But Here is what I ran on P95:
1. Prime 95 v27.9 Build 1
2. MAX FFT Size (in K) 1792
3. Memory to use 8192mb
4. Titme to run each FFT Size 5 minutes..
I made a mistake the Program I am using is X264 v5.01 the Video Encoder Program NOT Aida 64..
#2 is the problem. You can't just run the 1792K FFT, or limit Prime95 to the 1792K FFT instead of the default of 4096. It's far better to run the default Blend test, or better yet, the Custom Blend test (select Custom while Blend is selected). Then, just enter about 80-85% of your installed memory instead of 50%. That would be precisely 13107 - 19275 MB. Or, 13000 - 19000 if you want to round it just for the heck of it. If you want to use 85% or higher, then, I recommend doing so on a fresh boot with the "Windows Classic" theme selected
before rebooting and only 1 solid color wallpaper (no Desktop Slide Show) and with the least amount of programs running at startup (so, all unnecessary programs disabled or told to not start with Windows, or deleted from the Startup start menu folder, etc. etc. etc.). I would recommend doing this anyway because it's a superior way to do it, but it becomes especially important the more and more memory you tell Prime95 to use, especially above about 85%.
It's best to leave the setting alone that says "Time to run each FFT size" because 15 minutes is far better than just 5. There's no real good need to shorten this time. I mean, there really aren't any valid shortcuts in stress testing.
So, the goal is to try to get your system so stable that it can run this test for 24 hours. Why 24? Because there are 82 FFTs in total and it takes about 24 hours to get through all of them. I know, 82 x 15 is 1,230 minutes which is 20.5 hours, but you will notice that it takes longer than 15 minutes to do each FFT size and it adds up to being roughly 24 hours to get through all 82 of them one time each. I don't know why, but that's just the way it is.
So, some people reading this might ask me, "well, why the Blend test? Look at what it says about the Large FFTs or the Small FFTs" The answer is, for these CPUs like Sandy Bridge, Ivy Bridge, etc., we need something that will stress both the IMC and the CPU cores at the same time (the IMC is the Integrated Memory Controller). So, reader, if you have an older generation CPU like say a Core2, then use the Small FFTs test because that CPU generation doesn't have an IMC and therefore the Blend test is less stressful for your CPU. I'm not 100% sure, but I
think that the first generation Core i Series has an IMC (that would be CPUs like the i7-920 and other 3-digit i3/i5/i7 models like it), but don't quote me on that. Ok?
Anyway The_Nephilim, let me know how this goes!
