Upgrading main memory
The system board is equipped with two 168 pin sockets with which the main memory can be
upgraded to a maximum of 256 Mbyte.
These slots are suitable for 16, 32, 64 and 128 Mbyte SDRAM memory modules of the DIMM
format.
Memory modules with different memory capacities can be combined.
DIMM = Dual Inline Memory Module
SDRAM = Synchronous Dynamic Random Access Memory
!
Depending on the processor type SDRAM memory modules must be designed for a
clock frequency of 66 MHz or 100 MHz or higher (meets PC100 specification).
