NUC10i7FNK - Power Limit not working

[JN2]

Maybe I am doing something wrong but my NUC ignores set PL1 and PL2 limits.

I am not sure if this is BIOS bug or something additional needs to be set for PL limits to be respected.

Screenshots of HWinfo sensors tab and BIOS Power settings are attached to this post.

NUC:  NUC10i7FNK

BIOS version:  FNCML3357.0052.2021.0409.1144

Thank you

Hello JN2,  

Thank you for posting on the Intel® communities.   

In order to better assist you, please provide the following:  

1. Have you noticed overheating?

2. Have you tried with different fan modes?

3. Have you tried disabling Turbo boost?

4. Have you tried a BIOS recovery?

Hello Deivid,

   here I send requested answers:

1) Yes I have. Temperatures in load are over 90°C. Sometimes it even goes so high that NUC hard resets to prevent damage to itself.

2) Currently I am using Balanced mode. Ambient temperature in these summer days is 29°C. Since Cool mode is very noisy I wanted to reduce power limits to not have to use that mode.

3) With Turbo boost turned off max power is about 13W you can see that on picture.  Performance is noticeably lower.

4) Yes I have and that had no effect on NUC respecting power limits. So no change in NUC behavior.

Hello JN2, 

Thanks for the information provided.

I would like you to try the following:

1. Load BIOS defaults:

- Press F2 during boot to enter BIOS Setup.

- Press F9 to load defaults.

- Press F10 to save and exit BIOS Setup.

2. Clear the event log:

- Press F2 during boot to enter BIOS Setup.

- On the main screen, under the Event Log pane, check the box to Clear Event Log.

- Press F10 to save and exit BIOS Setup.

- Restart the Intel NUC.

3. Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system.  

· Download the Intel® SSU and save the application on your computer: https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-  

· Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".  

· To save your scan, click Next and click Save.

Hello Deivid,

   problem with ignoring power limits remained even after load defaults in BIOS.

Default settings are 30/60W/0s. In load power reached 72W.

I enclose requested details about the system from Intel SSU.
