Memory Board
The memory board comes already installed with the basic system. A
total of 16 168-pin DIMM sockets reside on the board. The sockets
accept 64-MB, 128-MB, and 256-MB DIMMs for a maximum of 4 GB
memory configuration. The Memory Control Interface consists of one
RAS/CAS Generator (RCG) and two Data Path Multiplexer (MUX)
chipsets which belong to the Intel 450NX chipset.
Each of the sockets represents one independent bank, which allows
you to install DIMMs with different capacities to form a configuration.

Memory Configurations
Every four slots of memory (slot 1-4, 5-8, 9-12, and 13-16) forms a 4-
way interleaving group. You must configure four identical EDO/ECC
buffered DIMMs in a group for your system to work properly. Please
contact your dealer for a list of qualified DIMMs. Use of non-qualified
DIMMs may cause your system to malfunction.
The table below shows the working memory configurations.
