    [8600K] High cpu usage and framerate issues

    ReasonFlees

      I recently built myself a new rig with the specs listed below using the same drives to save myself the file transfers. Since upgrading my hardware, I've run into consistent issues with high CPU usage in the range of 25-30% resting, 45-50% simply watching a live stream on Twitch, and 75-90% playing Overwatch (while other games, such as Assassin's Creed: Syndicate max the CPU right from the menu).  In addition, what I assume is an affect of the high usage, my frame rate in games is anything but stable ranging from 130 at best doing nothing down to 60-70 at times.  Moving the camera from side to side, alone, drops the FPS by 30-40.  I have tried to manually install all the drivers for the motherboard and processor that I could find and, having moved from an AMD processor, attempted to uninstall the AMD drivers that I could find.

       

      What could the issue be and how might I fix it?

       

       

      Build Specs:

      i5 8600k

      ASUS ROG Strix Z370-E

      GTX 1070 TI

      16GB G.SKILL Trident Z RGB 3000Mhz DDR4

          Thank you very much for contacting the Intel® Processor communities. We will do our best to try to assist you with this matter.
           
          In order to try to fix this problem we recommend to restore the BIOS values to defaults. Also, I can see here that the memory RAM installed is capable of running at 3000MHz and the processor supports up to 2666MHz, please make sure it is running at that speed:

          Remember that when using a video card the graphics controller of the processor gets disable and the video card takes care of all the graphics processes involved on the PC, so the graphics drivers that you need are actually provided by Nvidia:
          http://www.nvidia.com/download/driverResults.aspx/127265/en-us
           
          A BIOS update to the late version will be a good thing to try as well, version 5430 or 0428:

          Which Windows version are you using?
           
          Any further questions, please let me know.

            I am running Win 10.  I have now updated my BIOS to 0428 and set everything to default and up to date GPU drivers, however in testing after that I still have the same occurrences of high CPU and massive frame drops in games.

              Thank you for providing that information.

              Did you check if the memory RAM was running at 2666MHz?
              Do you have the option to use the PC without the video card?
              Do you have the option to swap parts, either to test the processor on a different board or test your board with a different processor?

              Please run the Intel® PDT, it does an overall test on the processor and if it passed the test then it should be fine:

                I did run the PDT previous to posting here and it came back with no issues.

                I had the RAM running at 2133MHz as was the default in the BIOS, but have changed it to 2666MHz with no change in performance

                I do have the option to run the PC without the video card with the DVI and HDMI ports on the motherboard.

                I don't, however, have the ability to test the board or processor with anything else.

                 

                Another interesting thing I've noticed, viewing cpu usage through a 3rd party program, such as MSI Afterburner or SpeedFan, shows a different percentage than Task Manager. At rest the difference averages about 10% lower and while in game it can be up to 20% lower than what Task Manager tells me.  Also neither CPU temps or GPU temps are go high while under load.

                  Thank you very much for providing those results. The fact that the processor passed the Intel® PDT test is a good indication, it should be working fine since the tool is very reliable, when you use third party tools they might have misreadings. If you could please test the PC without the video card it will let us know if the problem is related to that component. Another option to try if you have more than one memory stick, is to test it with just one of them to confirm if the problem is the same and then add the other one to check if it makes any difference.
                   
                  Any questions, please let me know.

                    Running the PC without the video card showed no real difference (possibly a slight increase) in CPU usage during tasks such as watching a live stream. Naturally I couldn't test usage or performance of any kind in a game.  When testing out the memory sticks, using only one, swapping the ones being used, and using different slots show no difference.

                     

                    Another thing I noticed while having Task Manager up all the time was the prevalence of WMI Provider Host (which could simply be because I didn't look at Task Manager a lot while using my old computer) and Antimalware Service Executable which I see using a lot of CPU usage while opening programs.  Using Overwatch as an example again, Antimalware Service Executable will start using 20% or more during boot up and a bit during shut down as well.

                     

                    Edit: Is it possible, somehow, that it's attempting to process graphical information through the CPU in addition to graphics card?  I know it should turn off the on board graphical components when it detects a card, but is there a chance it wouldn't for some odd reason?

                      Yes, it is certainly possible. First of all, most BIOSs support a configuration option that keeps the embedded graphics alive even if an external card is identified (this is often used in laptops and is referred to as hybrid graphics). Secondly, if software is unaware of the graphics card's ability to do some specific type of operation or is configured to do this type of operation in software regardless, then you may see situations where it is done in software instead of in the graphics solution.

                       

                      Hope this helps,

                        I went into the BIOS and attempted to force it to use PCIE connected graphics and ignore the CPU graphics with no difference.  Having now tested pretty much every main component of the computer to no avail, it appears that the final piece that I'm not able to test directly, the motherboard, is possibly to blame for these issues in CPU usage and frame rate instability.  Are there other things I should test for or should I start looking to replace this motherboard with a new one and possibly a different model?

                          Well, that is one possible interpretation. When I first read the report, my gut said memory issue.

                           

                          Just saying,

                            In my attempts to try everything and anything to fix my issues, I installed some clean drives I have for a computer I'm selling.  With those everything runs perfectly.  There must be some program that is causing issues with my new rig that didn't cause issues with my old AMD rig.  Very frustrating since one of the first things I did was look for programs, but the search for the program at fault begins again...
