[SOLVED] Single Channel vs Dual Channel RAM : Which one is Better?

If you are planning to upgrade your PC soon.The RAM is one of the most vital parts of the upgrade list.RAM pushes the system to achieve the best possible performance.A better and faster RAM ensures faster information transmission.Using a slower RAM will result in bottleneck the Processor performance.The CPU will work faster and will have to wait for the RAM to deliver the information.A single channel vs dual channel ram comparison will clear the things out properly.

The advancement in technology has tried to address this issue of speed barrier.The RAM has switched to dual and third channel memory module to increase the information transmission.The most popular being the Dual channel RAM among the power users.Today, we will be comparing the Single Channel vs Dual Channel RAM.Do the dual channel memory module RAM help in increasing the performance, or it is just hype? If, yes is it worth upgrading to Dual Channel RAM?

Single Channel vs Dual Channel RAM: Architecture

A ram operates on 64 bit of data channel, which means the RAM can push down in a single pipeline having 64 bits together in total bits.The Single Channel Architecture is shown below:

This is the conventional memory module with the single channel for transmission.Nowadays, the system supports multi channel platforms i.e. more than one communication channel.In the particular case of Dual Channel RAM, the memory module transmits the information at the double the rate as compared to single channel one.Now, we have got 2×64-bit channels available to the memory. This means we’ve increased the data traces running on the memory bus, and now have an effective 128-bit channel.

 

Single Channel vs Dual Channel RAM: How does the DDR3 1333 differ from 1600?

The 1333 and 1600 designations refer to the transfer rates – theoretically, given same CAS latency, DDR3-1600 would perform better than DDR3-1333 due to its greater maximum bandwidth.

However, in practice, very few applications are bound by memory access, and the performance differences are within the margin of statistical error from one another unless you’re trying to game on an integrated GPU – and even then, not so significant as to invest worthwhile.

Single Channel vs Dual Channel RAM: Benefits of Dual Channel RAM

  1. Dual channel allows for wider (64 vs 128 bit) memory data bus. In theory, this should enable the system to move data faster since it can use a single call rather than two. In practice, there is only a minor gain in most mainstream workloads.
  2. Additional DIMM slots mean you can physically install more RAM. Larger RAM modules get more expensive or just do not exist. (Try getting a 16GB DDR3 non-ECC module.) These additional slots allow you to install more RAM. Getting 4x4GB is cheaper than 2x8GB.

Single Channel vs Dual Channel RAM: Conclusion

Dual channel RAM is simply faster than single channel RAM.
In short, Single Channel RAM operates on a single 64-bit data channel.  Meaning it has 64bits to use at one time.  Dual Channel RAM can operate up two 64-bit data channels, doubling its POTENTIAL speed. Now the channels are not separate or independent, so please keep that in mind.

Dual Channel likely will not show any huge difference in gaming or things of that nature, BUT for rendering, compiling, and encoding there’s a dramatic advantage.

But generally speaking, there will be advantages to using dual channel RAM over a single channel.  Even if you’re going to want to use dual-channel.  Besides, performing even 10% better is still “better”.
