PCI-953 Single Board Computer User’s Guide

Main Memory
The PCI-953 single board computer provides two DDR-400, 184-pin DIMM sockets, which support
non-registered, ECC, and non-ECC DDR modules up to 1GB per socket, 2GB total. The maximum
memory size for 2.5V DDR-400 SDRAM is 1GB per socket, 2GB total unbuffered. Different size
DRAM modules may be used.
The PCI-953 single board computer will automatically detect the
memory clock, based on the processor and SDRAM used.
For system compatibility and stability, do not use generic DIMM. Use single- or double-sided
DDR-400 DIMM modules.

Installing Memory
Note:
For system stability, do not change any of the DRAM parameters in BIOS
setup to upgrade your system performance. See Chapter 4 for details.
CAUTION)
DIMM sockets are very durable but can be broken.
Use extreme care when removing a DIMM from a socket. Make sure
the DIMM is in the correct orientation before installation.
Any DIMM
sockets broken due to abuse, mishandling or accident are not
covered under the warranty.
CAUTION)
Be sure to take proper electrostatic precautions before starting any
work. See “Preventing Electrostatic Discharge” on page xiii.
Important: Although the MCH can run with single channel memory (with only one
module installed), it is recommended that the memory be populated in pairs to
gain the advantage of dual channels (Figure 1-1).
