SUPPLEMENTAL MATERIAL
A quick reference for the recommended DIMM population order is shown in
and
. 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 A1, populate down Bank 1, then down Bank 2, then down Bank 3 until you reach the
number you picked. If you picked 8 DIMMs, for example, use
and populate DIMMs in A1, B1, C1,
D1, A2, B2, C2, and D2. If you picked 6 DIMMs, for example, use
and populate DIMMs in A1, B1, C1,
A2, B2, and C2, leaving D1 and D2 empty.
