Hello! is there currently a modded BIOS for I9 9900k with ASUS Sabertooth Z170 Mark 1 ? 

 

 

 

yes but you have to make it yourself. I used 3 different tools and dont remember which ones.

I Think one was was russian and one chinse and the 3rd one coffee lake bios mod tool by revlaay.

It was in the early days of the mod back in i think 2019. Asus is very tricky compared to others. Dont know if its easier nowadays

My 9700kf was running on z170 pro gaming so i am pretty sure it should be possibel on yours. I had to short and isoloate contacts on the cpu. Toke me about 2 weeks to get it to run like i wanted but its was very strong at 4.7 ghz

i used coffee lake bios mod tool by revlaay
and i think some weird chinese tool asweel where i wasnt able to read anything to get the rom ready for my specific mainboard.

They are the best.

Buy the CH314 a with the adapter cable or you will 100% regret it like. All pins on my bios chip where broken i but i managed to run that cpu 100% stable but i trashed the mainboard ripping the pcie slot off the pcb. Upsi.
