DIMM Slot Numbering and Color Coding
Each CMOD contains 12 DIMM slots arranged in two groups of six slots. Each group of slots
is controlled by one of the four memory buffers. Each buffer has two independent memory
channels, Ch A and Ch B (six memory channels per CMOD). Each channel supports 1-6
DIMMs and has six assigned DIMM slots.
Channels 0, 1, and 2 are located on one side of the processor, and channels 3, 4 and 5 are on the
other side of the processor. To differentiate the two memory channels within a group of slots,
and to assist in DIMM population order, the six DIMM slots assigned to each channel have
color-coded black slots with black levers, or white slots with white levers.
