Performance features
Performance Channel Mode
In this mode, the maximum performance and capacity can be achieved.
All three channels of a CPU must be populated identically as regards the
size and organization of the memory modules.
The slots within a channel do not have to be populated identically, but the
corresponding slots of all three channels of a CPU must be populated identi-
cally.
Memory modules with different clock frequencies and different speed ratings
can be used within a channel, whereby the settings of the slowest memory
module are used for this channel.
In this mode, symmetrical fitting of the slots of both CPUs is not required.

CAUTION!
If only one CPU is installed, the empty DIMM slots must be fitted with
dummy DIMM modules to ensure sufficient cooling of the system (this
does not apply if two CPUs are installed).
