Optimizing RAM

Maximum speed and overclocking
The current Intel chipsets accept the Haswell generation memory speed up to 1600 MHz, some allow higher speeds advantage by overclocking RAM. In the case of Skylake generation DDR4 the base speed is 2133 MHz (better enough to play), and Z170 chipset can increase that speed. The H81 chipset supports up to 16GB of RAM, and other current Haswell chipsets accept up to 32GB, while the Skylake support up to 64 GB. You can consult our article on motherboards (motherboards or motherboard) to learn more about it.

If you buy more speed memory nothing happens, because it is compatible but will run at the speed at which you limit your motherboard. In case the processor, motherboard and memory are compatible with their best balance bike selection (Extreme Memoty Profile or memory profiling, the most common is that they are), you can make them work to the actual speed of the memory without having to resort to overclocking. Usually you have to activate it in the BIOS, and the AMD called AMP plates.

latency
A parameter to consider when buying memory latency. It is a parameter that indicates how fast it is able to access the data memory that stores and can be interesting to distinguish two memories same frequency. As a general rule, not going into great technical detail, is that the less the better latency.

The difference in memory performance against a 1333 MHz 1600 MHz is noticeable when playing, but from 1600 to 1866 is not so. But those who want to scrape some fps more of your graphics card is recommended that you always buy some the highest frequency that supports your plate. The difference between 1600 and 2133 MHz can be of 2 or 3 fps, while that from 1333 to 2133 can be up to 7 fps (1080p, medium quality).

The latency parameter you will see depicted as 9-9-9 or the like in the data sheets of the memory modules. They are the values of sub-timing or sub-beats. You have an excellent article (in English) on the website AnandTech about it if you want to know what exactly indicates each value. The lower, the better.

Keep in mind that increasing the memory frequency will increase the sub-beats, but access times measured in nanoseconds, will be lower, so do not worry if your memory 1600 has 9-9-9 and your memory 2133 It is 11-11-11. It is a parameter that can distinguish same frequency which is faster. Furthermore, in a lot of applications it affects the bandwidth available (that is based on the frequency) latency.
