If you want to use three DIMMs in a dual-channel configuration, install a matched pair
of DIMMs equal in speed and size in the DIMM 0 (blue) socket of channel A and the
DIMM 0 (blue) socket of channel B. Install the third DIMM in the DIMM 1 (black)
socket of either channel A or channel B (see Figure 16).
