If you adjusted the voltage and are back to stable thats all you should need.

what should be the core voltage to hit 4.4ghz?

You will see how I use Override with an CPU Voltage Target as shown in my images.
Each CPU and Memory will be different as far as the vCore.
Also make sure your BCLK is set to 100, some XMP Profiles change this to 125 so if this happens set your memory to Auto for now and later set it per your OEM settings.

manage to hit 4.5ghz so far it's stable thank you

I think you did reach the top :)
Maybe insert more fans?

Great News  

Got my hands on a 6850k with an x99 micro 2

Used your settings, bios reports 4,4ghz, windows in cpu z only 4,0ghz
Uninstalled the win 10 silly update, same issue.

Have you updated to the latest BIOS?  If not, you must do this or a micro code incompatibility with Windows 10 will disable overclocking.

Yes as well as removing the update with issues.

No, if you're running the latest updated version of Windows 1809, you do not need to remove any updates as long as you have the latest BIOS. Secondarily, if you already knew this, why are you having issues?

This is why I am here, why does cpu z report only 4,0 with x40 multiplier when bios has 4,4ghz settings?

Have you updated to the latest BIOS and version of Windows 10?
If you're desiring to stay on an earlier version of Windows, you can take ownership of and either rename or delete mcupdate_GenuineIntel.dll in the Windows System32 folder. This will restore overclocking until you either update again or perform a system command such as running system file checker (SFC /scannow for example).
