How to find out how much RAM is on a laptop?

The amount of RAM, to a greater extent, affects the speed of the computer. Today we will tell how to determine how much RAM is already installed in the laptop, how to choose it correctly.

On what affects the amount of RAM

It was said that the amount of RAM determines how fast your device will work. With a lack of memory to complete the task, his work will slow down, he begins to "hang and slow down." This is a consequence of the fact that the machine tries to compensate for its lack of it by using permanent memory (ROM) or a drive.

Important! We warn - the lack of RAM, of course, slows down the speed of the device, but not only is it to blame - options are possible. Read the article, then decide.

How to know the characteristics of RAM in a laptop

Consider ways to determine the characteristics of RAM.

• Visual: Contact the device properties. Click on "My Computer" - select "Properties". We are looking for the desired line, we look at the RAM capacity. Use the "hot key combination" - type Win + R. In the line that opens, type dxdiag. Find the tab "System". We look at the physical characteristics of memory.

However, the information is limited to one line. If you want to know all the characteristics, then open the back cover of the device, get the bar, look directly at it. Here all important information is displayed. To make clear the designations, consider an example:

The bar was designed by Hynix, it has a capacity of 4 GB, by the abbreviation 1Rx8 we learn that it has one-sided mounting of elements (two-sided will have 2R), memory chips -8.

The bandwidth (PC3-12800) corresponds to DDR3 RAM with a maximum speed of 12,800 MB / s. Calculate the frequency of the OP: the maximum speed of 12,800 MB / s is divided by 8. We get the frequency equal to 1 600 MHz.

• Program: If you disassemble the new device does not allow superstition or manufacturer's warranty, you can determine the parameters of RAM by using software, for example, the AIDA64 program.

With it, you can find out all the parameters of the device:

1. Download, install the program.
2. Run the application. In the pop-up window (warning about trial, 30-day version) click "OK". Here is a program window divided into two parts. In one - the components of the PC, in their second characteristics.
3. Open the "Motherboard" - tab SPD. Here is the complete information about the installed RAM.

What volume is optimal

It all depends on the tasks assigned to the computer and, of course, processor power.

For example, the device has a processor of modest possibilities (for Intel: Atom, Celeron, Pentium or similar), there are no serious tasks - you are limited to surfing the network, watching movies, working with documents, then the optimum size is 4-6 GB.

The next processor, which can be attributed to the middle category (for Intel: Core i3, i5 or similar), is the task - editing photos, videos (perhaps you plan to do this), like to spend the evening at a 3D toy, in the browser window is open 15 and more active tabs, then the recommended amount of 8-12 GB of RAM for you.

You have spent on a powerful, modern processor like Intel Core i7 and higher, you cannot live without games, your work is connected with shooting and editing video, photos, then the recommended amount of RAM should be at least 16 GB.

How to find out the frequency of RAM on a laptop

1. First, we determine the frequency visually. Using the hot keys CTRL + SHIFT + ESC open the "Program Manager". Next "Performance" - "Memory". The frequency is indicated here as speed.
2. Similarly, we get here through the "Start" menu by typing "Program Manager" in the command line.

Using CPU-Z. Open the program, go to the tab "SPD", the column "Max Bandwidth". We look, the frequency value is hidden by brackets.

The program shows the real value of the frequency, manufacturers - effective. Her in Windows we see in the manager.

Important! Almost always, when it comes to frequency, they talk about the effective frequency of the RAM. It is explained by the fact that the clock pulses have a frequency of 800 MHz, information is removed twice during the period. It turns out that the effective frequency is twice the real one.

If we follow this principle, we need to order a bar with a 1600 MHz RAM frequency (the value of 800 MHz obtained in the CPU-Z table is doubled). Now you have all the information in your hands. The decision is yours - add memory or keep everything as it is.
