Is 4GB RAM Enough for Windows 10? Here is the Truth!

Is 4GB RAM Enough for Windows 10? |


Upgrading to new windows always requires the compatible hardware in your laptop or PC to support it. If you lack any crucial component or don’t meet the minimum requirement, your PC won’t be able to run that upgrade smoothly. So, it’s very important to know what actually minimum requirement for Windows 10 is.

RAM stores information that can be accessed quickly by the processor to perform tasks. Without enough RAM your computer will be slow and unable to perform tasks. RAM supports Windows to launch applications and perform background processes. Each Windows have a specific minimum amount of required RAM.

Is 4GB RAM Enough for Windows 10?

Here is the answer:

4GB RAM for Windows 10 is enough to support all its basic features. RAM is a crucial hardware component like the CPU and Hard drive. RAM provides cache storage for Windows to run its programs smoothly. More RAM means more storage and lag-free performance.

If you want to use advanced features or multitask, you should go for more than 4GB RAM. On the other hand, if you are a gamer and use multiple software like streaming or recording applications or heavy editing software, then 8GB or 12GB RAM is recommended.

It’s because 2GB will be allotted to Windows essential system background applications, and the rest of the RAM will be used by your installed applications. But, of course, it also depends on your processor and GPU. So both these components provide additional support to RAM.

So, even if you have 4GB RAM and your system is using 3GB of it, there is a high chance that your PC will get laggy due to less storage for current applications. 

How Much RAM Does a PC With Windows 10 Need?

We recommended at least 4GB of RAM for Windows 10. 2GB is the minimum requirement, but with only 2GB, you might face some performance issues while using RAM-intensive programs or even while playing games. So, if you can afford it, go for 4GB or even 8GB of RAM. It will future-proof your PC.

Your PC’s processor and GPU give extra help to the system to run the operating system. For example, if you have a 1 GHz processor with 4GB RAM, you will most likely face performance issues, but if your processor is 2GHz or higher with 4GB RAM, you will surely see a performance boost. 

In the case of GPU, it has its VRAM, which allows the graphics processing unit to quickly access the display memory. So, it lessens the display burden on RAM. If you are a gamer or into video editing, getting a graphics card with its memory is recommended. 

Here are some key features of 4GB RAM with Windows 10:

Tasks  4GB RAM For Windows 1O
Firmware Support Connect firmware and hardware with each other.
Pro Gaming Windows 10 with 4GB RAM supports all sorts of Pro profile gaming if you have simple GPU support. 
Medium Video Editing You can perform low to medium video editing.
Email, documentation, and managing tasks 4GB is more than enough for such tasks in Windows 10.

Windows 10 System Requirements

System requirements for Windows 10 include hardware capabilities, i.e., processor, RAM, hard drive display (GPU), etc. Here is the list of minimum requirements of Windows 10 provided by Microsoft’s official website. 

Hardware Minimum Requirement
Processor 1GHz or more
RAM 4GB for 64-Bit and 2GB for 32-Bit
Space 16 GB Hard drive space
Display Support Microsoft DirectX 9 graphics device with WDDM driver.

If you’re using an older version of Windows and want to upgrade to Windows 10, here are some points you need to know before the upgrade. 

First, check if your PC meets the minimum requirements or not. You can see it from the official website or Windows update center in your current Windows. You can also manually check each hardware component. If your PC doesn’t meet the minimum requirements, you need to upgrade your hardware too.

To check RAM, simply go to property settings of “This PC,” and you will see there installed and usable RAM of your PC/Laptop. You will find the processor hertz there too. To view the graphic card or integrated graphics, open the DirectX. To do this, write “DXDIAG” in the Windows search panel and open the application. 

6 Steps To Optimize Slow Windows 10 with 4GB RAM

If you’re experiencing a slowdown on your Windows 10 device, don’t worry; you’re not alone. Many users have reported that their devices are running slowly after upgrading to Windows 10, even if they have 4GB of RAM. There are many possible causes for this problem, including hardware and software.

First, you have to determine whether the hardware or the software is causing the issue. Then, if it’s the hardware, you have to replace it, or if it’s any application or program, you have to reinstall it. Here are some common issues of Windows 10, even with 4GB RAM, and how you can resolve them. 

1. Overloaded Cache

Overloaded RAM cache always hurdles and restricts the applications from running smoothly and causes laggy performance. If RAM storge is full with temporary files, then the newly launched application won’t be able to provide maximum output as their processing files will fail to launch timely. 

To remove the RAM cache, you can use in-Windows applications or third-party software like CleanMemAdvanced system optimizer, RAMRush, Mz RAM Booster, etc. All these applications have a user-friendly interface and are easy to use. These applications will remove the cache in seconds, giving a boost to your Windows. 

2. Startup Apps

Startup apps depend on your RAM. If you have 4GB RAM, it can take time to load all the apps. So, it is good to disable the startup apps you don’t use frequently. It will lessen the load on your RAM and make space for new cache files. 

To do that, press the “Ctrl+Alt+Del” key at the same time and open the task manager. Next, go to the startup tab, select the extra and unusable apps, and right-click on them. Now select “Disable” from the file.

3. Windows Update

If your PC requires Windows 10 update, do it as soon as possible. Delay in Windows 10 update causes many performance issues. New updates always fix the previous bugs in Windows. Go to the start search bar, type “Windows Update Settings,” and open the settings to check the update. Now click on “check for updates.”

If your PC starts the update, sit back and relax until complete. Any issue in the update also leads to a PC slowdown.

4. Run Disk Cleanup 

Disk cleanup is an inbuilt Windows 10 application that helps clean all the unwanted and temporary files from your system. These junk files always use extra space in RAM and hard disk. To run Disk Cleanup, go to the start search box and type “Disk cleanup,” and open it. Now select the drive you want to clean and start the process.

5. Delete Unwanted Programs 

If you have installed many programs on your Windows 10 PC and started working slowly, it is good to delete unwanted and rarely used apps. These apps take the cache and extra storage on your devices. These apps always use extra space in RAM, which can lead to a slowdown. 

To delete the apps, go to the control panel and open “Uninstall a program.” Now select the apps you want to delete and right-click on them. Now select uninstall from the menu to uninstall it.

6. Update Window 10 Drivers

Windows 10 is a simple, user-friendly operating system requiring frequent driver updates. Either these drivers support the firmware or the hardware. Even if you have compatible hardware like RAM and processor, outdated drivers will make it work slowly. So always update to the latest version of drivers.


In short, 2GB is the minimum requirement for Windows 10, but we recommend at least 4GB for better performance. With less than 4 GB of RAM, you will experience lag and slowdowns, especially when running multiple programs or opening large files. If you regularly use resource-intensive programs or play games, you may want to consider upgrading to 4GB or more of RAM.
