Main memory

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).
3.2.1
Memory speed
The maximum DDR3 memory speed depends on the memory configuration on
one memory channel and on the CPU speed.
One DIMM per channel = max. 1333 MHz, two DIMMs per channel = max.
1333 MHz for 1.5 V memory / max. 1066 MHz for 1.35 V memory. The memory
channel with the lowest speed defines the speed of all CPU channels in the
system.
