Memory Installation
The CI7BM Industrial CPU Card supports two three 168-pin DIMM
sockets for a maximum total memory of 768 SDRAMs. A manufacturing
option replaces the DIMM3 socket as 64MB SDRAM memory on board.
The memory modules can come in sizes of 16MB, 32MB, 64MB,
128MB and 256MB SDRAMs.
In populating the DIMM sockets, any of the DIMM banks can be
populated first. Refer to the following table on how to configure the
memory.
NOTE: Use SDRAM modules with PC100 specification when running
100MHz CPU bus speed. With 66MHz CPU bus speed,
SDRAM modules with PC66 or PC100 specification can be
used. You have to install the Pentium II processor before
installing the memory modules.
