Windows 10: Task manager reporting surreal CPU frequencies

I've recently purchased a computer with an i7 2700k (Sandy Bridge-DT) on a Gigabyte GA-H61M-S2PV rev 2.2 motherboard. I installed Windows 10 via the Media Creation Tool (version 1903), and from day 1 I'm getting problems with Task manager's CPU frequency readings. Other tools read proper values, it's just task manager.

Tried so far:

- reinstall

- "repair this computer" from the USB key

:)

 

Overclock cpu max frequency constantly changing in task manager

Hi,

I'm overclocking my Intel 8700k to 5Ghz and every time I check the current frequency in task manager the max is constantly changing. I have high-performance power settings on windows enabled and I have also disabled CPU state and Intel SpeedStep in the BIOS.
I also noticed that when using other tools to display my GPU and CPU performance they show my CPU max frequency is exactly 5Ghz, why does Task Manager constantly display a constantly changing frequency?

Any suggestions?

Much appreciated

 

Task Manager reporting extreme fluctuating CPU Frequencies

TL;DR CPU being displayed between 4.4 and 6.8 GHz

Task Manager is showing my CPU frequency as 3.20 in the headline under the Performance tab:

Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz

Which is the default speed of the CPU. So far so good.

But the realtime display varies between 4.40 GHz to 6.83 GHz.

HWinfo says it is 4.6 GHz which is what I have it OC'ed at.

My processor would fry if were at 6.8 GHz

PC works fine but would be nice if Task Manager also worked correctly

Overclock cpu max frequency constantly changing in task manager

Hi,

Thank you for writing to Microsoft Community Forums.

I appreciate the time and efforts to work on the issue.

As per the description, I understand that Task manager displays constant change in CPU frequency. As you have already disabled Intel Speed Step, I suggest you to get in touch with the motherboard manufacturer.

You can also post your query in the
TechNet forum.

Hope it helps.
