Built my first computer a few weeks ago and it has been running fine. I have finally gotten around to doing some stability testing. I haven't overclocked the computer yet. I turned on Prime 95 and started a small FFT torture test last night at about 10pm. When I came down this morning I noticed that there are gaps in the worker list of like four hours. Looks like this:

[Mar 10 03:30] Test 13, 380000 Lucas-Lehmer iterations of M282625 using FFT length 16K.
[Mar 10 07:30] Self-test 16K passed!

or

[Mar 9 21:56] Test 2, 460000 Lucas-Lehmer iterations of M245759 using FFT length 12K.
[Mar 9 21:57] Test 3, 460000 Lucas-Lehmer iterations of M245281 using FFT length 12K.
[Mar 10 03:00] Self-test 12K passed!

What is going on in those mystery hours? Is the thing actually turned off? When I stopped the program it said the torture test ran for 10 hours and 40 minutes, so I'm guessing not.

My hunch is that everything is fine, and I guess part of the issue is, I really have no idea what I'm looking at in these worker sheets. Lucas-Lehmer iterations?! Sounds very mathy though, doesn't it?

not entirely sure what is happening there, but all-in-all, you're main concern is that there are no errors, no errors = goodness :)

The small fft's test, because it runs from the CPU cache, checks CPU overclocks. The large fft's and blend tests the memory.

I run the blend test 6 to 8 hours and the small fft's test for 24 hours.
