Undervolt 7700k

[Neeho2]

brand spankin new to SSF soi apologize if I'm in the wrong thread

I just completed ( for the most part ) my mini itx build inside an NFC systems s4 mini...I'm absolutely in love with it but I need some guidance for undervoltage...I put a 7700k in it ( knowing I might see a problem with temps ) and as to be expected I do...not toooo terrible be if I can fix or help it I'm going to
This 7700k is on an asus rog strix z270i
This is my first new build in 5 plus years so a new UEFI bios I'm unfamiliar with is a little daunting...I want to do some careful undervolting without losing (too much) performance
I think it can be done without losing any performance but if there is a small performance trade off I'm willing to make it...I'm prepared to drop voltage slightly, restart, run stress tests, record data, and repeate...I just need a little guidance through this new bios and some professional help would be invaluable...can someone help walk me through this?

Unfortunately I have no experience with that Motherboard, but in general it should be as simple as adjusting the voltage multiplier to be lower, applying it, and testing go gradually, start off with a modest decrease and if it's stable go further. Otherwise cut it in half and repeat. That'll zero you in quickly. Once you're comfortable run a prolonged stress test to be certain and be sure to record your results along the way. More data for the community is always appreciated

I have the same board. Set the offset to Negative ("-") and amount to .05v and keep going in .01v increments. You should be able to go to -.1v (~1.1 vcore) at least. Getting down to -.2v (~1.0 vcore) at stock would be really good. Depends on the chip
