Dual-Channel mode Populaton Rule
In Dual-Channel mode, the memory modules can transmt and receve data wth two
data bus lnes smultaneously. Enablng Dual-Channel mode can enhance the system
performance. The followng llustratons explan the populaton rules for Dual-Channel
mode.

Important
DDR3 memory modules are not nterchangeable wth DDR2 and the DDR3 standard
s not backwards compatble. You should always nstall DDR3 memory modules n
the DDR3 DIMM slots.
In Dual-Channel mode, make sure that you nstall memory modules of the
same type
and densty n derent channel DIMM slots.
To enable successful system boot-up, always nsert the memory modules nto the
DIMM1 rst.
Due to the chpset resource deployment, the system densty wll only be detected up
to 31+GB (not full 32GB) when each DIMM s nstalled wth a 8GB memory module.
