Must run with the IBT thread count set equal to the physical core count of the CPU.
HT slows it down and reduces the ability to determine stability. Set to 4 threads on a 2600K.
Set memory to "All".
Stability Criterion: Must pass 5 cycles minimum, passing 20 cycles is preferred (considered gold standard)

Like others have said, sticky please!
About the Prime95 Large FFT, I've gotten crashes on my Phenom II on Blend that I haven't gotten on Large FFT. This required me to run it 24 hours with crashes happening on the 20th hour a lot of times. These crashes were fixed by increasing increasing CPU or CPU-NB volts or downing the CPU or CPU-NB clock speeds.
