Many users know what RAM is and what it is for. Almost all modern devices and gadgets are endowed with RAM (random access memory). So what gives such memory to a computer or laptop? Let's try to understand the issue.
What is it?
The RAM of a laptop or PC is an important part of the device system, on which the speed of various applications depends. Why do I need RAM in my computer? It stores the commands and temporary data that the computer processor needs to perform certain operations. There are many types of RAM, each of which performs its own task. The "RAM" looks like an elongated green chip. In the system unit or under the back cover of the laptop there is a compartment where it is located. Even a user who does not understand the technology will be able to install it himself.

What does RAM provide ? RAM or Random Access Memory (RAM) is a volatile and relatively fast PC memory that has random access. It carries out various kinds of operations for the exchange of information between devices. RAM is volatile. If you turn off the power, the data contained in it will be erased. RAM stores the streams of information that the processor needs to process. Devices are contacted with RAM via the system bus and exchanged with it via the cache. Random access RAM means that the memory, if necessary, refers directly to the desired block.
At the same time, the access speed does not change. RAM is different from volatile, it rarely crashes. If it is damaged, then this affects the entire system, negatively affects the operation of some PC devices. RAM comes as a separate module or unit of a device or chip. If modern element gadgets did not use the element in question, then all operations would occur slowly. What does adding RAM do? It allows you to reduce the time of information processing, and applications will run and run twice as fast.
Type and volume
What does RAM provide? It helps the computer run faster. To increase the capabilities of the device, it is necessary to know and take into account the characteristics of this element. For example, if the RAM is 8 GB, this is its size. It is an integral element of any module in the system. The performance of a computer or laptop depends on the total amount of RAM; the more it is installed, the better for the user.
How to correctly determine how much memory is installed on a PC? There are many ways to do this. If the computer is running Windows 7, then you need to do the following: click "Start", then right-click on "Computer" - "Properties". A window will appear that will contain information about the volume. There you can see information about the processor, the type of system. In the same way, you should find out the amount of RAM (8 GB, 16 GB, 32 GB, etc.) in Windows XP.
If the user needs to find out information about the module and other characteristics, it is necessary to install a special program to determine the parameters of the PC. Specialists are also advised to use S & M - a diagnostic application about the status of the computer.
Features
Modern laptop and computer users know what RAM provides. She is responsible for speed - how the incoming command will be quickly executed and processed by the PC. To determine the frequency of a particular module, you can simply look at the sticker where numbers and letters are indicated, for example: DDR3 - 1600 PC3 - 12800 CL9 ECC REG.
In addition, you can use special programs that allow you to determine the characteristics of RAM. What does this cipher mean?
- DDR3 is the generation of RAM, the most common type.
- 1600 - the operating frequency of the memory, which is measured in MHz.
- PC3 - 12800 - a parameter indicating bandwidth, that is, the amount of information processed in 1 second.
- C19 - Timing information in RAM, measured in milliseconds. The lower the score, the better.
- ECC - memory is endowed with parity. The module has a special controller that corrects errors that occur during operation.
Therefore, if you want to increase the RAM, then consider these parameters, otherwise the risk of incompatibility between the device and RAM is great.
RAM for laptop
Many modern netbooks, laptops and tablets use the DDR RAM type with the SODIMM form factor. The difference between these modules from others is their appearance. Each generation of RAM has its own characteristics. They are associated with the process. So, the laptop module has a different number of contacts, unlike the first generation DDR. Some laptop users may encounter an unpleasant problem: the OS "slows down", it works intermittently. This happens if multiple applications load at the same time. Then you need to clean up the RAM.
What can a user do? Close all applications, reboot the device. In addition, you can use programs that clean up RAM. All of these methods have pros and cons. If they do not solve the problem, you should contact a service center for help.
How to install?
We found out what RAM gives, now we will talk about how to install it in a computer or laptop:
- First, turn off the device, wait five minutes.
- Open the system unit.
- There should be free slots on the motherboard - install RAM there. Each board has its own DDR generation.
What gives an increase in RAM? The computer will work faster, but you need to increase it deliberately. First, find out which motherboard is installed on your device, also focus on the model and brand of the laptop. All this will make it clear how much RAM to add and whether to do it. To increase memory, do the following:
- determine the model of the motherboard or laptop;
- determine the amount of RAM and the module;
- check compatibility with the motherboard;
- purchase a module.
Installing memory is easy. To do this, you need to know in general terms what a PC or laptop consists of, the functionality of all its parts.
