NUC10i7FNH never reaches its specified frequency of 4.7 GHz.

Hi,

 

I have recently put an intel NUC10i7FNH into operation. Unfortunately it never reaches the specified maximum frequency of 4.7 GHz. 

https://ark.intel.com/content/www/us/en/ark/products/188811/intel-nuc-10-performance-kit-nuc10i7fnh....

 

The frequency is only between 500MHz and 3.900MHz.

 

What do I have to set in the BIOS to use the high turbo levels ?

AHack4, Thank you for posting in the Intel® Communities Support.

 

In reference to your question, there is nothing to change in the BIOS for the Intel® NUC10i7FNH to reach the max Intel® Turbo Boost frequency, make sure that it has the latest BIOS installed 0037 and the settings to default value by pressing F9:

The feature of Intel® Turbo Boost Technology works automatically, it gets activated depending on the workload the Intel® NUC is processing at that moment, if it needs it the unit will activate the feature by itself, It depends as well of some factors like temperature and active cores:

We can always try to run the Intel® Extreme Tuning Utility, then run the stress test and see if it reaches 4.7 GHz, please let us know the results:

The issue also exists on Windows.

 

All the reviews I found so far reported clockrates of 3.5GHz under load for a few seconds. After that the NUC clocks down to 2.6GHz.

From that point of view I can be quite happy with my 3.9GHz for a few seconds and 3.5 for the loinger term.

 

But this is still far away from 4.7GHz.

 

 

Can You please run a NUC10i7FNH and send me a screenshot of a tool like HWInfo64 or CPU-Z to proof me, that the 4.7GHz are somehow reachable. For now I do not think, that this is possible.

AHack4, Thank you very much for letting us know that information.

 

We will do further research on this matter, as soon as I get any updates I will post all the details on this thread.

We found a solution for this. The default cp frequency governo r of a plain ubuntu installation is "powersave". This setting is responsible for the low clock rates.

 

After setting it to "performance" the cpu clocks up to 4.7GHz. The command to do this is:

for i in /sys/devices/system/cpu/cpu?/cpufreq/scaling_governor ; do echo performance | sudo tee ${i} &> /dev/null ; done

There is still some fine tuning necessary. But it clearly unleashes the power of this small computer..

 

 

So the ticket can be closed. 🙂

Hi AHack4,

 

Thanks for sharing your comments, when I read this I immediately thought about "cpupower" but for some reason, I focussed in looking for a Windows solution which I wasn't really able to find. HWinfo64 is the closest I got, so I am going to take this up and perhaps we come out with at least some documentation.

 

Thanks again for your feedback.

 

Regards,

Ronny G
