Turbo boost not working for i7 2700k

Hi i have i7 2700k that is 3.5 GHz stock and 3.9 GHz turbo boost but when i try to run 3 different programs on my system or any stress test i get only 3.6 GHz of clock speed. I have reset the BIOS and tried overclocking but couldn?t go past 3.7 ghz. I have Intel dp67bg motherboard. Please help give me your suggestions on it.

Re: Turbo boost not working for i7 2700k

Intel Turbo boost allows your processor to automatically increase or decrease the clock speed as per the requirement it also adjusts the power consumption when it your system need additional boost for performing the task. Hence it is normal if your computer is working under the 3.9 GHz which is maximum turbo frequency for this processor.

I think that the Turbo boost might be disabled in the BIOS, just look for its settings properly. You can also try to use other software like CPUZ and orthos or prime95 to load the CPU to see if its start to work or not. Also, if possible then try to load only single core and check if that makes any difference, you can do the same by opening Prime95 and select only 1 thread. After that open Task Manager to the Performance tab to ensure all other cores are idle.

Re: Turbo boost not working for i7 2700k

Can you try to ensure that the C-states and C3/C6 are turned ON in the BIOS. The Intel Core i7-2700k will be able to use a maximum Turbo Boost when all this settings are turned on. You can check out the ThrottleStop for correct monitoring purpose at the thread level. With this software you will be able to adjust if disable turbo boost that is usually set in the CPU.
