In windows 7, what is a memory "hard fault"?

The Windows 7 resource monitor displays a window labeled "Memory 100 Hard Faults/sec."  I occaisionally see non-zero spikes.  Does this mean I have defective RAM?

Hard faults do not represent an error condition. They are a normal part of memory processing.

When a hard fault occurs, it simply means that the block of memory had to be retrieved from the Page File (Virtual Memory) instead of the physical memory (RAM).

An excessive number of hard faults could indicate a need to increase the physical memory.

Please see the following article for a complete description of the different terms used for Memory management.
