You can add DIMMs according to the following rules:
You cannot add DIMMs to a 32–DIMM system because it is already fully populated.
All DIMMs must have their parameters matched, as described above.
Only four or eight DIMM upgrades are supported. As a result, all color blocks must be either full or empty.
DIMMs must be populated in the correct order.
On a 16–DIMM CMOD, all the blue and white slots should already be populated.
When you add DIMMs, fill the black slots (D1/D5 and D10/14) first, and fill the green slots (D3/D7 and D11/D15) last

The following figure shows the location of the DIMMs on the CMOD.
