Solved Hard Faults - explain

[stu2000]

Dear all,
I noticed that I was getting tens and sometimes hundreds of hard faults, and I read somewhere that it is an error when reading the pagefile (memory on the hard drive). I figure I have 8 gigs of ram (64 bit) and my system is never going past 2.5, so I disable the pagefile and restart.

I am now getting sometimes thousands of hard faults. I get the feeling what I read about hard faults was completely wrong. How can it be to do with the pagefile if I have no pagefile now?

Perhaps I have bad ram? This is a brand new laptop.

Many programs aquire memory workspace using the paging mechanism. But as long as there is real RAM available, that is immediately mapped to RAM addresses. So what you are seeing are false page faults. There is nothing to worry about.

Contrary to what the name 'page fault' might suggest, page faults are not errors and are common and necessary to increase the amount of memory available to programs in any operating system that utilizes virtual memory...

But it should be noted that in a case like the OP's (8GB of RAM), an "increase of the amount of memory" is practically never required and the addresses are all mapped to real memory.
