When installing DIMMs, you must follow the following population rules to deliver the best
performance:
Maximize number of channels populated first
Balanced DIMM population across channels and sockets.

With two processors installed, the system will operate only if the DIMM slots of one
processor are populated. In this case, memory is shared between the two processors.
However, due to the associated latency of this configuration, this is NOT a recommended
operating mode.
You can find additional technical information for the memory sub-system in the Technical
Product Specification (TPS).
2.3.3 Installing a DIMM
CAUTION
Before adding or removing DIMMs or other system components, you
must unplug the power supply. Failure to do so may cause severe
damage to both the server board and the components.
1. Unlock a DIMM socket by pressing the retaining clips outward.
2. Align a DIMM on the socket so the notch on the DIMM matches the break on the
socket.
