Memory Configurations

The Intel Core i7 and Intel Xeon processors support the following types of memory organization:

•Quad-channel (Interleaved) mode. Quad-channel mode offers the highest throughput for real world applications.

•Tri-channel (Interleaved) mode. Tri-channel mode is enabled when the installed memory capacities of any three DIMM channels are equal.

•Dual-channel (Interleaved) mode. Dual-channel mode is enabled when the installed memory capacities of both DIMM channels are equal. Technology and device width can vary from one channel to the other but the installed memory capacity for each channel must be equal. If different speed DIMMs are used between channels, the slowest memory timing will be used.

•Single-channel (Asymmetric) mode. This mode is equivalent to single-channel bandwidth operation for real world applications. This mode is used when only a single DIMM is installed or the channel memory capacities are unequal. Technology and device width can vary from one channel to the other. If different speed DIMMs are used between channels, the slowest memory timing will be used.
