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 you 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. If there is not enough memory to complete the task, its work will slow down, it begins to “freeze and slow down”. This is a consequence of the fact that the machine is trying to compensate for its shortcoming by using read-only memory (ROM) or storage.

Important! We warn you - a lack of RAM, undoubtedly, slows down the device’s performance, but not only it is to blame - options are possible. Read the article, then decide.

How to find out the characteristics of RAM in a laptop

Consider ways to determine the characteristics of RAM

• Visual: We turn to the device properties. Click on “My Computer” - select “Properties”. We are looking for the right line, look at the RAM capacity. We use the "hot key combination" - we type Win + R. In the line that opens, type dxdiag. We find the tab "System". We look at the physical characteristics of the memory.

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

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

Bandwidth (PC3–12800) corresponds to DDR3 RAM with a maximum speed of 12,800 Mb / s. We calculate the frequency of the OP: the maximum speed of 12,800 Mb / s is divided by 8. We get a frequency equal to 1,600 MHz.

• Program: If superstition or a manufacturer’s guarantee does not allow you to disassemble the new device, you can determine the parameters of the RAM 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. We launch the application. In the pop-up window (warning about the trial, 30-day version), click OK. Here is a program window, divided into two parts. In one - PC components, in the second of their characteristics.
3. Open the "System Board" - the SPD tab. Here is the complete information about the installed RAM.

Which volume is optimal

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

For example, the device has a modest processor (for Intel: Atom, Celeron, Pentium or similar), no serious tasks - you are limited to surfing the net, watching movies, working with documents, then the optimal amount 4-6 GB.

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

You spent on a powerful, modern processor such as Intel Core i7 and higher, you can not live without games, your Since work is connected with shooting and editing videos, photos, 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 CTRL + SHIFT + ESC hot keys, open the “Program Manager”. Further “Performance” - “Memory”. Frequency is indicated here as speed.
2. Similarly, we get here through the Start menu by typing "Program Manager" on the command line.

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

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

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

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