NOTES:
PC3-10600 DIMMs have a maximum speed of 1333MHz. PC3-8500 DIMMs have a maximum speed of 1066MHz
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 1066MHz DIMM in channel 1 and 1x 1333MHz DIMM in channel 2, the maximum speed will be 1066MHz.
If you install 1x 1066MHz DIMM in channel 1 and 5x 1333MHz DIMMs with 1 DIMM Per Channel (DPC) in each of the other channels,
the maximum speed will be 1066MHz.
If you install 3DPC in one channel (if applicable) and 1DPC in all other channels, you run at 800MHz.
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.
