Whenever this happens, your system will suffer certain slowdowns and increased hard disk activity. This forces the system to go looking for the missing memory on the hard disk instead of fetching it from the physical memory (RAM). However, hard faults (formerly known as page faults) should not be confused with soft page faults – soft page faults happen when a referenced memory page has been moved from one place in memory to another.Ī hard fault happens when the address memory of a certain program is no longer in the main memory slot but has been instead swapped out to the main paging file. Just know that they are all referring to the same thing. A lot of web resources are still referring to them as Page Faults – hence the big confusion.

Researching about hard faults can turn out to be quite tricky since they were called Page Faults in earlier Windows versions. This article was written as an informative piece, detailing the technicalities behind a hard fault as well as some tactics related to memory management. Users usually get alarmed about hard faults after landing inside the Memory tab of the Windows Resource Monitor. Depending on the PC’s specifications and the task at hand, this graph might show dozens, maybe hundreds of hard fault per seconds. However, an excessive number of hard faults is usually a good indicator that the machine in question needs more physical memory (RAM). Because of this, hard faults should not be looked upon as error conditions. A hard fault occurs when a memory block had to be retrieved from the Page File (Virtual Memory) instead of the physical memory (RAM). Hard faults are a normal part of how modern computers are currently processing memory information.
