What To Do If Computer Is Not Using All RAM

RAM or Random Access Memory is one of the fundamental elements of your computer. It is your computer’s short-term memory where your computer stores all that data that it needs to access quickly. It is ideal for apps, processes, and other programs. But, what if your computer is not using all RAM as opposed to overutilized RAM? More importantly, what would happen if your PC doesn’t use all the RAM that is there, and what can be done? That’s what this post is for.

What Will Happen If Your PC Will Not Use All RAM

Let’s assume you have 8 GB worth of RAM but only 5 GBs is utilized. Normally, some RAM is reserved for certain things such as if you have an integrated graphics card or BIOS which is somewhere around 2% but, if say, you have 16 GB RAM  and you are seeing just 8 GB or less in Task Manager, then that’s a problem. Some users have even reported that they were not able to see the RAM option itself in the Task Manager.

In any case, if your PC is not using all the RAM, you would see a drop in the PC performance because your computer will be using fewer resources and you’ll have issues multitasking.

  3. Your RAM is not properly configured on your PC.
  4. Outdated BIOS
  5. You use an integrated graphics card which is consuming some part of your RAM
