Windows 10: CPU cuts its frequency while is on AC

While laptop is on chargercharger itself is original 100W charger, only 3 months old and if battery percentage is below 40% than CPU cuts its frequency down to 800MHz from base frequency 3.2HGHz. This issue takes place only when there is any game launched or "turbo" power mode is activatedthis mode is supposed to boost CPU frequency and CPU & GPU fan RPM count. For understanding, normally on AC turbo mode CPU frequency is 4GHz. On other power modes and w/o any opened games CPU frequency is about 2.6GHz, what is a bit lower than on battery but still acceptable. Normally on other power m

INCORRECT CPU FREQUENCY READING

Hello Muhammad,

CPU usage depends on the applications that are open to your device. To isolate the problem, we suggest that you answer the following questions:

• Can you include a screenshot of the CPU reading?
• Have you tried performing a
  clean boot to eliminate software conflicts?
• What troubleshooting steps have you done so far?

Looking forward to your response.

 

CPU 101 -- Frequency Vs. Boost

I'd say forget about base frequency, you could force computer to run much lower anyway. It's just highest frequency CPU would run at if no boost is allowed.If boost is enabled, under appropriate load some cores will boost to higher frequency until certain step and if even more load is applied one core will boost to even higher frequency.

 

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
