How To Check if Your RAM is ddr3 or ddr4

You might be wondering why we need RAM? Why does the CPU not access files directly from the hard drive? This process of accessing program files directly from the hard drive is very difficult for the CPU, and if this process is followed, it would very adversely affect the system’s performance.

RAM becomes important because it organizes the files that we want to run systematically and makes it very fast and easily accessible to the CPU so that the CPU doesn’t have to go to the hard drive and search for the respective programs all the time.

Different RAMs are available in the market. In the series of RAMs, ddr4 is the latest one, and ddr3 is the one that was used before ddr4.

This article majorly talks about methods by which you can check whether your Windows has a ddr3 or ddr4 variant of RAM, but before that, let us get to know the differences between ddr3 and ddr4 Ram.

Difference Between ddr3 and ddr4 ram

ddr3 ram ddr4 ram
Slow as compared to ddr4 Faster than ddr3
Consumes 1.5 volt battery Consumes 1.2 volt battery
Its maximum data rate hardly touches 1 GHz Has maximum data rate of 1.6 GHz
A single memory chip of the ddr3 variant has a maximum capacity of 8 Gb, so the topmost capacity of your computer could be made 32 Gb since there are 4 RAM slots. A single memory chip of the ddr4 variant can be made of capacity anywhere between 2 and 16 Gb, so the topmost capacity of your computer could be made 64 Gb.
Both work similarly when it comes to gaming. Both work similarly when it comes to gaming.
Overall less efficient and less costly than ddr4. Overall more efficient and more costly than ddr3.

How to check whether your computer has ddr3 ram or ddr4 ram

To determine the variant of RAM that is working in your computer system, you can follow the steps of any of the methods mentioned below.

Method 1

  1. Open your favorite browser and search for “cpu z” and click on the first link that appears.
    OR
    Click on the following link – https://www.cpuid.com/softwares/cpu-z.html
  2. From the page that opens, download the ZIP file. Go to the downloads folder, right-click on the file and extract the ZIP file by clicking on the ‘extract all’ option.
  3. Once the files in that ZIP folder are extracted, go to the ‘cpuz_x64.exe’ file. This will open the ‘cpuid’ software. Once the software window is open, go to the ‘Memory’ tab, and there, under ‘general’, you will find ‘Type’, and there you can see which type of RAM is there on your system.

Method 2

  1. Go to the command prompt of your laptop/computer and type the following command: –
    wmic memorychip get memorytype, smbiosmemorytype
    Compare the results you got with the following key, and you can easily determine your memory type.
    20 for ddr and ddr1
    21 for ddr2
    24 for ddr3
    26 for ddr4

Method 3

You can also identify your RAM type by physically looking at the RAM in your system and analyzing it.

  1. Your RAM card would have a sticker on it, and the specifications of your RAM, including the RAM type, would be mentioned on it. DDR RAM would have an elongated IC or Integrated Circuit, i.e., it would touch both the top and the bottom of the RAM.
  2. DDR2 RAM has ICs which are bigger than DDR3 in size but are smaller than DDR1. As new generations come, the size of integrated circuits keeps on decreasing, and their efficiency and power keep increasing. DDR3 has ICs smaller than DDR1 and DDR2. They are almost in a square shape.
  3. In DDR4, the size of ICs is almost the same as that of DDR3, but here, the ICs are arranged in two rows.

Method 4

NOTE: This method might not work for all Windows operating versions.

  1. Right-click on the taskbar from your home screen. Click on ‘Task Manager. If you see a small window with a list of 5-6 options, you need to click on ‘More Details’ at the bottom of the window.
  2. In the bigger window that opens and shows all the tasks in detail, click on the ‘Performance’ tab. From the panel on the left, select ‘Memory’, and on the left-hand side of the window, you will see the memory and the type of DDR RAM running on your system. Please note that you will only be able to see the RAM version through this method if you have the older version of the Windows 10 operating system.

Being aware of the specifications of your computer or laptop can turn out to be very beneficial in a lot of scenarios. Knowing about your device is important, from troubleshooting small problems to making out the best use of your system.

You can check what type of RAM is there in your computer or laptop by following the steps in any of the methods mentioned above; knowing the RAM type helps particularly in situations like if you want to upgrade your RAM or if you are facing RAM related issues and you want to troubleshoot and solve them by yourself.

In any case, knowing about your device is advised.
