2.2 CPU Installation:
The SYS7180VE Industrial CPU Card supports a single Intel
®
P4 Celeron
TM
or
Celeron D
TM
processor and Pentium 4
TM
processor. 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
card through the 478-pins socket.
The CPU card supports the processors listed in table below:
P4 Celeron
TM
processor
Host Bus frequency Cache size
400MHz 128KB
Pentium 4
TM
processor
Host Bus frequency Cache size
400MHz / 533MHz 512KB
Celeron D
TM
processor
Host Bus frequency Cache size
533MHz 256KB or 1M
The socket-478 comes with a lever 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.
Note: 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.

2.3 Main Memory Installation: DIMM1/2
The SYS7180VE Industrial CPU Card supports two single-side or double-sided
DDR266/333 unregistered, DIMM 184-pin sockets for a maximum total memory of 1GB.
Using the non-ECC DDR SDRAM DIMMS.
The CPU card supports the following memory features:
• 184-pin DIMMs with gold-plated contacts
• 266MHz and 333MHz non-ECC DDR SDRAM
• Un-buffered single or double-sided DIMMs in the following sizes:
SDRAM
SYNCHRONOUS DRAM (SDRAM) improves memory performance through
memory access that is synchronous with the memory clock. Burst transfer rates at x-1-1-1
timing can be achieved using SDRAM, while asynchronous memory subsystems are
typically limited at x-2-2-2 transfer rates.
The CPU card supports single or double-sided DIMMs in the following sizes:
DIMM size Non-ECC configuration
16MB 2Mbit x 64
32MB 4Mbit x 64
64MB 8Mbit x 64
128MB 16Mbit x 64
256MB 32Mbit x 64
Note: All memory components and DIMMs used with the SYS7180VE CPU card 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.
