Branch Channel Geometry:
Each bit specifies the X4 or X8 geometry of a single or double-density DIMM. This configures the
DMH to respond to the appropriate DIMM data strobes and drive dual-use DQM pins appropriately.
Setting a bit to 0 indicates X4 geometry, while setting a bit to one specifies X8 geometry.
