Installing or Replacing the Processor
Note: If you decide to install a processor on your own, observe the precautions in 'Before You
Begin'
As default, the CC8-BLUES comes fully equipped and tested with a processor. So normally there
should be no need to install a processor.
Due to the very compact construction of the CC8-BLUES, a ZIF socket for the processor could
not implemented. Instead, the CC8 features a high quality industrial PGA 370 socket with
precision contacts. You will need a special tool to remove the processor from this socket. If you
try to remove the CPU without the PGA extracting tool, the processors case or its contact pins
could be damaged. We suggest that you install or replace the processor only if you own an ESD
workstation and the matching extracting tool.
Before the processor can be replaced, you would have to remove the passive heatsink, which is
fitted by screws to the board and attached by conductive pads and/or adhesion to the
processor. Special handling is required to remove the heatsink and to re-install it afterwards,
including renewing the conductive adhesion and adjustment of the mounting screws.
Conclusion: Do not attempt to replace the processor by yourself, unless you are an absolute
professional. Instead, send in the board to EKF.
Installing or Replacing the Memory Module
Note: If you decide to replace the memory, observe the precautions in 'Before You Begin'
By default, the CC8-BLUES comes fully equipped and tested with a 64MB...256MB SD-RAM
memory module. So normally there should be no need to install a memory module.
Because the main memory is also used as video memory, the CC8-BLUES requires a PC-100
(100MHz) SDRAM SO-DIMM module even when the processor front side bus is 66MHz (Celeron
only). It is highly recommended that Serial Presence Detect (SPD) SO-DIMMs be used, since this
allows the chipset to accurately configure the memory settings for optimum performance. If
non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings,
but performance and reliability may be impacted.
A replacement memory module must match the 144-pin SO-DIMM form factor (known from
Notebook PCs), 3.3V, 100MHz unbuffered, non-ECC style. Be sure to buy no module with a
height >1.100 inch. Suitable modules are available up to 256MB. The 810GMCH supports
modules of up to a maximum of 12 address lines (A0...A11). However, there are also 256MB
memory modules on the market organized by 13 address lines, which are not suitable.
Conclusion: Replacement of a memory module is easy, but unnecessary in most cases.
