How to Increase RAM in PC Using Pen Drive (Full Guide)
If you want to increase RAM in PC using pen drive, Windows provides a built-in feature called ReadyBoost that can help improve performance on low-end systems without upgrading physical hardware.
This is where a simple built-in Windows feature called ReadyBoost comes into play. It allows you to use a pen drive or USB flash drive as additional memory cache to improve system performance. Although it does not replace actual RAM, it can help speed up older or low-end systems.

Many users search for how to increase RAM in PC using pen drive because it is one of the easiest ways to boost system performance without spending money. In this guide, we will explain step-by-step how to increase RAM in PC using pen drive using the ReadyBoost feature in Windows.
What is ReadyBoost in Windows?
ReadyBoost is a feature introduced in Windows that uses external flash storage like USB drives, SD cards, or pen drives to act as a caching system for your computer. Instead of relying only on slow hard disk access, Windows stores frequently used data in the faster flash memory of your USB device.
This helps reduce loading time and improves responsiveness, especially in systems that have low RAM or are using traditional hard disk drives (HDDs).
However, it is important to understand that ReadyBoost does not increase your actual RAM. It simply acts as a temporary performance booster for storage caching.
How Does Pen Drive Work as Virtual RAM?
When you enable ReadyBoost, Windows creates a special cache file on your pen drive. This cache stores frequently accessed system files and application data. Since USB flash storage is faster than traditional HDDs, the system can retrieve this data more quickly.
This reduces the workload on your physical RAM and hard drive, which can make your system feel smoother in day-to-day tasks like browsing, file opening, and light multitasking.
Think of it as a “helper memory” that supports your system rather than replacing real RAM.
When Should You Use ReadyBoost?
ReadyBoost is not useful for every computer. It works best in specific situations where system performance is limited by storage speed rather than CPU or RAM capacity.
You should consider using ReadyBoost if:
- Your PC has 2GB to 4GB RAM
- Your system uses a traditional HDD instead of SSD
- Your computer feels slow during basic tasks
- You cannot upgrade RAM immediately
If you already have an SSD and 8GB or more RAM, ReadyBoost will not provide noticeable improvement.
Requirements Before Using Pen Drive as RAM
Before setting up ReadyBoost, make sure you have the following requirements ready.
- A USB pen drive with at least 1GB storage (4GB or more recommended)
- A working USB port (USB 3.0 gives better performance)
- Windows operating system (Windows 7, 8, 10, or 11)
- A computer using HDD storage (not mandatory but ideal)
How to Increase RAM in PC Using Pen Drive
Follow these simple steps carefully to enable ReadyBoost on your computer.
Step 1: Insert your pen drive into the USB port of your computer.
Step 2: Open “This PC” or “My Computer” and locate your USB drive.
Step 3: Right-click on the pen drive and select “Properties”.
Step 4: In the properties window, click on the “ReadyBoost” tab.
Step 5: Select the option “Use this device”.
Step 6: Adjust the slider to allocate space for system caching. It is recommended to use maximum available space for better performance.
Step 7: Click “Apply” and then “OK”. Windows will now configure the device for ReadyBoost.
Once completed, your pen drive will start working as a performance booster for your system.
What Happens After Enabling ReadyBoost?
After activation, Windows automatically starts using the pen drive for caching system files. You may notice improvements in:
- Faster application loading
- Reduced system lag
- Better responsiveness during multitasking
- Improved file browsing speed
However, the improvement is subtle and mostly noticeable on older systems rather than modern high-performance PCs. This method to increase RAM in PC using pen drive is mainly useful for older systems with low memory and traditional hard drives.
Limitations of Using Pen Drive as RAM
While ReadyBoost is useful in some cases, it also has limitations that you should understand before relying on it.
- It does not replace physical RAM
- It offers limited performance improvement
- It is ineffective on SSD-based systems
- USB speed directly affects performance gains
- Heavy tasks like gaming or video editing will not improve significantly
Because of these limitations, ReadyBoost should be considered a temporary solution, not a permanent upgrade.
ReadyBoost vs Real RAM Upgrade
Many users get confused between ReadyBoost and actual RAM upgrades. The difference is very important.
Real RAM is physical memory installed inside your computer. It directly affects performance and multitasking capability. More RAM means better performance for heavy applications.
ReadyBoost, on the other hand, only improves caching speed. It does not increase memory capacity. It simply helps your system access data faster in certain conditions.
If your goal is serious performance improvement, upgrading RAM is always the better option.
How to Disable ReadyBoost
If you no longer want to use your pen drive as virtual memory, you can easily disable it.
- Insert the pen drive into your system
- Open Properties of the USB drive
- Go to the ReadyBoost tab
- Select “Do not use this device”
- Click Apply and OK
After this, your pen drive will return to normal storage mode.
FAQs
1: Can I really increase RAM in PC using pen drive?
You cannot increase physical RAM, but you can use a pen drive with ReadyBoost to improve system performance. It works as cache memory to help speed up slow computers.
2: Does ReadyBoost work on Windows 10 and Windows 11?
Yes, ReadyBoost works on Windows 10 and Windows 11. However, it gives better results on older PCs that use HDD storage instead of SSD.
3: How much RAM can ReadyBoost replace?
ReadyBoost does not replace RAM. It only uses USB storage as additional cache memory to improve system responsiveness.
4: Which pen drive is best for ReadyBoost?
A fast USB 3.0 pen drive with at least 4GB storage is recommended for better performance.
5: Is ReadyBoost useful for gaming or heavy software?
No, ReadyBoost does not significantly improve gaming or heavy software performance. It is mainly useful for basic speed improvements on low-end systems.
Final Thoughts
Using a pen drive as virtual RAM through ReadyBoost is a simple and useful trick for improving performance on older computers. It is especially helpful for users who are unable to upgrade hardware immediately.
However, it is important to understand that this method only provides a minor boost. For long-term performance improvement, upgrading to SSD storage and increasing physical RAM is the most effective solution.
If used correctly, ReadyBoost can still be a helpful temporary solution for boosting everyday PC performance without spending money.
