If you go to buy separate components must be cautious and know what type of memory you need your computer, and that it is the right size to not clash with any other component (such as CPU fan) when the install.
In the case of modern chipsets, accept high memory speeds, which can reach up to 1600 MHz.
So it is essential that we buy RAM that can be accepted by our motherboard. In the event that the memory you have more speed than the motherboard, what will happen in this case is that you will not draw out, since only operate at the maximum speed that allows our motherboard.
This is an important factor when buying more computer memory for our parameters. Latency indicates how fast the memory can access data that is stored. In conclusion this means, the less latency, the better.
