DIMM Slot Population Order

The DIMM slot population order is as follows:

Note:

Always populate the DIMM slot furthest from the memory buffer first.

  1. Installation Order DIMM: 1 D7, 2 D4, 3 D9, 4 D2, 5 D11, 6 D0, 7 D6, 8 D5, 9 D8, 10 D3, 11 D10, 12 D1

  2. Populate the slots with black slots and black levers: D0 D3 D6 D9 D12 D15 D18 D21

    The slot population for the minimum DIMM configuration is D0/D6/D12/D18 per CMOD

  3. Populate the white slot, white lever slots: D2 D5 D8 D11 D14 D17 D20 D23

The following table describes the proper order in which to populate DIMMs in a CMOD using the numbered callouts in the above figure, and the DIMM socket labels (D0 through D11).
