ADLINK cPCI-3965 - Manual (Page 50)

36 Getting Started
5.2 Memory Module Installation
The cPCI-3965 Series supports DDR2-667 unbuffered non-ECC
memory modules via two stacked-type SO-DIMM sockets. The
SO-DIMM modules have a 200-pin footprint and are notched to
facilitate correct installation in the SO-DIMM sockets. At lease one
memory module will be pre-installed in the lower socket as shown
below.
NOTE: NOTE:
The front panel and the layer 2 PCB (DB-3965L2) should be
removed before installing memory modules to the cPCI-3965D
dual slot version.
