Photoshop users have reported a variety of issues on Windows 10 concerning Photoshop physical memory usage and management. Namely, it seems that a lot of them, in a variety of instances, get a variation of the Not enough RAM Photoshop error. This occurs on startup and sometimes while accessing tools. Once it appears, it prevents any and all operations.

Either way, if you are stuck with this Photoshop error, check the steps we listed below to resolve it.

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 System Mechanic for optimizing RAM usage.

System Mechanic comes with 2 solutions for this. One is an automated tool called RAMJet which clears RAM memory exactly when you are running low.

The other tool is called Memory Mechanic and is used to perform a deep defragmentation operation to improve responsiveness.

RAMJet is exactly what we need in this situation so that Photoshop will not complain in the future about not having enough memory.
