• Four DIMM sockets. Each socket hosts SDRAM 100 MHz non-ECC
memory modules that are used in pairs. The first two DIMM sockets
A0-B0, closest to the system board, contain the first pair of memory
modules. Upgrades are then installed in DIMM sockets A1-B1.

If any of the sockets are unused, leave them free, because a continuity
module is not required. When upgrading the memory, always use the
same type of SDRAM modules in pairs.
