Memory Configurations

The Intel Core i7 and Intel Xeon Processors support the following types of memory
organization:
• Tri/Dual channel (Interleaved) mode. This mode offers the highest
throughput for real world applications. Interleaving reduces overall memory
latency by accessing the DIMM memory sequentially. Data is spread amongst the
memory modules in an alternating pattern.
⎯ Three independent memory channels give two possible modes of interleaving:
• Tri-channel mode is enabled when identical matched memory modules are
installed in each of the three memory channels (blue connectors).
• Dual channel mode is enabled when two of the blue memory connectors are
populated with matched DIMMs.
• 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 installed memory modules are not matched.
Technology and device width can vary from one channel to the other.
