Ok, that is very helpful. But why such a short duration? Does this stress the thermal/power load much higher than blend or in-place large FFTs?

I don't think I have enough cooling to bump the power up to 1.37V @ 4700. Or at least I don't feel comfortable pushing the thermals up that high. As it is I'm currently hitting 67C, which is already a bit higher than I wanted.

I just ran with this for the past hour, using min=1344, max =1792, mem=5500, with 2 minutes for each FFT, and it ran without errors or warnings. However, Prime95 only used 1536k and 1792k FFTs throughout the test, so I'm not sure if min=1344 should be changed to get some more FFT sizes into the test. Also, RAM usage was 84% with this test, so not quite 90%.

RealTemp reports peak thermal at 66C, while the Asus AI Suite only saw 62C peak thermal. The only diff between this run and the 6+ hour run yesterday was the DDR voltage, which I raised to 1.5625V for this run.

This looks pretty good so far, and even at 6 hours stable under the previous torture test I'm pretty sure is adequate for typical workloads. I don't expect that anything I could throw at it would never push it that hard.

I thought that the picture was self explanatory (you run min and max FFT's@1344 for 25MIN as one test and 1792 min/fax for 25MIN as a second test)
you can increase the amount of your RAM ,this was just example ,with my browser open and all the tabs i use i have around 300 MB left when i run this test
The only reason i still have AI Suite II is voltage monitoring and Fan Expert ,the temperature it's showing and the alarms that go with it are simply a joke (very buggy )
Here is how you disable AI S II

and that's why you should use Turbo Ratio:Turbo Ratio:“By Per Core”

Hi,
Further to what was mentioned above, depending on your processor you may need to run more workers? My i7 2600K needs 8.

Not sure if this has been mentioned, but after looking at the picture on the first page I see PhilC said his cpu was only at 1.17v, but cpuz showed 1.27v....Phil you have wrong LLC level used. Your cpu is using more voltage than what you set in bios, it should never be more in windows that what you set in bios. Try increasing the LLC level.

I think that's because of his offset. Mine does the same exact thing. In bios it's set to 1.345 but in hw monitor it shows 1.360 min / 1.380 max. With an average vcore stead of of 1.370.

Then you need to lower your offset value. Cpu vcore in windows should never be above what you set in bios. It defeats the purpose of vdroop.

Yes, I understood. I was trying to have Prime95 alternate between FFTs instead of running with just one FFT for and entire run, then stopping, change setting and start another run. Since you can specify how long you want it to run with each FFT it's just simpler to say min of 1344, max of 1792 and use 25mins per FFT. The odd thing is it only alternated between 1596 and 1792 for some reason, it never picked a FFT smaller than 1596k.

Also understood. I was aiming for about 70%, i.e. 5500 out of 8000MB is roughly 68%, and trying to avoid the Windows swapping out memory, which usually occurs when Windows available memory drops below 20%. However, used memory came out to 84%, so when I run it again I'll probably drop this down a bit to stay right around 80% memory usage.

Thanks for link. I'm not too concerned about AI suite, I'm really only using it for voltage and fans also. But it let's me store my voltage profiles, which is cool so I can remember what I have tested or what I want to test next.
