How to Fix Out of Memory Error on PC

For most modern PCs today, 8 GB of RAM is the standard, 16 GB if we talk about a gaming or work PC; however, not everyone has or can afford a modern PC, and there are times when the RAM memory is insufficient and so the operating system tells us with the error “Insufficient memory to execute the operation”. In this article we are going to tell you what you can do about it, in addition to the obvious solution which is to buy more RAM.

In terms of buying more RAM, you also have to bear in mind that if you have a relatively old PC it can be a complicated task, since nowadays stores only have DDR4 RAM in stock and it is extremely difficult to find RAM DDR3 for sale, let’s not talk about DDR2, which is the type of RAM used by old PCs. In any case, you may simply not want to spend money to expand your computer’s RAM, but if you receive an Out of Memory error, you want to know if there is anything to do before checking out.

Fix Out of Memory Error on PC

Out of memory, why do I get this error?

When the operating system gives you the Out of Memory error, the meaning is quite literal: your PC does not have enough memory to execute what you were doing and therefore it is impossible for it to do so. As you well know, RAM is a very valuable resource in any PC and unfortunately it is quite limited, although as we have told you before, today it is usually more than enough to have 8 GB for most things, or 16 GB If you already intend to use the PC for heavier tasks or for gaming.

Capacidad memoria RAM

The management of RAM memory in Windows 10 is quite good, and although you see that with the PC just started you have hardly any RAM available, this is because the operating system pre-allocates memory resources to the programs that you use most frequently in order to accelerate their load. to allocate memory resources to its internal management. In the event that more memory is needed to run other programs, Windows will reallocate this pre-allocated memory to make room for new tasks, but still, the physical capacity of your RAM may literally be insufficient.

Anyway, do not despair, because if Microsoft itself says that the minimum amount of RAM required to run Windows 10 is 2 GB for 64-bit systems, it is capable of operating with that memory capacity … as long as they are managed good resources. So let’s see what we as users can do about it.

Is the RAM in good condition?

It never hurts to start by checking if the RAM memory is in good condition and properly configured, since it is possible that there is a portion of it unusable because it is damaged. It is rare, but it can happen, so we are going to check it in the easiest way possible, which is with the tool that incorporates the operating system itself. To do this, click on the Start button and type “Windows memory diagnostic” (without the quotes) to start the tool.

Windows diagnóstico RAM

A window will appear that will give you two options (besides canceling, of course):

  • Restart now and check if there are problems (recommended) that what it will do is restart the system and start the memory checker. If it finds a problem, it will let you know, so that you can act accordingly (for example this tool will tell you if there are unrecoverable errors in the memory, in which case you would have no choice but to replace it with another because it will be damaged). .
  • Check for problems the next time the computer starts. With this option you will be able to continue using the computer normally, but the next time you turn it off and on or restart it, this memory checking tool will start.

Adjust system settings to consume less RAM

Windows 10, and especially its latest versions, is designed for relatively modern PCs that are overloaded with hardware resources and, therefore, the consumption of RAM memory can be increased. Fortunately, it is very easy to reduce the use of Windows RAM if you have insufficient memory, so for this you must click the Start button and type “Control Panel” to access the old Windows control panel. Then, in the Control Panel click on “System”.


In the window that opens, you must click on “Advanced system settings” located on the left side.

Configuración avanzada del sistema

A new window will open, in which you must access the Advanced Options tab and, in the Performance section, click on the “Settings …” button.

Configuración de rendimiento

A new window will open in which you can adjust the visual effects; By default “Let Windows choose the most appropriate configuration for the computer” is selected, but if you are having the Insufficient Memory error it is clear that it is not the most suitable, so you can always select the last option and change it or directly mark the “Adjust for best performance” option.

Opciones de rendimiento

This will make Windows look a bit “uglier” visually speaking, but it will improve your performance and your RAM consumption will go down, so it is ideal if you are getting the Out of Memory error.

Insufficient memory? Use virtual memory

Finally, the best solution for PCs with little physical RAM is to use virtual memory. This will reserve a portion of your storage device as if it were RAM; It is not ideal because its performance is much lower, but at least you will not have the problem of insufficient memory and it will allow you to run the programs that you could not before.

To activate it, you have to go back to Control Panel -> System -> Advanced system settings -> Advanced options -> Performance -> Settings, but instead of configuring the Visual Effects tab, you must go to Advanced options again where you will see At the bottom you have the Virtual Memory option.

Memoria virtual insuficiente

Click on the Change button, and check that you had it activated. In the next window you can manually assign which portion of the hard disk you want to use as virtual memory, or if you want Windows to manage it automatically. This is, however, highly recommended on computers that have less than 8GB of RAM.
