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 31+ GB of memory
(not full 32 GB) when all DIMM slots have 8GB memory modules installed.
