Why does Photoshop not have enough RAM?
1. Use RAM optimizing software
The entire RAM that is installed on your computer is shared between Windows and each and every other program that is running.
Even applications that run in the background, which you don’t interact with, consume RAM.
If there are too many running programs or if some of them encounter problems, not enough memory will be available for running Adobe Photoshop. Therefore, we recommend using a RAM optimizer for Windows 10.
You will be able to adjust your operating system, hardware, and program settings to ensure that Photoshop runs consistently and at maximum performance on your computer.
A RAM optimizer should do the job if Photoshop is running slower than expected on your machine, or if you’re having system freezes, lags, or delays.
2. Increase allowed RAM usage
- Open Photoshop.
- Open Edit, click on Preferences and then access Performance.
- Set the value to 100% of RAM by using the slider.
- Confirm the changes.
- If you are unable to assign 100% to Memory Usage, set it to 96% and try again.
3. Disable background applications
- In the Windows Search bar, type msconfig and open System Configuration.
- Under the Services tab, check the Hide all Microsoft services box.
- Click Disable all to disable all active third-party services.
- Confirm changes and try starting Photoshop again.
4. Edit the Registry entry
- Press Windows key + R to open the Run command line.
- In the command line, type Regedit and press Enter.
- Navigate to
ComputerHKEY_CURRENT_USERSoftwareAdobePhotoshop90.0
. The 90.0. part means that the Photoshop version in this example is Photoshop CC 2015. The values change for different versions. - Right-click on the empty area of the right pane and choose New and select the DWORD (32-bit) Value.
- Name the newly created DWORD OverridePhysicalMemoryMB and assign its value to 2400. Make sure that Hexadecimal value is toggled and not Decimal.
- Save changes, start Photoshop and look for improvements.
5. Reinstall Photoshop
- Search for Control Panel from the Start menu and open it.
- Choose Uninstall a program.
- Uninstall Photoshop.
- Navigate to Program Files on the system partition and delete the remaining folder.
