I successfully powered on my system and at the boot menu of my msi z370 a pro motherboard the overclock has been turned off but when I enter windows 10 at the task manager window the cpu is running at above 4 GHz but I know the default speed of intel 8700k is 3.7GHz.

 

But before installing I set my motherboard settings to optimised defaults F6 key but the overclock button on the bios menu is turned off. How come I am seeing this 4GHz speed.?

It can turbo up to 4.7 GHz. Basically it wasn't at complete idle (probably downloading updates int he background or something), but it wasn't completely under load either. So it went to 4Ghz.

Want to know which mobo to get?

Spoiler

Choose whatever you need. Any more, you're wasting your money. Any less, and you don't get the features you need.

 

Only you know what you need to do with your computer, so nobody's really qualified to answer this question except for you.

on "stock settings my mobo runs the cpu at 4.3 with turbo boost and mce on by default, so out of the box gigabyte gaming 7 has a moderate overclock, but you need to dial the voltage back some. I can run 4.3 with 1.17v max temp 63c under 100%load for 20 mins...but i cant get 5.2 or higher stable.
