AOpen DX2G Plus System Board

Memory Upgrade
The four 168-pin sockets onboard support SDRAM-type DIMMs. You
may install 16-MB, 32-MB, 64-MB, 128-, 256-, or 512-MB (single and
double density) DIMMs for a maximum of 2048-MB system memory.
The SDRAM DIMMs should work under 3.3 volts only; 5-volt memory
devices are not supported. AOpen DX2G Plus supports both 100MHz
standard and registered SDRAM. However, they cannot be used at
the same time in a system. Please contact your dealer for qualified
DIMM vendors.
Do not use both 100 MHz (registered) and 66
MHz (standard/unbuffered) SDRAM together.
Such a combination might cause your system
to malfunction.
Each of the DIMM sockets is independent from the others. This
independence allows you to install DIMMs with different capacities to
form different configurations.
1.7.1
Memory Configurations
Table 1-3 lists some system memory configurations.
You may
combine DIMMs with various capacities to form other combinations.
