The system contains 12 memory sockets split into two sets of six sockets, one set per processor. Each six-socket set is
organized into three channels. In each channel, the release levers of the first socket is marked white and the second
black.
NOTE: DIMMs in sockets A1 to A6 are assigned to processor 1 and DIMMs in sockets B1 to B6 are assigned to
processor 2.
