Building your own computer is no easy task. There is no much to be done and lots of aspects that have to be considered so that your computer is up and running. One of the important aspects that needs to be considered is the PC RAM memory without which it is impossible for the computer to run. It may be mentioned that a lot of the data on yoru PC lies in the hard dick drive. It is the RAM or the Random Access Memory that helps in accessing, retrieving and then using the data as and when required so that the output may be easily obtained. So even though you have enough and god hardware and software, without RAM it may be tough to ensure that your PC runs properly and it may conk off every now and then.

When you are building your own computer, it makes sense for you to look out as to how much of RAM would be needed. This is based on your computer usage and if you are using it for high level computing like gaming, you would need to make sure that the RAM is also adequate to take care of all these needs adequately. After all, if you are in the midst of important operations, you cannot afford to have to shut up on you in the interim. The main utility of the RAM is to quickly retrieve data on the RAM so that it can be effectively used in a jiffy. When you are using a large number of applications, this becomes a problem sometimes because this retrieval of data becomes slow and rather unwieldy leading to a general slowdown in the computer if not a complete shut down. This is where you need to ensure that your PC RAM memory is adequate for your needs and propensity for multi-tasking. You have to consider these facts so actively when you are looking at building your PC the right way.

When looking at enhancing the PC RAM memory, you need to know that RAM can come in various sizes ranging all the way up from 245 MB to almost 8 GB, where 8 GB RAM is essential for people who do gaming as well as high end animation work.
RAM is measured in megabytes or gigabytes. You can buy RAM memory modules in various storage capacities, including 256MB, 512MB, 1GB and 2GB. Your motherboard dictates the number of memory modules that you can use. Motherboards usually have only two slots for memory sticks. Modern motherboards can allow you to use more than two RAM modules.
If you intend to use Windows Vista as your operating system, try to get at least 2GB of RAM. Vista is a demanding program that will need a robust system.
Your motherboard also determines the type of RAM that you can use. There are three types of RAM memory used in computers today: DDR, DDR2 and DDR3. DDR3 is a relatively new technology so only the latest motherboards can support it.
So when building a computer, always get as much RAM as you can get your hands on! More RAM will not only permit you to run several programs together, it will also significantly increase the speed of your home built computer.
