    Unexpected high CPU frequency in 'Idle' (NUC6i5SYH)

    newnucer

      The CPU frequency in 'Idle' is around 1.8G ~ 2.7G, CPU temperature may reach to 64 degrees (Celsius), there is no any background

      active processes except for win10 system's. Is that normal?

       

      I changed the 'performance profile' in BIOS from 'high performance' to 'low power', looks like it didn't have any impact.

       

      ================================================================================================

      Kit      : NUC6i5SYH

      BIOS  : 036

      OS     : Windows 10 Pro.

      Mem   : Samsung DDR4-2133, 16GB

      SSD   : Samsung PM871 256G (Primary, SATA, win10 installed on it)

                  Sandisk X400 512G  (Secondary, M.2)

          I found that the default in the BIOS is performance and the default in Windows Power Options is performance - with these settings the CPU looked to be constantly running at clock speed of 2.8, but actually CPU usage percent was very small. I found that running with these default settings meant that the power and temperature of the NUC was higher at around 9w and 60 degrees.

          The performance power option in windows sets Graphics = Maximum Performance, CPU min = 100% and CPU max = 100% - I suspect that the performance option in the BIOS means that the CPU runs in turbo mode all the time so 2.8 instead of 1.9

           

          I created a power profile in windows with Graphics = Maximum Battery Life, CPU min = 99% and CPU max = 99% and this leaves the CPU running at it's stock clock of 1.9 and this reduced the power to 5w and temperature of 40 degrees. So I run in this mode most of the time and have a shortcut for games mode which switches the power profile to performance when I need it.

           

          I also have a night mode that sets Graphics = Maximum Battery Life, CPU min = 1% and CPU max = 1% - this leaves the CPU at a clock speed of 0.4 and this reduces the power to 1w and 30 degrees. These profiles are scheduled in windows task scheduler so 00:01 is night mode and 06:00 is normal mode - performance mode is a manual desktop shortcut and the scheduled change will auto reverse it. I run it like this as I don't want to sleep the NUC and would rather run it 24/7 but in low power.

           

          My NUC is mounted on the back of the telly and is basically an HTPC running Windows 10 and Kodi with the occasional Steam Game (CSGO/Portal2). I found that even in night mode Kodi runs fine and watching live or recorded TV is without glitch.

            Hi,

             

            My NUC (6i5 - 16GB - Win10 pro, performance profile set at performance) normally runs sub-GHZ speeds (~.70 GHZ typically) when idle. However, every now and then (think once every two days) a process called 'System and compressed memory' starts to use at least 50% CPU and CPU speed increases to the max. This process compresses memory when RAM gets low. In my case there is 16GB of ram installed of which 2-3GB is used when this occurs, so there seems to be no valid reason for this process to use CPU as it does.

             

            Rebooting the NUC always solves the problem. I think this might be a Win10 bug that will be corrected somewhere along the line.

             

             

            Kind regards,

             

            Paul

                Thanks fryrpc, I'm trying to add a few power profiles of mine to bypass the issue.

                      The CPU passed all tests, what shall I next?

                              Thank you for the report.

                               

                              I could not find anything alarming with report, but I did noticed that you have previous BIOS version, and in that case I would recommend upting it to the latest version Download BIOS Update [SYSKLi35.86A], so please give it a try.

                                I created an account so I could share my experiences with you on this matter.

                                 

                                I too have seen the constant CPU use (1 CPU thread equal to 25% CPU). Task manager shows it to be used by the 'System and compressed memory' process. This process can be broken down to each software thread, which reveals that it is the 'ACPI.sys' driver which is actually using the CPU.

                                 

                                After a reboot the system is fine with normal CPU use, but I later realized that the constant CPU use was being triggered by using the SDcard slot. My NUC is always on and is fine, days, weeks with no problems. But if I use the SDcard, constant CPU.

                                 

                                I am running the February 23rd Bios. I did not realize there was more updates. I will test the latest release in the next day or two and I will respond again with my results.

                                 

                                Regards,

                                  hmmm, also the same storry at w10?

                                  At w7 we have also problems with SD-Card NUC6I5SYH - NTFS (micro)SD

                                  I hope for you, update to 0042 will fix it at w10...
