One core at 98%

[alexisvx]

Hi All,

I recently upgraded my CPU and mobo to an i7-9700k. 

HWM monitor shows that on idle, on the Utilization section, one of my CPU cores runs between 80% to 98% while the others are between 1% to 28%. I tried rebooting and the core that runs high keeps changing, i.e. it's not always the same core that runs so high. 

I've started the process of overclocking and thought it might be linked to that but even when resetting to stock settings the same thing is happening. My temps are fine.

Is this normal behavior or could this be a faulty processor or bios settings? 

Thanks

Check task manager to see what is using that core

Check your CPU load with processes in task manager and see what's causing the workload..  I don't think it should be running at 100% if you're not doing anything..

 

I don't know what you have running in the background but I have one core running at around ~30% at the moment with just this window open with a few background apps I keep running.. Once I start doing more things, other cores get involved and it starts distributing the workload..

Post screenshots of your task manager showing the Processes and Performance tabs.

Thanks for the replies.

I'll post screenshots of task manager tonight.

I attach 2 screenshots of task manager. 

Does this look normal?

I would say good bye to iCloud Photo Library and Dropbox too.  Why have stuff like that degrading your computer experience?  Any app that locks itself to one core is poorly programmed and should be deleted.

 

Here is how Windows 10 - 1809 looks on my old 4 core 4th Gen laptop CPU when idle.  Can you see the difference?  Every time you install an app you have to keep an eye on what it is doing to your computer.  Windows 10 is not bad at all.  I almost need a magnifying glass to see CPU Usage.

After killing iPhoto, CPU usage went to almost 0%. 

 

I find it incredible that an app from a developer such as Apple would be so poorly optimized.

Well it's not being run on an Apple device so why should they care lol?
