In other words, how do I get the most out using it?

I have run the CPU torture test a few times while overclocking (and things seem fine), and I've run the benchmark, but I don't really know what any of the results mean. I don't really understand what it's doing. For example, I have no idea what FFT length means. I sort of understand the ms times, but other than that - I run it, and it's like...OK, now what?

I've never run it to find any Mersenne Prime numbers, only to run tests.
 
Just run it as test. You're only trying to see if your oc is stable or not. Personally, I run it for at leat 8 hours, some run it for more some less. . There realy is no need to run the benchmark.

Look for the guidelines for thorough stability testing sticky, it will tell you how to use it. As, for FFT length, you first need to know what an FFT is. Mathworld explains it better than I can:

Although it helps if you already know that a Fourier transform is:

Basically, run it (the torture test) with high priority until you get an error message, it freezes or you are convinced that it is stable. Usually, peple who need absolute stability reccomend 24 hours or more.

I looked at those links you gave, and now I'm almost sorry I asked, LOL! I have nothing against trying to learn new things, but the math on those pages is way beyond what I'm capable of. :confused: Math and I never really got along that well. I almost wish you had tried to explain it...I might have understood it better, LOL! I think I'll just stick to running the tests and let the computer worry about what it all means...
 
I've played with Fourier transforms in some of my physics, but never an FFT, so I'm afraid I can't explain that to you very well.

edit: Here's some more information on how prime95 works. THe math is somewhat less hard, because it just says what they use FFTs for:
