The “Not Enough Memory (RAM)” error in Photoshop is a nuisance to users, especially when processing large files. Optimizing RAM and adjusting appropriate settings helps improve performance and reduce lag. Below, sadesign lists methods to fix this error to work with Photoshop more smoothly.
1. Causes of the error “Not Enough Memory (RAM)” in Photoshop
The “Not Enough Memory (RAM)” error in Photoshop usually occurs when the software does not have enough RAM to process the tasks it is performing. Photoshop requires a significant amount of RAM to process images, especially when working with high-resolution files. When the software cannot access enough RAM, the “Not Enough Memory (RAM)” error appears. Some common causes include:
Limited RAM : Photoshop may have limited RAM access due to default settings or suboptimal configuration. Photoshop is a complex image processing software that requires a large amount of RAM to operate smoothly. When you work with high-resolution files, many layers, or use heavy filters and effects, Photoshop will consume a lot of RAM. If your system does not have enough RAM, Photoshop will have difficulty processing data, resulting in the "not enough memory" error.
Scratch Disk is full : The temporary drive (Scratch Disk) acts as virtual memory when RAM is not enough, if the capacity of this drive is low, an error may appear.
Working files are too large : Documents with many layers, high resolution or using many complex effects make Photoshop consume a lot of RAM.
Older versions of Photoshop : Some older versions of Photoshop are not optimized, causing them to consume more RAM than necessary.
Background applications take up RAM : Other software running on the computer also uses RAM, causing Photoshop to not have enough memory to operate.
Unoptimized Photoshop settings:
Photoshop has many performance-related settings, such as RAM allocation, Scratch Disks settings, and History States settings. If these settings are not configured properly, Photoshop may use RAM inefficiently, resulting in low RAM errors.
Use multiple layers and complex effects:
Each layer and effect you add to a Photoshop file increases the amount of RAM needed. Complex projects with many layers and effects will consume a lot of RAM.
Opening too many Photoshop files at once:
Each open Photoshop file uses a portion of your RAM. Having too many files open at once can quickly exhaust your system's RAM.
Other applications that are taking up RAM:
Other applications running on your computer also use RAM. If you have many applications running at the same time, especially RAM-hungry applications like web browsers or video editing software, Photoshop may not have enough RAM to function.
Software or driver error:
Errors in Photoshop software or graphics card drivers can also cause low RAM errors. Outdated or corrupt graphics card drivers can cause problems when Photoshop tries to use the graphics card's resources, resulting in low RAM errors.
2. How to check and optimize RAM capacity for Photoshop
To check and optimize RAM capacity for Photoshop, you need to perform the following steps:
Check your computer's current RAM capacity:
To check and optimize your RAM for Photoshop, you first need to determine how much RAM your computer currently has. This can be done by accessing the "System Information" or "Task Manager" section of your operating system.
On Windows: Open Task Manager (Ctrl + Shift + Esc), go to the Performance tab, and view the Memory information.
On macOS: Click the Apple icon, select About This Mac, and view the Memory information.
Once you have determined your RAM capacity, you should check your RAM usage while running Photoshop to see how much resources the software is consuming. If you find that your RAM is not enough, you can optimize it by adjusting the performance settings in Photoshop, turning off unnecessary applications running in the background, or upgrading your RAM to ensure the best performance!
Install 64-bit version of Photoshop: To check and optimize RAM capacity for Photoshop, using the 64-bit version of the software is an effective solution.
The 64-bit version of Photoshop can use more RAM than the 32-bit version. If you are using the 32-bit version, upgrade to the 64-bit version to take full advantage of your system's RAM.
This version allows you to take full advantage of the processing capabilities of your operating system and hardware, especially when working with large files or complex projects.

Increase Virtual Memory: To check and optimize RAM capacity for Photoshop, an effective solution is to increase the Virtual Memory capacity on your system.
Virtual RAM uses hard drive space as temporary memory when physical RAM is not enough. Increasing the amount of virtual RAM can help Photoshop run more smoothly.
On windows you can find this customization section, by typing in the windows search bar "Adjust the appearance and performance of windows". To do this, you can access the operating system settings, adjust the virtual memory size according to your needs and make sure that the selected drive has enough free space. This optimization not only helps Photoshop run smoother but also increases work efficiency when processing large graphic files.
Prioritize RAM allocation for Photoshop: To check and optimize RAM capacity for Photoshop, you need to make sure that the software is allocated enough resources to operate efficiently.
In Photoshop, you can specify how much RAM Photoshop will use. Open Preferences (Ctrl + K), go to the Performance tab, and adjust the Memory Usage slider.
First, go to "Preferences" in Photoshop, then select "Performance." Here, you can adjust the slider to increase or decrease the amount of RAM that Photoshop prioritizes, depending on the total amount of RAM on your system. For optimal performance, it's recommended to allocate about 70-85% of your RAM to Photoshop, especially when working with large files or using many layers. Also, make sure that other applications aren't taking up too many system resources while Photoshop is running. Proper RAM management will help improve processing speed and reduce lag when working on the software.
Set up Scratch Disks properly:
To check and optimize your Photoshop RAM, you need to make sure that the software is configured to match your system resources. One important way is to set up Scratch Disks properly. Scratch Disks are hard drive spaces that Photoshop uses as temporary memory. Choose an SSD with high read/write speeds to optimize performance. In the Performance section of Preferences, you can select the drive as your Scratch Disk.
Additionally, you should allocate an optimal amount of RAM to Photoshop in Preferences > Performance, usually around 70-85% of your system's total RAM. Taking these steps will help improve performance and reduce lag when working on large projects.
