3.2 Memory Module Installation
The cPCI-6841 Series SBC provides two 200-pin SODIMM sock-
ets for DDR-SDRAM with a maximum memory capacity of 2GB. If
memory modules are pre-installed when the package is received,
this section may be skipped.
The GMCH system memory controller directly supports the follow-
ing:
X One channel of DDR SDRAM memory
X DDR SDRAM devices with densities of 128-Mb, 256-Mb,
and 512-Mb technology
X Up to 2GB (512-Mb technology) using high density devices
with two DIMMs
To install the memory modules, align the notch in the memory
module with the key on the DIMM slot and follow the procedure
shown in Figure 3-3 below. When installing memory, ensure that
each DIMM module is firmly seated in its socket and does not
interfere with any components.
