Windows 10 detecting wrong CPU frequency

str4vag

Hey

I am trying to upgrade my Win10 to the anniversary update. However, the update assistant says that my CPU is not compatible. It seems that Windows only detects my 4690K running at 0.80GHz all the time. CPU-Z and Asus AI Suite detects my CPU at 4.2GHz. 

 

Is there a way to get windows to see the correct clock speed?

800 MHz is the speed it will drop down to when it doesn't need to do anything difficult.  The upgrade tool should be able to detect the full speed it's capable of regardless though... very strange.  If you run an intensive program, do you notice the speed step up or does it never go above 800 MHz?

If you can read this you're using the wrong theme.  You can change it at the bottom.

Yup. I tried running cpu-z stress test and monitoring the reported frequency on task manager, still 0.80GHz the whole time.

Could just reset your bios and reinstall windows

I edit my posts a lot, Twitter is @LordStreetguru just don't ask PC questions there mostly...

What is your budget/country for your new PC?

 

what monitor resolution/refresh rate?

 

What games or other software do you need to run?

All the time meaning under load?

EDIT: obviously. You wouldn't happen to have an ASUS MoBo would you?

Asus MoBo. Maximus VII Gene. Is this a known issue with Asus MoBo?

No change when doing stress test via CPU-Z

Is that the only solution? I really want to avoid going that route.

Then something is preventing it from ramping up, which would explain why the upgrade tool detected it as 800 MHz; for all intents and purposes, it is (for now).  Usually the first place I'd check would be the Windows Power Options, but for some reason I feel like that's likely not the issue here.  Still, have a quick look ;) 

 

It should look something like this

I would head over to window power options and chose the 'Performance Profile" as this prevent ramping down for clock speed and will run at max.

A solution also appears to be to disable some of the power management settings in your BIOS (UEFI). Find the setting for Set NX Bit (No Execute Bit) & disable it. It might read 'Processor execute disable bit' or similar. Set it to disabled (from auto or enabled). That appears to have fixed other i7 issues with the CPU on upgrades. 

 

If successful, I am however unsure if you should re-enable it, as I haven't the foggiest idea what that setting does!

Did that and no change. already on high performance mode.

I don't have that tool installed.

Will try that later. Currently at work, and I am accessing the home PC via Team viewer. So cannot access the BIOS right now.

Alright well it was worth a try.  Like I said though, I'm not surprised that wasn't the issue.  I feel like there's a setting deeper than any software in Windows... like somewhere in the BIOS perhaps?

Do you have any ASUS overclocking or "central hub" software on your PC?

I have AI Suite installed.

Possibly. Might have to play around with the settings in the BIOS later when I can access it.

Try looking for anything CPU/power management related and see if it makes sense

Going through the settings now. But the apps detects my CPU at my OC clockedspeed of 4.2GHz BCLK at 100MHz and ratio at 42. It should be working fine.

I feel like that about life sometimes, there must a lifestyle that is; deeper!

 

Oh well, to the O/P, if all else fails you re-set BIOS completely you could just re-set BIOS & load the defaults & see if that works, it has a nagging BIOS feel to it (you have set to UEFI not legacy BIOS as well, I made that mistake more than once after re-setting BIOS and forgot to switch it back to UEFI boot, not legacy).

 

Then there is the remove everything except the HDD CPU & GPU & see if that will work (with default BIOS) just in case there is an error with something else, (though that's unlikely given its being so specific about the CPU being at fault).

Thanks. Will see if that works once I get physical access to the PC later today.

Solved this. For now. Got into the bios and turned off speed step and turbo. Currently downloading the update. will revert back to my original settings once the update is done. 

 

 

Thanks guys.
