Jump to solution

Hi,

what are the correct values  for PL1 and PL2 to make the most performance for my CPU?

Hi Kruis

I would recommend that you stay with the default values as this platform has been already set up to maximize product efficiency but if you still want to do your own customization please refer to the data sheet for the  "10th Gen Intel® Core™ processor families, Pentium® processors, and Celeron® processors for U, H and S processor lines that is available here: https://www.intel.com/content/www/us/en/products/docs/processors/core/core-technical-resources.html once you download the document: 615211-005.pdf refer to the section: 5.1.3.1. Package Power Control.

Keep in mind that these options are intended for system designers and to do their product-specific configuration, and this particular guide is for the processor alone, the NUC has already been designed to take the most out of the platform. 

Power Limits in NUC are specified in seconds

On the other hand,  if Intel® Turbo Boost Technology is not reaching Max Frequency ist it very possible that your workload/application is not demanding maximum processor frequency, then the processor might not reach the Turbo max frequency. 

 

I hope this helps,

Hello Kruis, 

 

Thank you for posting on the Intel® communities.   

 

So we can better assist you, please provide the full model number of your Intel® NUC. You can get this and other useful information if you run the Intel® System Support Utility (Intel® SSU) and attach the report generated:  

 

  • Open the application, check the "Everything" box, and click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".   
  • Click on the menu where it says "Summary" to change to "Detailed View".   
  • To save your scan, click on "Next", then "Save".   
  • Use the option under the reply window to attach the report to the thread (Drag and drop here or browse files to attach).  

 

Regards,

Hello Kruis,  

  

Thank you for your reply. 

 

I can see that you have an Intel® NUC10i3FNH with an Intel® Core™ i3-10110U Processor.  

 

Please visit the datasheet for this i3-10110U, under Table 4-2 Turbo Package Specifications:  

https://www.intel.com/content/www/us/en/products/docs/processors/core/10th-gen-core-families-datashe... 

 

The PL1 is 15 W and the PL2 is PL1*1.25

However, we do not provide support or instructions on how to change these values as they will be set by the system by default.

Hello Sebastian,

thank you for your reply.

 

I've read the table: PL1 = 15w, PL2 = 18,75

But I'm really confused because by default, the BIOS settings are PL1 (sustained)=30 and PL2 (Burst mode)=40 

Maybe they are different values from the PL1 and PL2 values in watts?

Moreover, using HWInfo tool I see peaks of max 3691MHz for CPU clock frequency; it never went higher than 3691MHz, but max clock frequency  should be 4.1GHz. 

Is a configuration problem?

Thank you for your patience.

 

Regards,

Cristian

Hi Ronny,

thank you too for your help!

Then, I leave all parameters as the default!

Regards,

Hello Ronny!

I know this post is a bit old but just to clear something up: you say the values are expresssed in minutes and in BIOSs comment it also states the same. But in practice I wonder if its a mistake. Namelky when I try to alter those numbers in accordance to the technical papet (15 for pl1 and 19 for pl2) in HWinfo it is reflected in Watts. So I think these values are not in seconds as it says in the bios.

Would it be wrong if values entered in this section were 15 and 19? What about the next value, TaU? In the paper it says that setting of 28 seconds is recommended. I tried that but I think my average temperatures were higher with such a setting (15, 19, 28). I tried lower value for TaU (8 seconds) and the temps were lower. This is not real testing as circumstances of system services running might have been different. 

Can you clarify a bit? 

The reason for fiddling about in BIOS is that defaults are extremely crude and NUC is going off like crazy all the time with ramping up fan speed, HWinfo showing thermal throttling flags from time to time ...

I have set fans to custom by one of the intel forum board members here and operation has been smoother. I just wondfer if cappin a little bit of performance in Power settings like mentioned above would put the functioning into more conservative (and factory specified!) frame.
