Hard faults per second (HFS) is a measure of the number of hard page faults that occur in a given second. A hard page fault occurs when a program requests a page of memory that is not currently in the computer’s main memory. The computer must then access the page from the hard drive, which is a much slower process than accessing memory that is already in the main memory. HFS is an important metric for measuring the performance of a computer system, as it can indicate how much time is being spent waiting for data to be retrieved from the hard drive.
To fix a high HFS, it is important to identify the cause of the issue. Common causes of high HFS include insufficient RAM, fragmented hard drive, and inefficient software. Increasing the amount of RAM can help reduce the number of hard page faults, as more memory will be available for programs to use. Defragmenting the hard drive can also help, as it will reduce the amount of time it takes to access data from the hard drive. Finally, optimizing software can help reduce the number of hard page faults, as inefficient software can cause the computer to request more data than necessary.

Hard faults per second (HFS) is a measure of the number of hard page faults that occur in a given second. A hard page fault occurs when a program requests a page of memory that is not currently in the computer’s main memory. This requires the computer to access the page from the hard drive, which is a much slower process than accessing memory that is already in main memory.
To fix hard faults per second, you should first identify the cause of the issue. Common causes include insufficient RAM, fragmented hard drive, and applications that are not optimized for the system. Once the cause is identified, you can take steps to address the issue. This may include adding more RAM, defragmenting the hard drive, or optimizing applications for the system.
With the advancement in computer systems, memory space and information within a PC have gradually increased too. Processing this memory information is a normal part of hard faults. Hard faults are not an issue of the quality or brand of memory but are an exception usually encountered during normal or irregular processing. In this guide, we will learn a lot more about memory hard faults per second, why excessive hard faults are encountered, and some methods to help fix the memory hard fault issue. If you are looking for solutions to hard faults with free memory issue, tag along and go through some of the effective fixes that will resolve Windows resource monitor hard faults.
What is Hard faults Per Second? How to Fix it
As discussed earlier, hard faults, earlier known as page faults, are a normal part of processing the memory information in a computer. It is not an issue, but rather hard faults are encountered when the operating system retrieves memory pages from the Page File (Virtual Memory) and not from the physical memory (RAM). However, as the excess of everything is bad, so is the case with hard faults. If you are experiencing a greater number of hard faults than usual, it might indicate that your computer needs more physical memory (RAM). The number of hard faults is completely based on your PC’s specifications and tasks.
What Causes Hard Faults with Free Memory?
Even though you are already familiar with the main cause of hard faults, which is low RAM in a PC, upon checking the system. Many users have reported having free memory while facing dozens of hard faults. In this case, do not be misled with available or free memory, as shown in the Task Manager of your PC. Most of this memory is not free and is already being used up, leading to a big contradiction.
Apart from memory issues, a number higher than usual (20 or under, considering the amount of RAM you have) is a problem for you. This can result from various causes that are listed below:
- Hard faults per second are encountered when the address memory of a specific program has been switched to the main paging file than the main memory slot. This causes the PC to experience a slowdown and increased hard disk activity due to its effort to find the missing memory.
- Also, the issue of high hard faults can be encountered during a hard disk thrash. In this case, the hard drive continues to run at full speed while your computer carries a disk thrash or when a program stops responding.
- In addition, hard faults can be experienced while running too many programs on a PC simultaneously.
What are Windows Resource Monitor Hard Faults?
Resource Monitor is an important PC tool that imparts information on real-time data feeds about the important systems running on your computer. The utility is extremely helpful in monitoring the health of your system and fixing issues regarding its performance. You can check the presence and allocation of multiple resources in your system with the help of the Resource Monitor. You can also check the information about the use of hardware, including memory, CPU, disk & network and software, including file handles and modules. In its Memory section, you will likely check the number of hard faults/secs representing the percentage of used physical memory. All in all, Resource Monitor is an amazingly vital utility in all versions of Windows.
How to Fix Memory Hard Faults Per Second Issue
If you are encountering a high number of hard faults (hundreds/sec) in your system, then you need to address the issue, keeping in mind the possible causes mentioned above that can trigger this situation. So, let us begin with the troubleshooting methods to fix this situation for you.
Method 1: Add More RAM
As we have already discussed, the main cause of the higher number of hard faults per second is low RAM. Therefore, to overcome the issue of hard faults, you need more RAM. As the more you have it, the fewer hard faults per second you will encounter. To do so, you can start by checking your system configuration to know if you have enough RAM in the current Windows version. If you do not meet the requirements (the 64-bit version requires double the memory than the 32-bit version), you need to buy additional RAM or add more to your computer.

Method 2: Re-enable Pagefile.sys
In case you are experiencing hard faults with free memory, this method will help you resolve the issue quite effectively. It includes disabling and then re-enabling Pagefile.sys. Your Windows PC is designed to use a paging file.
- A paging file helps in the more efficient use of physical memory by removing infrequently accessed modified pages from RAM.
- A paging file is necessary to get the most out of your RAM. You can make changes to it by adjusting its size, tweaking its configurations, and also disable it to lower the number of hard faults.
Here is how you can first disable and then re-enable Pagefile.sys:
Note: If the page file is disabled, some programs will not function properly as they are solely designed to use it.
1. Open File Explorer by pressing the Windows + E keys simultaneously.
2. Now, right-click on This PC and select Properties from the menu.
3. Click on the Advanced system settings from the side panel.
4. In the Advanced tab, click on Settings… under Performance.
5. Now in the Advanced tab, click on the Change… button.
6. Next, uncheck the box for Automatically manage paging file size for all drives.
7. Now, select the drive you want to disable Pagefile.sys and select No paging file.
8. Then, click on Set > OK to save the changes.
9. Once done, restart your PC to apply the changes made.
10. Finally, you can re-enable Pagefile.sys with the help of the steps given above.

What is Hard Faults Per Second?
Hard Faults Per Second (HFPs) is a measure of the number of hard page faults that occur in a given second. A hard page fault occurs when a program requests a page of memory that is not currently in the computer’s main memory. The computer must then access the page from the hard drive, which is a much slower process than accessing memory that is already in the main memory.
How to Fix Hard Faults Per Second
There are several ways to reduce the number of hard page faults that occur in a given second. The most effective way is to increase the amount of RAM in the computer. This will allow more memory to be stored in the main memory, reducing the need to access the hard drive.
Another way to reduce hard page faults is to optimize the programs that are running on the computer. This can be done by reducing the number of programs that are running at the same time, or by optimizing the code of the programs that are running.
Finally, it is important to keep the computer’s hard drive clean and defragmented. This will help to reduce the amount of time it takes for the computer to access the hard drive when a page fault occurs.
