Help with I78700K+Asus Strix Z370i

Hi
So i have a prob with my cpu or the motherboard
with this settings i can get stable with the same cpu on a Maximus X Formula

8700K 5.0Ghz 1.35v
DRAM Configuration
Load XMP........XMP 2.0 Proile 2
Bclk Frequency.........100.0000
DRAM Reference Clock........Auto
DRAM Frequency.........DDR4-?????Mhz
ASUS MultiCore Enhancement……….disabled
CPU Configuration
CPU Ratio.........All Cores
Core Ratio Limit...........5.0Ghz
Min.CPU Cache Ratio............... 44
Max.CPU Cache Ratio...............44
Bclk Frequency.........100.0000
AVX Ratio Offset................3
Long Duration Power Limit.........................4095
ShortDuration Power Limit.........................4095
CPU Core Current Limit...........255.50
Voltage Configuration
BCLK Aware Adaptive Voltage…………………….Disabled
CPU Core/Cache Voltage.......................Manual Mode
CPU Core Voltage Override....................1.350v or 1.360v
CPU Load-Line Calibration .......................Level 5 or Level 6
CPU Current Capability…………………………………140%
CPU VRM Switching frequency…………………..Manual
Fixed CPU VRM Switching frequency(KHz)………………..500
CPU Power thermal control …………………………………….120
DRAM Current Capability………………………………………130%
DRAM Voltage...................................1.350v

For 5.1GHZ and 5.2GHZ
CPU VCCIO Voltage……………………………………………………………. 1.325v
CPU SYSTEM Agent Voltage……………………………………………. 1.250v
Boot Performance Mode……………………………………………………… Max Non-Turbo Performance
FCLK Frequency…………………………………………………………..1Ghz
CPU Core Voltage Override…………………………………… 5.1Ghz 1.45v and 5.2GHZ 1.5v

with Asus Strix Z370i i need 1.45 to get 5.0ghz

This is normal or i'm doing something wrong?

The Maximus X Formula is a much higher end motherboard than the Strix so it uses higher quality chokes, Mosfets etc... that could be the reason you can get better results with the Formula compared to the Strix.

I know is better board
but i have to go a bit high on CPU Core Voltage and i saw some reviews with lower V.

"We were able to easily achieve a stable 5GHz when manually overclocking with the tiny Asus board, and the system remained stable once we’d dialled the voltage back from our initial 1.3V rating to 1.29V."
from kitguru

"The ASUS ROG Strix Z370-I Gaming was able to take our i7-8700K to the lofty heights our 'made for overclocking' board, the Apex, took us. We are again limited by the cooler. Our particular sample is a good candidate to delid as there is a bit of headroom voltage wise, but hit the ceiling on temperatures. Compared to the Apex, the jump from 4.9 GHz to 5 GHz was significantly harder. The Apex needed 1.28V (actual) to reach 5 GHz while the Z370-I Gaming needed 1.328V (software). "

Thanks for the reply xD

That has nothing to do with the board. That's just your CPU not being as good as a reviewers

As NBD said you cannot go by a review as their CPU will be different to yours i.e silicon lottery.
