Memory Population Rule

Please refer to the following illustrations for memory population rules. 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 ensure a 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.
