3.2 Main memory
The CPU boards offer room for two main memory modules. Dual-Channel memory technology
is supported when two modules of the same size (e.g. 1 GB) are plugged in. This technology is
not supported when two modules of different sizes (e.g. 1 GB and 2 GB) are plugged in.
When two 2 GB modules are plugged in, only 3 GB of main memory can be used.
