    Why does my 6900k not clock at 4Ghz when Turbo Boost 3.0 is active?


      I've bought a 6900k processor and when I install the Turbo Boost 3.0 driver, I am only clocking at 3.7Ghz.

      Intel Ark says that the 6900k processor clocks at 4Ghz when Turbo Boost 3.0 is enabled and has a max boost of 3.7Ghz:

      Intel® Core™ i7-6900K Processor (20M Cache, up to 3.70 GHz) Specifications


      When I run 3DMark benchmarking software, I can see that my processor is running at 100%, but that it caps at 3.7Ghz.


      My motherboard is an MSI Intel X99A RGB LED GAMING PRO CARBON ATX Motherboard.


      I've looked in the BIOS and I think that I've set everything up correctly to enable Turbo Boost.



      I have installed the Turbo Boost 3.0 drivers successfully and added 3dmark (64bit) software to the apps list.

      I was also running 3dmark in the main window when benchmarking



      Anyone have any ideas?
