Upgrading Main Memory - Siemens Fujitsu D1159 Manual

Remove the old processor if necessary.


Slide the processor into the bracket (1).


Push the processor down in the bracket and press it into the slot until the clamps (2) to the left
and right snap into place.


If the processor has a temperature sensor or a fan, attach the associated cable to the
connector for the temperature sensor or the fan on the system board.
Removing the processor


If the processor has a temperature sensor or a fan, pull out the associated cable.


Press the clamps (2) on either side of the processor slightly outwards (B) and pull the
processor up and out. Use a screwdriver if necessary.

Upgrading main memory

These slots are suitable for 64 to 512 Mbyte RDRAM memory modules of the RIMM format. The
permissible total size of the main memory is 1 Gbyte.
Memory modules with different memory capacities can be combined.
All locations must always be occupied. Missing memory modules must be replaced with
!
a C-RIMM module. This C-RIMM module must then be installed in the order of the
locations behind the RIMM memory module:
Location bank 0 = RIMM memory module
Location bank 1 = C-RIMM memory module
The system board supports a maximum of 32 RDRAM modules at all locations for the main memory
combined:
64Mbit technology
128Mbit technology
256Mbit technology
You may only use 2.5V RIMM memory modules.
!
The system board supports memory modules of the speed classes PC600, PC700 and
PC800. Always use memory modules of the same speed class. Otherwise the memory
speed is limited to the slowest speed class. Optimal system speed is achieved when you
use PC800 RDRAM memory modules.
