Dual-Channel Memory Architecture

Memory Modules and Sockets

This MSI MS-7053 motherboard supports dual-channel memory architecture and has colour coded memory sockets. Dual-channel architecture doubles the data bandwidth and is better than single-channel architecture. All motherboard manufacturers have their own colour-coding scheme and it is always best to consult the official manual to find out how to install the memory.

When you place one memory module on each channel, the processor makes use of both channels and both memory modules simultaneously thereby effectively increasing the data bandwidth. The full performance of a dual-channel system is usually realised when a processor has hyper-threading or multi-pipeline features, and in addition, the software has the code features to make use of it.

This motherboard has four sockets and can therefore accept four sticks of memory. Each slot can have a maximum of 1 GB. The green sockets marked DIMM1 and DIMM2 are the Channel A pair. The orange sockets marked DIMM3 and DIMM4 are the Channel B pair.

For the best performance, you need at least one memory module on each channel, and on this build, I have 1 GB module on socket marked DIMM1, and 1 GB memory module on socket marked DIMM3. These memory modules are the fastest the motherboard allows and I made sure they were a matching pair.

Whether your system runs in dual-channel mode, or single-channel mode, depends upon what you have plugged into the sockets. Generally, a matched pair of memory modules, one on each channel is usually good enough. A matched pair is memory of the same size and speed, and many professionals even go to extreme lengths to make sure it is from the same manufacturer and batch number.

Depending upon the motherboard, unmatched memory may not work and your system may default back to single-channel-mode. If for example you had 512 MB in Channel A, and 1 GB in Channel B then the controller may default to single-channel mode. If you had two DIMM modules in one channel and only one module in another, then again, the system may default to single-channel mode.
