1.9.1 CPU FSB and Memory Speed
The PCA-6008 can accept DDRII SDRAM memory chips without parity. Also note:
The PCA-6008 accepts DDRII 400MHz SDRAM and DDRII 533MHz SDRAM,
depending on the CPU front side bus frequency (FSB). Please refer to the table
below for the relationship between the CPU FSB and memory speed.
1.9.2 Dual Channel Configuration
The 2 DIMM sockets are arranged in two channels: DIMM1 in channel A and DIMM2
in channel B.
It is suggested to use a "Matched pair of DIMMs" which means: same in speed
(DDR266, DDR333, DDR400), same in size (128MB, 256MB, 512MB or 1GB), same
in chip density (128 Mb, 256Mb or 512Mb and same in CSA latency. Any other mem-
ory configuration will result in single channel memory operation.
1.10 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket are in the
"open" position. i.e. The handles lean outward. Slowly slide the DIMM module along
the plastic guides on both ends of the socket. Then press the DIMM module right
down into the socket, until you hear a click. At this point the two handles have auto-
matically locked the memory module into the correct position of the DIMM socket. To
remove the memory module, just push both handles outward, and the memory mod-
ule will be ejected by the mechanism in the socket.
1.11 Processor Installation
The CPU on the board must have a fan or heat sink attached, to prevent overheating.
1. The CPU has a plastic cap on it to protect the contact from damage. Before you
install the CPU, always cover it to protect the socket pin. First, remove the cap
from the lever hinge side and the pins of socket will be visible.
2. Open the load lever. Then, lift the load lever up and open the load plate.After
confirming the CPU direction for correct mating, gently push the CPU down in
the socket housing frame. Be sure to grasp on to the edge of the CPU base.
Note that the alignment keys are matched.
3. Place the load plate onto the package. Press the load lever down lightly onto
the load plate, and then secure the lever with the hook under retention tab. Con-
firm that your CPU cooler is firmly installed before turning on your system.

Warning! Without a fan or heat sink, the CPU will over-heat and cause damage to both the
CPU and the single board computer. To install a CPU, first turn off your system and
remove its cover. Locate the processor Socket 479
