Memory Installation
The P/I-P3BVL Industrial CPU Card supports three 168-pin DIMM
sockets for a maximum total memory of 384MB unregistered
SDRAMs or 768MB registered SDRAMs. The memory modules can
come in sizes of 16MB, 32MB, 64MB, 128MB and 256MB (for
registered type) SDRAMs.
The P/I-P3BVL Industrial CPU Card supports three 168-pin DIMM
(Dual In-line Memory Module) sockets. In populating the DIMM
sockets, DIMM1 and/or DIMM3 bank should be populated first for
less signal reflection. However, we do not see any issue while
populate DIMM2 only. 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.
