I recently bench marked my system in 3dMark. While undergoing the CPU intensive part of the test, the frequency didn't go above 3395 MHz, even when i enabled turbo boost. I also suspect that this problem is causing some of my other games to stutter a bit. How could i fix this? Thank you for your time.

What is your cooling solution, and what temperatures do you have on the package and on the cores? This could be caused by thermal throtteling (i.e when the CPU forces itself to run slower due to overheating). Alternatively, it could be how Intel's Turbo Boost technology works. The CPU cores need to exceed a certain usage level before the feature kicks in (easily said), however since this happened in a synthetic benchmark test, which (i presume) pushes the CPU quite hard, it should kick in allright.

Okay. As it seems, the CPU is not using Turbo Boost at all. Have you tried to reset your BIOS options to their default values? Turbo Boost should be applied by default. You could also run the Intel Processor Diagnostic Tool to see if it finds a problem. What power supply do you use? Is there enough power going to the CPU?
Sorry for not responding. I have tried resetting to the bios defaults, no luck there. And when I ran the tests again, i realized that usage changes between 99% to 100%. I also ran the diagnostic tool, and there was no problem. I use an EVGA 650 GQ power supply. As far as i know, the CPU is getting enough power.

There certainly seems to be no issue there. Have you updated your system drivers recently? If not, do that. Perhaps you could try to update the BIOS aswell, if you have the availability to. Strange issue, this.

I see. I have one final idea of what might cause this. What power plan do you use in Windows (if you use Windows, ofcourse)? Make sure that it's not in Power Saver, or similar, as that may prevent the CPU from overclocking.

Okay. Then I have no further idea, unfortunately. I'd get in touch with Intel themselves and see what they say.
