If you needed to find out how much random access memory (RAM) is installed on your computer or laptop, and also to get additional information about it: current frequency, number of occupied RAM slots, type, model or voltage. This can be done either by the built-in system tools or using third-party free programs (in the latter case, you can get more detailed information).
This guide details various methods for determining how much GB of RAM is installed on a PC or laptop, as well as some additional information that may be useful. If you are interested in how to find out how much memory your computer supports, I touched on this topic in a separate article: How to increase the RAM of a laptop (also relevant for desktop computers). Also useful: Is it possible to put RAM of different sizes, frequencies, and voltages.

Determining the amount of RAM in a computer or laptop using Windows
Windows 10, 8.1 and Windows 7 provide simple utilities for viewing computer settings, including hardware specifications regarding the amount of RAM. First about the method for all the latest versions of the OS, and then a separate method for Windows 10.
- Press the WinR keys on the keyboard (Win key is the key with the OS logo), the Run dialog box will open, enter into it msinfo32 and press Enter.
- A system information window will open. In it, in the first tab, you will see the item “Installed RAM” and its size in GB. This is information about how much RAM is on your computer.
Detailed information regarding the hardware characteristics of the installed RAM is not available here. But often for a novice user this information is enough.
If you have installed Windows 10, then you can use the following method and get more detailed information about the installed RAM memory:
- Open the task manager (for this you can right-click on the “Start” button and select the appropriate item in the context menu that opens). If at the bottom of the task manager window you see the “Details” button, click on it. If not, go to the Performance tab.
- On the Performance tab, select Memory. As a result, in the upper right corner you will see the total amount of installed RAM and its type (DDR4, DDR3, etc.), and in the column at the bottom right (it may be cropped with a small window size), the frequency (in the “Speed” section, and the number used memory slots.
Keep in mind that information about the number of slots used may turn out to be incorrect (especially for laptops): sometimes, if there are only 2 slots of RAM, the system “sees” 4.
Using third-party programs to find out how much GB of RAM is installed
Third-party programs for determining the amount of memory and other characteristics of a computer are good in that they allow you to get more detailed information about various RAM parameters. There are many different programs for viewing the characteristics of a computer, but in the context of this article I would recommend using a free CPU-Z, which you can download as an installer or portable version in a ZIP archive from the official website https://www.Cpuid.com/softwares /cpu-z.html
After starting the program, go to the “Memory” tab. Here in the “General” section you will see basic information about the installed memory (I don’t specifically touch on some parameters as superfluous in the context of the article):
- Type. Type of memory.
- Size. The total size of RAM.
- Channel. In what mode the memory works. Usually: Single (single-channel) or Dual (two-channel).
- NB Frequency. The current frequency of the memory controller (not the same as the memory frequency and not quite for beginners). Sometimes an item may not be active (on older systems) and may not display information.
You can see the current current memory frequency in the Timings. DRAM Frequency section. It can “jump” and be half as much as the declared frequency in the characteristics of your RAM module. This is normal (we get a frequency twice as high due to the dual-channel mode, but the actual frequency will still be displayed in this field), small the difference from the “round” numbers to the smaller side is also normal and depends mostly on the processor of the computer or laptop.
Separately, on the SPD tab in CPU-Z, by selecting a specific slot in the upper left, you can get information about the characteristics of each installed memory module: from the main (for beginners). Type, maximum frequency, manufacturer, model of the memory module (in the Part Number section) , memory module capacity, voltage (at the bottom, in the table, under Voltage).
There are other programs that provide equally detailed information. Of the popular, but not completely free. AIDA64.
Installed memory in BiOS or UEFI of a computer or laptop
Information about the installed RAM can also be found in the BiOS (UEFI) of your PC or laptop (see How to access BiOS / UEFI in Windows 10).
In BiOS of different manufacturers and different versions, this information is in different locations: sometimes on the main page (Main), sometimes in separate sections like System Information or RAM (DRAM) Configuration. Information on the amount of installed memory, frequency and voltage (as well as additional information and settings) is usually available on a PC in these sections.
And a simple that clearly shows the first two ways to find out how much RAM is installed on your system.
I hope the instruction was helpful. If something is not completely clear, I am waiting for your comments.
