10 Fixes for Windows Hardware Reserved Memory

Is your computer running slowly because your memory is being reserved more and more? Let’s see why this happens and how we can reduce the number of hardware reserved memory windows.

What is hardware reserved memory?

Hardware-reserved memory is a separate section of memory dedicated to critical computer functions. These processes provide coordination between the CPU and external peripherals such as graphics, keyboard, printer, etc. They are not available for normal day to day processes.

Everyone wants their device to work like a horse. A big chunk of system performance is RAM. It provides temporary storage space for various applications.

For example, if you start playing Fortnite, your saved maps will be copied from storage to RAM. Then you start completing missions and your RAM runs at lightning speed for fast-paced gameplay. Later, the files are moved back to the storage drive.

So where does hardware reserved memory fit into this picture? Well, it works in the background, ensuring that the various parts of the computer work in harmony during this saga.

How is free RAM related to system speed?

RAM alone can determine the efficiency of a system. There are two factors of RAM that affect system speed.

• Memory Capacity: The amount of memory that can be stored in RAM. Measured in gigabytes.
• Memory speed: This is the speed at which the RAM can process various programs.

As a rule, increasing the amount of memory has an exponential effect on system performance. This means that RAM stores more data and processes information faster.

How is hardware reserved memory used?

Image and video processing requires breakneck speed. RAM works like a breeze, so the hardware reserved memory is mostly part of the virtual RAM used to optimize graphics performance.

In addition, hardware reserved memory is also used to store drivers for computer peripherals such as monitors, keyboards, mice, and trackpads, provided with dedicated storage to ensure that their operation is never interrupted.

What are the causes of high hardware headroom?

An increase in hardware headroom can occur for various reasons. It mostly happens when your graphics card is outdated or designed to use some of the RAM for processing. Bugs in the BIOS can also increase the hardware reserved memory.

Warning

When you see that the hardware reserved memory has increased to the value of the entire RAM module, it means that the RAM is corrupted.

RAM is an integral part of a computer, so get a new RAM module immediately!

How to check hardware reserved memory?

To check how much memory is reserved by hardware, do the following:

• Open Task Manager by pressing Ctrl+Shift+Esc.
• Click on the “Performance”tab.
• Finally, click Disk.
• Now look for the “Hardware Reserved”option in the lower right corner of the Task Manager.

How much hardware reserved memory is right for your PC?

A typical value for hardware reserved memory is a couple of hundred megabytes. For 32-bit systems, a maximum of 3.5 GB can be used. For 64-bit systems, out of 16 GB of RAM, 1 GB of RAM is usually reserved. Hardware reserved memory between 1 GB and 4 GB is defective and needs to be repaired.

How is RAM divided into different sections?

The division of labor ensures higher productivity and efficiency of any system. Similarly, different components of RAM are specialized for specific tasks. Here is a table showing the various components of RAM and their associated functions:

How is cached memory different from hardware reserved memory?

The cache stores information about previous processes, so the next processes are much faster. The cache interacts with the CPU and is ultimately processed faster. On the other hand, hardware reserved memory from another world, working to provide the basic functionality of the system.

Is it safe to reduce hardware reserved memory?

In most cases, it is relatively safe to reduce the hardware reserved memory. Mostly, it does not adversely affect your computer. However, in some cases, this may interfere with the download procedure.
