Can I Use My SD Card as RAM on Android and Windows?
Consequently, Android and Windows users with low RAM have begun asking, "Can I use my SD card as RAM?" This is possible by setting up a swap memory or virtual RAM with your SD card and using it to run idle programs on your Android or Windows computer, thereby freeing up RAM.
Although this isn't exactly the same as expanding your RAM, some refer to it as a RAM increment since it functions as an additional RAM. However, you'll need a best-class SD card and root your Android handset to use this workaround. This article will explore how to use your SD card as RAM on Windows and Android.
Can I Use My SD Card as RAM on Android
Android users frequently question whether they can actually use an SD card as RAM on their phone, but the answer is yes. As is well known, certain Android devices have extremely little RAM, making it difficult or even impossible to run specific applications, such as games.
Fortunately, you can still create a virtual RAM space on your Android phone with the help of a high-class SD card—at least class 4—which will be helpful for the smooth running of these applications on your phone. A third-party app and root access on your Android device will load this virtual memory, which we commonly refer to as swap memory, into your SD card.
To allow your phone more room to run other applications more effectively, idle apps are loaded into the virtual memory once this swap memory is created on the available space on your SD card. Your phone's processor will operate more quickly due to the reduced load on the native RAM thanks to this extra RAM storage.
In other words, you can always use an SD card to boost your phone's RAM as long as you're using a top-tier SD card, have rooted your Android smartphone, and your Android device supports this function.
Can I Use My SD Card as RAM on Windows 10
Windows natively permits the use of a portion of the partition space as virtual RAM in order to support the smooth running of more programs on Windows computers. On Windows 10, you can use an SD card as virtual RAM in the same way you do with your hard drive; so, the answer to the question "can I use an SD card as RAM on Windows 10" is yes.
Creating virtual RAM with an SD card on Windows 10 actually works similarly to how we described it for Android devices. When your computer's original RAM runs out, the virtual RAM kicks in to help store data for your processor and enable efficient application running.
Windows 10 makes it relatively simple to use an SD card as RAM, but you first need to format the SD card FAT32. In a later section of this article, the steps for using an SD card as RAM on a Windows PC will be covered.
Format SD Card Before Using It As RAM
Prior to using your SD card as RAM, you must format it. Many people only know how to use Windows File Explorer for this purpose, but this tool is too basic and has many limitations.
Qiling Disk Master is a robust and well-used tool for a variety of functions, including formatting SD cards. The SD card formatting process with this tool is efficient, simple, and safe.
This tool essentially serves as an all-in-one disc management that can be used for simple and complex functions. Therefore, before using your SD card as RAM, you might utilize Qiling Disk Master to format it.
You may format the SD card by following the steps down below:
Step 1. Launch Qiling Disk Master, right-click the partition on your external hard drive/USB/SD card which you want to format and choose the "Format" option.
Step 2. Assign a new partition label, file system (NTFS/FAT32/EXT2/EXT3/EXT4/exFAT), and cluster size to the selected partition
Step 3. Click the "Proceed" button to start formatting your external hard drive/USB/SD card.
Step 4. In the Warning window, click "Yes" to continue.
Moreover, you can copy OS data to another HDD or SSD with the Qiling Disk Master and convert FAT32 to NTFS. This free tool can also resize, create, delete, or expand partitions and check for a disc, file system types, and bad sector faults.
Now, it's time to learn how to use SD card as RAM in Android and Windows.
How to Use SD Card as RAM in Android
There are several methods you can utilize to use SD cards as RAM in Android, and below are the top ones:
- Method 1. Use ROEHSOFT RAM Expander
- Method 2. Use RAM Manager Pro
- Method 3. Manually Partition the SD card
Method 1. Use ROEHSOFT RAM Expander
One of the greatest options for adding swap memory to the SD card on your Android phone is the ROEHSOFT RAM Expander. This method requires rooting, just like other methods for increasing RAM on Android. The ROEHSOFT RAM Expander costs about $5 on the Google Play Store.
However, the tool is not compatible with all Android phones, so you need to test your phone using MemoryInfo & Swapfile Check. Simply install the software, run it, tap the Start RAMEXPANDER Test Here button, and then choose the swap path.
The app will notify you with a Congratulations message if your device runs the test properly. This shows that your device can use this swap file, and you can use the steps below to load the swap file into your SD card and begin using it as virtual RAM.
Step 1. Download and install ROEHSOFT RAM Expander.
Step 2. Give the app root access when you launch it and wait for it to load fully.
Step 3. Now, check the Autorun box so the app will run automatically when your phone boots up.
Step 4. Click on the Optimal Value option to set the paging file to the optimal setting. Also, you can manually set the swap memory to what you want by sliding the SwpPart slider.
Step 5. Tap on the Swap Activ button and select the path or partition for the swap afterward.
The process of creating the swap memory will start, and you will begin to feel the difference when it finishes.
Method 2. Use RAM Manager Pro
Another method you can use to make your SD an extra RAM in Android is the RAM Manager Pro. This tool has both basic and paid versions, but only the paid version can perform this function.
