how to downclock/downvolt intel NUC 10

[ARina1]

I have a NUC 10 i7-FNH2.

I want do downclock/downvolt it to lower power consumption. 

Which bios parameter(s) have I to set?

I attach two screenshots of the bios pages I think are related to my question.

Moreover, what's the meaning of the values 30 and 64 in the second screenshot? 

Thank you.

First, you do not have an unlocked processor.

Second, you do not want to do that for security reasons:

So i cannot undervolt. Can I underclock changing the speed/multiplier?

Hello ARina1,

Thank you for posting on the Intel® communities.  

I need to inform you that as AlHill indicates, your NUC does not include an unlocked processor.

Therefore, due to the design of the device, any underclocking or overclocking is not supported for this specific model.

If may I ask, are you experiencing any issue related to frequencies or temperatures with your NUC?

If so please run the following tool and attach the reports generated.   

Intel® System Support Utility (Intel® SSU) Download link 

1.       Open the application and click on "Scan" to see the system and device information. 

2.     By default, Intel® SSU will take you to the "Summary View".   

3.       Click on the menu where it says "Summary" to change to "Detailed View".
