Windows 10: Task Manager not showing correct CPU speed

On a fresh install of windows 10 home made with USB installation media from https://www.microsoft.com/en-us/software-download/windows10 brand new Dell Inspiron 15 3593 task manager constantly shows the base clock [1.19Ghz] regardless of power settings CPU-Z shows actual clock speed. BIOS & Windows has been fully updated and is running very close to a vanilla install.



Anyone know what to do to fix this

Task manager shows incorrect RAM speeds...

It is actually a bug occurring primarily with many AMD boards. CPU-Z and bios will report accurate speeds (CPU-Z always will report half speed and thats correct) yet the task manager which usually reports full speed is reporting only half speed also.

Its a confirmed windows bug that is caused by the smbios info not being read right. It does not impact performance or memory allocation and microsoft reccommend using another software to measure speed.

 

task manager displays wrong cpu speed/utilization



as can be seen, windows 10's task manager reports cpu speed as 3.26, where it is actually 4.13.

similarly, a multiplier of 28 will show a maximum cpu utilization of 80%.

the computer is running prime95, so it is definitely 100% loaded; this can be seen in various applications (e.g. intel extreme tuning utility, and many many others)

possibly the 125 bus speed is ignored? task manager seems to assume it is set to 100 in its calculations

is there a fix for this?

 

(Windows 10) Task Manager shows nearly doubled CPU speed values

Hi,

Provide us the below information to assist you better.

• What is the make and model of the computer?
• Have you manually changed overclocking within BIOS settings?

The “Maximum speed” that is shown on the right is the frequency the processor advertises, as reported directly from the
processor. However processors have the ability to use “turbo” states where it can temporarily run faster than its advertised maximum. Most modern processors will do this.

In addition, different algorithms are used to measure processor speed. For example, the algorithm used by Intel in its branded maximum speed is different than the algorithm used by Task Manager to directly measure the speed of
the CPU. You can use other processor utilities, such as the Intel Processor Identification Utility or CPU-Z, for additional processor speed measurements.

So what you are seeing is likely a difference in calculation method – Windows is not running the CPU over the recommended frequency (unless you are manually overclocking the CPU within the BIOS/UEFI settings).

Also this should not impact your computer in terms of power consumption or less performance.
