MSI Afterberner, ntoskrnl.exe and dxgmms2.sys - high CPU usage WIn 10

[Bubunya]

G'day guys.
Here is a problem.
For some reason while MSI AB running System in Resource Monitor using up to 25% CPU. In Process Explorer I can see it splits between ntoskrnl.exe and dxgmms2.sys.
As soon as MSI AB if off system gets back to usual 3-5% idle state.
Even in clean boot MSI AB causing this problem.
What could it be? What may cause system to react on MSI this way?
I have identical with almost mirrored system install and there is no problem with MSI AB whatsoever.

I am not using MSI AB for OC, just to monitor temp, usage and fan of GPU thru Rainmeter, that is all. Any idea what may cause such a problem? WIndows 10 Pro, GPU GTX 1050 and I am using 395.69 driver.

Thanks in advance!

Up to 25% on what CPU and at what frequency?

My bad.
i5 7300HQ CPU @2.50GHz
16GB DDR4 RAM
GTX 1050
WIndows 10 Pro

It's running at 2.5 GHz while being used at 25%? The other system also is a laptop?

According to CPU-Z core speed is jumping from 800+ up to 3100MHz while staying between 21% and 25% load
Bus speed is around 99MHz
Core VID from 0/6V to 1.2V

And yes, the other is laptop too. Exact same factory identical aside of boot drive (MX300 vs EVO860) and ram (Dell vs G.Skill)

While CPU-Z was running I'd shut MSI AB off but funny thing is CPU load didn't get down a bit.
It seems like ANY software which has an ability to monitor GPU at any angle cause this CPU load...
Will try to reboot and see what's goin' on.

UPDATE:
Changed driver for on-board cpu from intel to generic windows, updated geforce driver to latest one (which is sucks btw), nothing is seems to be working. Same "System" CPU load while running any of software's that can monitor GPU

It may not be fully compatible with a laptop. If you have the issue with software provided by the laptop manufacturer, then you should contact their support.

What "it"?
Clean system install on both, original drivers on both, same software's and such, all works on one identical laptop, not working on other. What manufacture have to do with it? Just curious...

 

[GhislainG]

"It" is the monitoring software that you use. However if both laptops are identical and they run exactly the same software, then there is an issue with the one that's too busy when you monitor the GPU.

Found the problem if I may call it that way.
The only difference between setting on this two rigs was Intel SpeedStep - on first it's disabled, on second enabled.
Did turn it on on both and CPU usage boosts right up to 25% while using MSI AB.
Turn it off and CPU back to normal 2-3%

AFAIK it should help with CPU load, not cause 20-25% usage, no?
Will gladly accept any recommendations.

That's why I asked about the frequency; when SpeedStep is disabled, the CPU always runs at full speed. When it's enabled (it helps to keep the CPU cooler) it runs at a lower frequency unless it's busy enough to justify higher frequencies. That makes it appear it's busy in Task Manager, but it isn't that busy if the frequency is low. The total processing is the same when you see 25% at low frequencies vs 3% at full speed.

Yes but still - just did clean system install, nothing aside of drivers and MSI AB.
And it still spikes from 20% up to 25%. Last night after another clean install been trying to run HOTS - full 100% load on welcome screen of battle.net. Not even the game.
Could be wrong, but it does not look normal for me. On another identical laptop with SpeedStep off in bios settings I can run same game at 60-70% CPU load.
And, as I said before, in idle mode and clean system:

According to CPU-Z core speed is jumping from 800+ up to 3100MHz while staying between 21% and 25% load
Bus speed is around 99MHz
Core VID from 0/6V to 1.2V

So what's the benefits of SpeedStep if I am not OC'ing aside of power savings?

All drivers up to date, bios updated etc etc.

Since SpeedStep obviously makes you unhappy, then just disable it. You get better performance when it's disabled because the CPU always runs at its rated frequency; you don't need to worry about the CPU temperature if you use your laptop in a normal environment (regardless of that setting it will throttle if it gets too hot) and the additional power draw is not that significant.

I was just trying to make setting right way, that is all
But thanks a bunch for all your time and help, been (and still) googling this problem to gather more info.
Thanks again and have a great day!
