Lost overclock when re installing Windows 10

]Overclocking my i7 6700k with Asus Z170 Pro Gaming mobo. Socket 1151.


Hi, I have a Windows 10 - 64 bit i7 6700k Asus Z170 mobo 16GB Corsair memory DDR4 2400MHz. Cooler Hydro Series H100 liquid cooler.
I am interested in getting back my overclock status that was done by the makers of the computer.
Can anyone help me [a novice] to overclock this system safely?
Thanks to all.

Hi Mike,
Many thanks for your reply. I realise I shouldn't have lost it but I have:-( My rig currently runs at it's default speed of 4.00GHz whereas it originally ran at 4.5GHz.

Most OC is done in the BIOS so you shouldn't have lost anything by reinstalling OS.

BIOS > Ai Tweaker > CPU Core Ratio = Sync All Cores > 1-Core Ratio Limit = 45.

Also, make sure you don't have any power saving options enabled.

Many thanks zebarjadi.raouf for your suggestion. I will have a look in my BIOS and hopefully translate your suggestion into reality

Went into my BIOS and was able to change the first setting but when I went into 1-Core Ratio Limit it will not allow me to change the setting from "Auto"
