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.
●
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.

CAUTION!
If only CPU 1 is installed, the empty DIMM slots of CPU 1 must be fitted
with dummy DIMM modules to ensure sufficient cooling of the system
(this does not apply if two CPUs are installed).
