A quick reference for the recommended DIMM population order is shown in
Table 25
and
Table 26
. CPU 1
DIMM population order is shown as an example. Pick the number of DIMMs in the table you wish to populate,
then, starting with A0, populate down Bank 0, then down Bank 1, then down Bank 2 until you reach the
number you picked. If you picked 8 DIMMs, for example, use
Table 25
and populate DIMMs in A0, B0, C0,
D0, A1, B1, C1, and D1. If you picked 6 DIMMs, for example, use
Table 26
and populate DIMMs in A0, B0, C0,
A1, B1, and C1, leaving D0 and D1 empty.
