NOTES:
 DIMM#2 & #3 shared same memory bus and DIMM#1 is dedicated for 2
nd
channel memory bus.
We recommend you to use the same color DIMM socket to obtain the best
memory performance.
For one DIMM memory configuration, the DIMM can be located on either of
DIMM#1 to DIMM#3 in 64-bit mode
In two DIMMs memory configuration, the DIMMs can be located on
DIMM#2/#3 and DIMM#1 in 128-bit mode. And keeping these DIMMs in
same type and same size are preferred.
In three DIMMs memory configuration, the DIMMs can be located on all
DIMM sockets in 128-bit mode.
 Using non-compliant memory with higher bus speeds (overclocking) may
severely compromise the integrity of the system.
