Dual-Channel mode Population Rule
In Dual-Channel mode, the memory modules can transmit and receive data with two
data bus lines simultaneously. Enabling Dual-Channel mode can enhance the system
performance. The following illustrations explain the population rules for Dual-Channel
mode.

Important
DDR3 memory modules are not interchangeable with DDR2 and the DDR3 standard
is not backwards compatible. You should always install DDR3 memory modules in
the DDR3 DIMM slots.
In Dual-Channel mode, make sure that you install memory modules of the same type
and density in different channel DIMM slots.
To enable successful system boot-up, always insert the memory modules into the
DIMM1 first.
Due to the chipset resource deployment, the system density will only be detected up
to 15+GB (not full 16GB) when each DIMM is installed with a 4GB memory module.
