Populating DIMMs in Dual-Processor Systems for Optimal
System Performance
In dual-processor systems, populate DIMMs into DIMM sockets starting with processor 0 (P0)
D0, then, alternating between sockets associated with processor 0 (P0) and matching sockets
for processor 1 (P1). Fill the black sockets first, then the black sockets with white tabs, and
then the white sockets, as shown in the following figure. Notice that the order of populating the
black DIMM sockets is Ch C first, Ch A second, Ch D third, and Ch B last. Repeat the same
population sequence for the black sockets with white tabs, and finally, for the white sockets.
