Archiving uses a lot of system memory. That is why the results obtained in WinRAR illustrate everything we have just said in a great way.
However, there are applications, which do not depend on the memory sub-system performance in overclocked systems. One example like that is Adobe Photoshop. Although, to be completely fair I have to say that in this case we still do see a slight difference in the performance of our test script applying typical actions to a 12-megapixel image.
We can say the same thing about x264 decoding speed: even in an overclocked system its performance barely depends on the memory frequency and timings settings.
However, during video transcoding in Cyberlink MediaShow things turn totally different. We obtained about 4% performance improvement from raising the memory frequency only one step up, and another 1.5-2% - from adjusting the timings by one cycle.
As for the effect from the memory sub-system settings on the performance in Autodesk 3ds max, we could say that it was average. In practice it means that if you are putting together a system mostly for final rendering work, then it makes more sense to focus on the CPU speed first and only then on high-speed memory.
And now comes the most interesting part. Memory frequency and timings in an overclocked gaming system have the same influence on the overall performance as in a system working in its nominal mode. And it means that even though we can clearly see the connection between the memory sub-system settings and fps rate on the diagrams, it will be barely noticeable during actual gameplay.
So, it turns out that overclocking doesn’t really change the dependence between the memory settings and system performance. As a result, during overclocking the potential of almost any DDR3 memory should be sufficient for building a well-balanced system. In other words, with a few specific exceptions in individual circumstances, overclockers shouldn’t really waste their time searching for high-speed memory. Especially, since LGA1156 processors have low minimal multiplier for the memory frequency, which allows using widely spread DDR3-1333 SDRAM even at a seriously increased base clock without any problems.
