (registered) SDRAM together. This might
cause your system to malfunction.
Each of the sockets represents one independent bank. This allows you
to install DIMMs with different capacities to form a configuration.

1.6.1 Memory Configurations

Table 1-3 lists some system memory configurations. You may combine
DIMMs with various capacities to form other combinations.
