How to choose a memory RAM - this is a very important part of the computer which, along with the central processor determines its speed.If you think that your computer does not have enough memory, you can put it another bar of RAM. How to choose a memory?

To select the memory, you need to learn, what type of memory supported by your motherboard .There are three main types of memory: DDR, DDR2 and DDR3.DDR memory was used in old computers, is now to find a computer with DDR memory is not easy.The most common type - DDR2, and on the newest machines is memory DDR3.Check the type of memory can be in the manual to your motherboard.

also important to choose a memory with a clock frequency suitable .Frequency is measured in megahertz, depending on the type of memory, but in the framework of one type there are different clock speed.For example, DDR2 memory could have a frequency of 667 to 1066 MHz, DDR3 - from 800 to 1600 MHz.

memory clock speed affects the performance of your computer.That is, two strips the same size will be t

he one with the higher clock speed .Usually the best choice for DDR2 - 800 MHz for DDR3 - 1333MHz.

But note that if you want to choose a memory in addition to the already established, its clock frequency should be the same .The fact that the computer selects for lower clock frequency of two modules, so the installation module at a frequency lower speed of the entire system, and the installation of the module with greater - nothing.Volume modules is not necessarily be identical.

Speaking of volume.Most popular memory modules have a capacity of 1024 or 2048 MB (1 GB or 2, respectively). optimum amount depends on what you use your computer .Internet and office applications may be sufficient 1GB for games and graphics need at least 2 GB.However, keep in mind that when the feeble processor, more memory will not help.

If the total amount of RAM installed on your computer is more than 3 GB, you will need to install a 64-bit operating system .The fact that 32-bit systems "see" no more than 3.25 GB of RAM and 64-bit can support up to 192 GB of RAM (depending on the version of the operating system).

Even at the speed of RAM affects the so-called timing (latency) memory .It refers to delay time which is required to execute a particular command.Without going into details, let us say simply that the smaller the timing - so much the better of the two strips with equal frequency faster than the one with the smaller timing.

To select the memory, it is necessary to understand the labeling. Usually marking the type and frequency of memory , for example, DDR2-800.There is another option of marking.Memory type denoted PC (PC, PC2, PC3).Thus, the type corresponds to the type DDR2-800 PC2-6400.To read clock frequency, it is necessary to divide the number of the marking 8 and rounded, if necessary.

If you buy more RAM in addition to the bar, which you already have (ie, plan to use a dual-channel mode ), it is important that they not only have the same clock speed, but also the possibility of one manufacturer were sometimesit is that the straps from various manufacturers refuse to work in tandem.

When choosing should also pay attention to the manufacturer.It is best to choose a memory from the manufacturer, proven in the market - Kingston, Corsair, Apacer, OCZ, PQI, GelL, Patriot, Hynix and other .At the hearing as a well-known manufacturer like Samsung, but it basically does not produce strips and chips, which are then used by other manufacturers.

Select memory is not as difficult as it may seem, but it does not mean that in choosing memory strip must be approached carelessly: if you want your computer to "fly", it is necessary to consider all the possible characteristics of RAM .
