Owners Manual

The system contains 12 memory sockets split into four sets — two sets of 4 sockets and two sets of 2 sockets each. Each
4-socket set is organized into two channels and each 2–socket set is organized into one channel. In each channel of the
4-socket set, the release levers of the first socket are marked white and the second socket black. In the 2-socket set, each
release lever is marked white.
NOTE: DIMMs in sockets A1 to A8 are assigned to processor 1 and DIMMs in sockets B1 to B4 are assigned to processor 2.
