For best performance, DIMMs should be populated using the following guidelines:
Each installed processor should have matching DIMM configurations
The following DIMM population guidelines should be followed for each installed processor
o
1 DIMM to 3 DIMM Configurations
– DIMMs should be populated to DIMM Slot 1 (
Blue Slot
) of
Channels
A
thru
C
o
4 DIMM Configurations
– DIMMs should be populated to DIMM Slot 1 (
Blue Slot)
of Channels
A,
B, D,
and
E
o
5 DIMM Configurations
–
NOT Recommended
. This is an unbalanced configuration which will
yield less than optimal performance
o
6 DIMM Configurations
– DIMMs should be populated to DIMM Slot1 (
Blue Slot
) of all Channels
o
7 DIMM Configurations
–
NOT Recommended
. This is an unbalanced configuration which will
yield less than optimal performance
o
8 DIMM Configurations
– DIMMs should be populated to DIMM Slots 1 and 2 of Channels
A, B, D,
and
E
o
9 DIMM, 10, DIMM,
and
11 DIMM Configurations
-
NOT Recommended
. These are an
unbalanced configurations which will yield less than optimal performance
o
12 DIMM Configurations
– DIMMs are populated to ALL DIMM Slots
Note: DIMM populations noted as “Not Recommended” are fully functional configurations. However, they
will not yield the best possible system performance.

DDR4 DIMM Installation

1.
Locate the DIMM sockets. Make sure the clips at either end of the DIMM socket(s) are pushed outward to
the open position (see Letter “A”).
2.
Holding the DIMM by the edges, remove it from its anti-static package. Position the DIMM above the
socket. Align the notch on the bottom edge of the DIMM with the key in the DIMM socket (see Letter “B”).
3.
Insert the bottom edge of the DIMM into the socket (see Letter “C”).
4.
When the DIMM is inserted, push down on the top edge of the DIMM until the retaining clips snap into
place (see Letter “D”).
5.
Make sure the clips are firmly in place (see Letter “E”).
