NOTES:
•
PC3-10600 DIMMs have a maximum speed of 1333MHz. PC3-8500 DIMMs have a maximum speed of 1066MH
•
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 i
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
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.
