Warrior Legolas Posted January 5, 2006 Posted January 5, 2006 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?

applejuice Posted January 5, 2006 Posted January 5, 2006 It's a matter of some debate, I think. I use Blend. Share this post Link to post Share on other sites More sharing options...
Warrior Legolas Posted January 5, 2006 Posted January 5, 2006 So basically Small FFT stresses CPU>>Motherboard/RAM Large FFT stresses CPU>Motherboard/RAM Blend stresses CPU=Motherboard/RAM Is this correct? Share this post Link to post Share on other sites More sharing options...
MacUser Posted January 30, 2006 Posted January 30, 2006 Yeah, I also would like to know which is better for testing CPU stability, Large FFT or Blend. I already know my RAM is stable cause of memtest86+, is blend a bit easier on the CPU or just harder on the RAM? Share this post Link to post Share on other sites More sharing options...
EdLSmith Posted January 30, 2006 Posted January 30, 2006 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.
