HP ProLiant ML150

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
References to the above MHz speeds are for the various speeds of DDR3 DIMMs; 1333 refers to DDR3-1333, etc.
