随机存取存储器(Random Access Memory)或RAM是当今计算机或智能手机中最受欢迎的组件之一。它决定了您的设备性能有多好或多快。RAM最重要的方面是它是用户可升级的，让用户可以根据自己的要求自由地增加计算机中的RAM 。低到中等(Low to moderate)用户选择4 到 8 GB RAM(4 to 8 GB RAM)容量，而在重度使用场景中使用更高容量。在计算机的发展过程中，RAM也以多种方式发展，尤其是RAM的类型(RAMs)已经出现。您可能很想知道如何分辨您拥有的RAM类型。(RAM)我们为您提供了一份有用的指南，它将教您有关不同类型的RAM(RAMs)以及如何检查Windows 10中的(Windows 10)RAM类型。所以，继续阅读！
如何在 Windows 10 中检查 RAM 类型(How to Check RAM Type in Windows 10)
Windows 10 中的 RAM 类型是什么？(What are RAM Types in Windows 10?)
有两种类型的 RAM：静态和动态(Dynamic)。两者的主要区别在于：
- 静态RAM(RAMs) ( SRAM(SRAMs) ) 比动态 RAM(Dynamic RAMs) ( DRAM(DRAMs) )更快
- (SRAMs)与DRAM相比， (DRAMs)SRAM提供更高的数据访问速率和更低的功耗。
- 制造SRAM(SRAMs)的成本远高于DRAM(DRAMs)
DRAM，现在是主存的首选，经历了自己的转型，现在是第 4 代RAM。在数据传输率和功耗方面，每一代都是上一代的更好迭代。请(Please)参阅下表了解更多信息：

How to Check RAM Type in Windows 10
Random Accеss Memory or RAM іѕ one of the most sought-аfter componеnts present in the computer or smartphone today. It determines how good or quick the performance of your device is. The most important aspect of RAM is that it is user-upgradable, giving userѕ the freedom to inсrease the RAM in their computer befitting to their requirements. Low to moderate users opt for somewhere between 4 to 8 GB RAM capacity, while higher capacities are used in heavy usage scenarios. During the evolution of computers, RAM also evolved in many ways especially, the types of RAMs that have come into existence. You may be curious to learn how to tell what type of RAM you have. We bring to you a helpful guide that will teach you about different types of RAMs and how to check RAM type in Windows 10. So, continue reading!
How to Check RAM Type in Windows 10
What are RAM Types in Windows 10?
There are two types of RAMs: Static and Dynamic. The main differences between the two are:
- Static RAMs (SRAMs) are faster than Dynamic RAMs (DRAMs)
- SRAMs provide a higher data access rate and consume less power when compared to DRAMs.
- Cost of manufacturing SRAMs is much higher than that of DRAMs
DRAM, now being the first choice for primary memory, underwent its own transformation and it is now on its 4th generation of RAM. Each generation is a better iteration of the previous one in the terms of data transfer rates, and power consumption. Please consult the table below for more information:
| Generation |
Speed range (MHz) |
Data transfer rate (GB/s) |
Operating voltage(V) |
| DDR1 |
266-400 |
2.1-3.2 |
2.5/2.6 |
| DDR2 |
533-800 |
4.2-6.4 |

Latest generation DDR4: It took the industry by storm. It is the most power-efficient and the fastest DRAM available today, becoming the first choice of both, the manufacturers and the users. It is an industry standard today, to use DDR4 RAM in computers being manufactured recently. If you want to learn how to tell what type of RAM you have, simply, follow the methods listed in this guide.
Method 1: Using Task Manager
Task manager is your one-stop destination to know everything about your computer. Apart from the information about the processes running on your computer, Task manager also helps you monitor the performance of hardware and peripherals installed on your computer. Here’s how to tell what type of RAM you have:
1. Open Task Manager by pressing Ctrl + Shift + Esc keys simultaneously.
2. Go to the Performance tab and click on Memory.
3. Among other details, you will find Speed of your installed RAM in MHz (MegaHertz).
Note: If your computer runs on DDR2, DDR3 or DDR4 RAM, you might find the RAM generation from the top right corner directly depending on the device manufacturer and model.
How to check laptop RAM type DDR2 or DDR3? If the speed of your RAM falls between 2133-3200 MHz, it is DDR4 RAM. Match other speed range with the table provided in the Types of RAMs section at the beginning of this article.

Method 2: Using Command Prompt
Alternately, use Command Prompt to tell what type of RAM you have in your computer, as follows:
1. Click on Windows search bar and type command prompt then, click on Run as administrator.
2. Type the following command and press the Enter key.
wmic memorychip get devicelocator, manufacturer, partnumber, serialnumber, capacity, speed, memorytype, formfactor
3. From the given information, Find the Memory Type and note the numerical value it denotes.
Note: You can view other details like RAM capacity, RAM speed, manufacturer of RAM, serial number, etc. from here.
4. Refer to the table given below to determine the type of RAM installed in your computer.

Method 3: Using Windows PowerShell
Command Prompt has been an important tool in the Windows ecosystem since the time it was introduced in 1987. It houses and runs many commands which could answer the query: how to check laptop RAM type DDR2 or DDR3. Unfortunately, some of the commands available are too old to keep up with otherwise updated Windows 10 and cannot recognize DDR4 RAM. Hence, Windows PowerShell would be a better option. It uses its own command line which will help do the same. Here’s how to check RAM type in Windows 10 using Windows PowerShell:
1. Press Windows key, then type window powershell and click on Run as Administrator.
2.Here, type the given command and hit Enter.
Get-WmiObject Win32_PhysicalMemory | Select-Object SMBIOSMemoryType
3. Note the numerical value that the command returns under SMBIOS MemoryType column and match the value with the table given below:
| Numerical Value |
Type of RAM installed |
| 26 |
DDR4 |
| 25 |
DDR3 |
| 24 |
DDR2 FB-DIMM |
| 22 |

Method 4: Using Third-party Tools
If you do not wish to use the above methods on how to check RAM type in Windows 10, you could opt for a third-party application called CPU-Z. It is a comprehensive tool that lists all the details you want to find about your computer hardware and peripherals. Additionally, it provides options to either install it on your computer or to run its portable version without installation. Here’s how to tell what type of RAM you have using CPU-Z tool”
1. Open any web browser and go to CPU-Z website.
2. Scroll down and choose between SETUP or ZIP file with your desired language (ENGLISH), under CLASSIC VERSIONS section.
Note: The SETUP option would download an installer to install CPU-Z as an application on your computer. The ZIP option would download a .zip file that consists of two portable .exe files.
3. Then, Click on DOWNLOAD NOW.
4A. If you downloaded the .zip file, Extract the downloaded file in your desired folder.
4B. If you downloaded the .exe file, double click on the downloaded file and follow the on-screen instructions to install CPU-Z.
Note: Open the cpuz_x64.exe file if you are on a 64-bit version of Windows. If not, double click on cpuz_x32.
5. After installing, launch the CPU-Z program.
6. Switch to Memory tab to find the type of RAM installed on your computer under General section, as highlighted.
