OCing guide Prime95 help


Recommended Posts

I'm using the OCing guide in this forum. I’m doing pretty well but when I get to the part were I'm supposed to Prime when finding my max MHZ of my Proc with the Prime95 torture test. However when I select it I have four options.

 

1: Small FFTs (maximum FPU stress, data fits in L2 cache, RAM not tested much)

2: In-place large FFTs (maximum heat, power consumption, some RAM tested)

3: Blend (tests some of everything, lots of RAM tested)

4: Custom Min/Max FFT size (in K), Run FFTs in-place, Memory to use (in MB) and Time to run each FFT size (in minutes)

 

I don’t know which one I'm supposed to use?

I've found that SmallFFTs' tend to irritate the CPU most and Large FFT's really give memory a workout. The blend is what I use to test everyting for long periods. You'll note the cPU temp goes up a little more when you run Small FFTs'. Custom alows you to assign amount of memory to the test so if you have 2 Gig, you can assign larger quantity of mem to the test.
