Memory expansion
Main memory resides on two carrier boards called memory modules. The
memory modules are located under the control panel on the front of the server
and are connected with the main processor carrier board via a connection
modules.

Each memory modules contains slots for 16 DIMMs. The memory controller
supports PC 100-registered SDRAM DIMMs. Three DIMM sizes are supported:
256 MB, 512 MB and 1 GB. Memory sizes from 256 MB to 16 GB per module
are supported.

If only one memory module is installed, DIMM sizes on that module may
vary, but if both memory modules are installed, the DIMM configuration
on the two modules should be identical to support memory interleaving
for performance gains.
