Bleifuss: Thank you very much for joining the Intel® Processors communities. We will do our best in order to help you.

In regard to your inquiry, remember that the feature speed step that is located in the BIOS needs to be enable for the Intel® Turbo Boost Max Technology to work. We can run the Intel® Processors Diagnostics Tool in order to confirm if the processor is working fine:https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool Also, the Intel® Turbo Boost Max Technology 3.0 works automatically depending on the load of work. Are you using a stress tool on the processor to activate the Intel® Turbo Boost Max Technology?Where are you seeing that the clock speed does not go up higher than 3.6GHz? Any further questions, please let me know. Regards,Alberto R

Remember too that Turbo is dependent upon temperatures as well. If the processor is running at a high temperature, iris not going to be able to use Turbo.

Sorry. I forgot this. I am using benchmarks to give the processor load.

I send you the test resuts with a personal message. I see my clock speeds in the Windows Taks Manager and also in CPU-Z. My temperatures should be also right.

Quick Update. I can not send you the result via a personal message. So I send you a picture down below.

Bleifuss: Thank you very much for that information and the picture. Did you found the speed step option on the BIOS? Is it enable?

Any questions, please let me know. Regards,Alberto R

Yes, it was activated before.

Bleifuss: Thank you very much for sharing the picture. In this case pretty much you tried all the troubleshoot steps we recommend for this scenario, the next thing to do if you have the option of course will be to swap parts, meaning to test your processor on a different board or test your board with a different processor.

If that option is not available, then we can always replace the processor for you, please get in contact directly with Intel if you are interested in replacing it:Chat support:http://intelsupportchat.force.com/icslivechat/ics_tech_processor_ww_english_Chat http://intelsupportchat.force.com/icslivechat/ics_tech_processor_ww_english_Chat, For phone support, depending on your location, you will see the contact information on the links below: EMEA contact information: http://intel.ly/28QeAF3 http://intel.ly/28QeAF3APAC contact information: http://intel.ly/1ITfjUF http://intel.ly/1ITfjUFLAR contact information: http://intel.ly/29c0rW4 http://intel.ly/29c0rW4North America: Phone Number 1-916-377-7000, Monday - Friday 7:00 AM to 5:00 PM (Pacific Time).

Hello Alberto,

Thank you verry mutch for this offer. But I found the solution it is a bug from Windows. Windows does not showen the correct clock speed in the Task Manager.

I found a CPU-Z Version Special for this Mainboard or from MSI.

Here you can see that Turbo Boost is working but I don't now why Windows do not show this.

Thank you for you Help.

I will mark this as my solution. Now it my part to find the problem in Windows.
