SCP-8550-LLV
CPU Installation:
This board supports a single Intel Celeron M or Pentium M processor (FSB 400MHz). The processor’s
VID pins automatically program the voltage regulator on the CPU card to the required processor voltage.
The host bus speed is automatically selected. The processor connects to the CPU board through the 478-
pins socket.
The socket-478 comes with turn lock to secure the processor. Make sure the notch on the corner of the
CPU corresponds with the notch on the inside of the socket.
After you have installed the processor into the socket 478, check if the configuration setup for the CPU
type and speed are correct. The CPU should always have a Heat Sink and a cooling fan attached to
prevent overheating.
Refer to the description of optional heat sink fan appending for attachment of a heat sink fan.
CAUTION
Ensure that the CPU heat sink and the CPU top surface are in total contact to avoid CPU overheating
problem that would cause your system to hang or be unstable.
Main Memory Installation: DIMM1/DIMM2
The SCP-8550-LLV CompactPCI Industrial CPU board supports two dual inline memory module (DDR
SDRAM DIMM 184-pin) sockets for a maximum total memory of 2GB. Using the serial presence detect
(SPD) data structure, programmed into an E
2
PROM on the module, the BIOS can determine the size of
SDRAM and speed. Minimum memory size is 256MB; maximum memory size is 1GB. Memory size
and speed can vary between sockets.
The CPU board supports the following memory features:
-
2.5V specification 184-pin DDR SDRAM DIMM with gold-plated contacts
-
266MHz (PC2100)/ 333MHz (PC2700) DDR SDRAM.
-
ECC function support.
-
Single or double-sided unbuffered DIMM.
Supports single or double-sided DIMMs in the following sizes:
DIMM size
Non-ECC configuration
128MB
16Mbit x 64
256MB
32Mbit x 64
512MB
64Mbit x 64
1GB
128Mbit x 64
CAUTION
All memory components and DIMMs must comply with the PC SDRAM Specification. These
include: the PC SDRAM Specification *memory component specific), the PC Unbuffered DIMM
Specification, and the PC Serial Presence Detect Specification.
