NOTES:
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, you still run at 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, you run at 1066MHz.
If you install 3DPC in one channel (if applicable) and 1DPC in all other channels, you run at 800MHz.
95 Watt CPU's are required for 1333MHz DIMM speeds. All other CPU's are capable of up to 1066MHz.
References to the above MHz speeds are for the various speeds of DDR3 DIMMs; 1333 refers to DDR3-1333, etc.
