My 8700k stock frequency stops at 4.3 Ghz

Hello,
I recently bought 8700k and paired it with Gigabyte gaming 5 motherboard. In stock configuration it should go up to 4.7 Ghz when only a single core is being pushed, and 4.6 when 2 cores are utilized, 4.5 when 3 or 4 cores... and so on until you get 4.3 when all 6 cored are active.
But my 8700k decide to not go above 4.3 in any case, no matter the number of cores stressed at a given time. I run HWmonitor to keep eye on things and it shows only max of 4.3 Ghz frequency at all times.
The temps are pretty good (30c idle, 50c gaming) and I have enough juice (850w seasonic psu).
I don't overclock and kept all the bios settings on default (Auto). In the "advanced frequency settings" the turbo boost technology is on auto and all the ratios are set to intel specs.

What could be the issue? please somebody with Gigabyte z370 motherboard and 8700k test and see if he gets the same behaviour as me. I want my cpu to boost up above 4.3 when conditions allow.

Thx.

What are you using to push your 8700k?

Never really checked my sock speeds on my 8700k just went straight to a 4.9ghz overclock on my Gigabyte z370 Gaming Ultra, checked it with CPUz stress test, watched the core temps stabilise and made sure voltages were below 1.4v and haven't looked back.


Turbo boosts by how many cores are active.
