Is it ok to change CPU rate limit of SID mid process?


One process in particular is using a lot of CPU (100% and raising temps to 95C) which needs to run for long period of time(~3 hrs). Using this guide helped limit the usable bandwidth of CPU to 50%. But unfortunately it slowed that process considerably(~9hrs), is it ok if I raised the CPU rate limit to higher number mid process.

Also the process does not allow changing affinity or priority?

Hello CS90,



Thank you for joining the Intel Community Support.



Depending on the system you have, it may have a negative impact. Please allow me to gather basic information to provide a detailed answer about the behavior your computer experiencies.



First, what is the application/process that causes high CPU usage?



Also, please scan your computer using the Intel® System Support Utility. Follow the steps below:



1.Download the Intel® System Support Utility and save the application.


2.Open the application and click Scan to see system and device information. The Intel® System Support Utility defaults to the Summary View on the output screen following the scan. Click the menu where it says summary to change to Detailed View.


3.To save your scan, click Next and click Save. You can save the file to any accessible location on your computer.


4. Attach the report to this thread.



Also, to verify the functionality of your processor, please run the Intel® Processor Diagnostic Tool and share the results. You can find the link below:
