Windows 10: Task manager showing incorrect CPU clock and memory stats

Hayo

A while ago I was running an overclocking configuration on AMD Ryzen Master which, besides glitching Windows magnificently, generated a kind of error that lasts even after three complete reinstalls of Windows.


The overclocking situation has already been resolved, but this bug still continues





Here it's showing an incorrect nominal clock






Here it's showing some glitch memory stats on the right

Task Manager Incorrect CPU Usage

So for roughly the past couple of weeks, I have been having issues with task manager giving me incorrect readings on the CPU usage. Before noticing this issue, I have been running my 9900K at 4.8 GHz all core with an AVX offset of 1. Initially, reducing
my clock speed by 100 MHz down to 4.7 GHz all core (AVX offset 0) solved the problem for a couple of weeks, but the problem has now resurfaced despite the CPU literally running at specified stock speeds.

The Task Manager program is incorrectly reporting CPU usage spiking up to 100% at times, sometimes accompanied by the display turning into a black screen for a half-second while playing SCP: Secret Laboratory. Meanwhile, other programs that were running
at the time such as Google Chrome or DIscord turn into black windows and require restarting. Other programs such as HWiNFO64, Corsair iCUE, and Process Explorer are reporting much lower CPU usage percentages.

Any ideas on what is causing Task Manager to behave like this? I thought Windows shipped out an update that fixed the broken Task Manager, but apparently not for me. I have already tried a clean installation of Windows 10 Pro to no avail.

CPU: i9-9900K @ 4.7 GHz all core

RAM: 4x8 GB @ 3200 MHz, XMP I

Motherboard: Asus ROG Maximus XI Formula, BIOS - American Megatrends Inc. 0905, 4/10/2019

Windows 10.0.17763 Pro Version 1809

OS Build 17763.437

This was taken while running a game (SCP: Secret Laboratory, SCPSL.exe). Something seems off with the process explorer too since the game should be the highest in CPU usage, and the CPU use of the processes don't add up to 100%. I have seen this occur when
the computer freezes for a half-second for no apparent reason.





This was also taken while running the same game mentioned above, except this time only the Task Manager is reporting an incorrect CPU usage while Process Explorer says otherwise.





This image shows Task Manager claiming that the CPU frequency is being throttled to 3.6 GHz. CPU-Z is reporting a clock speed of about 4.7 GHz. Task Manager also seems to think CPUs #8 and #9 (starting from #0) are going crazy. I've checked both CPUs in
HWiNFO64 and Process Explorer and found nothing wrong with them.





This image is another example of incorrect CPU usage where the actual CPU usage is much less than 50%.

Windows Task Manager has never been known as "extremely" accurate. More like a consistent gauge. Since 1809 Task Manager has been known to be a little more inaccurate, though still consistent. And has remained so though there have been a few minor changes to
improve Task Manager in Windows Updates.

Windows 8/10 showing a slower Memory Clock speed in windows task manager

And so i am learning new things everyday, a learning a minute

I was wondering why windows task manager was showing a slower clock speed in the memory selection. Now mind you i have a AMD FX9590 system with 16 gb of Random Access Memory that is 1866mhz out of the box. the bios is even set in the XMPprofile1 to 1866mhz.
but when you open windows task manager it shows 667 MHz. i searched the web thinking that wasn't correct, and i found some Microsoft Community Forum pages that do not have the correct answers. and the i found this forum post and it answered my question in
my quest to find the answer that wasn't in Microsoft Answers. ; Ram is running slower than stock speed

In short they are saying that what is said in the windows task manager memory section is that is the base speed of the memory. Voila answered!!, because that is half the speed of the 1866 MHz. to validate that answer select CPU in Windows task manager and
look in the same spot the speed is it says Base speed of the CPU. Windows task manager is not reporting anything other than the reported base speed of that product in that area of windows task manager.





CPU Base Speed;





I think people are looking at all that cool current data and expecting there to be current data everywhere. the subject here is that the right hand side has no current updated speed of either the CPU or the Memory. and so i have to say to Microsoft; How
about some current speed of the Memory since there is current speed of the CPU on the left side in the CPU Selection of W.T.M. and so here is where i began this bottom paragraph, people see that there is a current up to date reported CPU speed on the left
then go to the Memory thinking, where is my current up to date reported memory speed!

Thank you all, and happy computation
