NOTES:

• DIMM#2 & #3 shared same memory bus and DIMM#1 is dedicated for 2

nd

channel memory bus.
We recommend you to use DIMM socket of the same color to obtain the best
memory performance.
- For one DIMM memory configuration, the DIMM can be located on any of

DIMM#1 to DIMM#3 in 64-bit mode

- For two DIMMs memory configuration, the DIMMs should be located on

DIMM#2/#3 and DIMM#1 in 128-bit mode. It is preferable to use DRAM
DIMM of the same type and size.

- For 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.
