Dual-Channel mode Population Rule
In Dual-Channel mode, the memory modules can transmit and receive data
with two data bus channels simultaneously. Enabling Dual-Channel mode can
enhance 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 backward compatible. Always install DDR3 memory modules
in DDR3 DIMM slots.
•
To ensure system stability, memory modules must be of the same type and
density in Dual-Channel mode.
•
Due to chipset resource usage, the system will only detect up to 15+ GB of
memory (not full 16 GB) when all DIMM slots have 8GB memory modules
installed.
