Dual-Channel Mode Population Rule
In Dual-Channel mode, the memory modules can transmit and receive data with two
data bus lines simultaneously. Dual-Channel mode is enabled when the installed
memory capacities of both DIMM channels are equal. If different speed DIMMs are
used between channels, the slowest memory timing will be used.
Dual-Channel mode can be achieved with two, three or four DIMMs. To achieve Dual-
Channel mode, the following conditions must be met:
* Matched DIMM configuration in each channel
* Same Density (512MB, 1GB, 2GB, etc.)
* Matched in both Channel A and Channel B memory channels
* Populate symmetrical memory slots
Configurations that do not match the above conditions will revert to Single-Channel
mode.
