NOTES:
PC3 14900 DIMMs have a maximum speed of 1866MHz.
Mixing DIMM speeds is allowed, but the system processor speed rules always override the DIMM capabilities
If you do mix DIMM speeds, the memory bus will default to the minimum clock rate of all DIMMs in the system - even if the slower
DIMM is on the other processor
If you install 1x 1600MHz DIMM in channel 1 and 1x 1866MHz DIMM in channel 2, the maximum speed will be 1600MHz If you
install 1x 10661600MHz DIMM in channel 1 and 5x 1866MHz DIMMs with 1 DIMM Per Channel (DPC) in each of the other channels,
the maximum speed will be 1600MHz
If you install 2DPC in one channel (if applicable) and 1DPC in all other channels, you run at 1866MHz
Maximum memory speed will also depend on the processor installed
References to the above MHz speeds are for the various speeds of DDR3 DIMMs; 1333 refers to DDR3-1333, etc.
