I just purchase the Z370 Fatality Gaming K6 motherboard with the Intel i7 8086K (5GhZ)

However, Windows 10 tells and the BIOS OC Tweak page says the processor is only running at 4Ghz.

Does this motherboard support the 5Ghz 8086K Intel i7 processor. I did the BIOS update on my first boot up.

Windows 10 Enterprise

Processor Intel(R) Core(TM) i7-8086K CPU @ 4.00GHz

Installed Memory : 16GB

Any help would be greatly appreciated.

5GHz is a TurboBust frequency. If you want always have it on all cores (and you have proper CPU cooler) - make such settings in BIOS:

OC Tweaker\CPU Configuration:

Muulti Core Enchancement = Disabled

CPU Ratio\All Core\All Core = 50

CPU Cache Ratio = 46

BCLK Frequency = 100.00

Spread Spectrum = Disabed

Intel SpeedShift Technology = Disabed

Long Duration Power Limit = 4000

Long Duration Mantained= 3

Short Duration Power Limit = 4000

Advanced\CPU Configuration:

CPU C States Support = Disabed

Advanced\Chipset Configuration:

VT-d = Disabed

Then F10 and Enter.

Should work without any additional voltage regulations. https://www.google.com/url%3csa=t&rct=j&q=&esrc=s&source=web&cd=11&cad=rja&uact=8&ved=2ahUKEwi-387fluPcAhUDQZoKHXuwDjgQFjAKegQICRAB&url=https%3A%2F%2Fwww.tenforums.com%2Ftutorials%2F2843-change-power-plan-settings-windows-10-a.html&usg=AOvVaw0-ozVR586L3S0oh5Pwl04z" rel="nofollow - Change Power Plan Settings in Windows 10 to High Performance.

Always keep your CPU temperatures lower 70*C. Good luck.
