Upgrading Main Memory; Replacing The Processor - Fujitsu D1031 Technical Manual

Upgrading main memory

Four locations (DIMM0 to DIMM3) are available on the system board for main memory. These slots
are suitable for 64, 128, 256 and 512 Mbyte SDRAM memory modules of the DIMM format.
The maximum memory configuration is 2 Gbyte, whereby memory modules with different memory
capacities can be combined.
Equipping must be performed starting with slot 1 (DIMM0) in sequence.
You may only use buffered 3.3V memory modules. Unbuffered memory modules
!
are not permitted.
The SDRAM memory board must be compatible with PC100.
Installing memory modules
Ê
Flip the holders on each side of the relevant location outwards.
Ê
Insert the memory module into the location.
Ê
At the same time flip the lateral holders upwards until the memory module snaps in place.
Removing a memory module
Ê
Flip the holders to the right and left of the location outwards.
Ê
Pull the memory module out of its location.

Replacing the processor

You can replace the processor in the slot of the first processor. The system board can be upgraded
by a second processor if it is inserted into the slot for the second processor.
If the system board only has one processor (inserted into the slot for the first processor ), a
terminating board is installed in the slot for the second processor.
You may only use processors of the same type on the system board (e.g. only Pentium II
!
or only Pentium III). The second processor must have the same clock rate as the first.
A suitable multiprocessor operating system must be used if dual operation is required.
