i have the x hero board and had this question as well when i first got the board . my gigabyte z 270 and 7700k i didnt have adaptive voltage ( damn u gigabyte ) .
anyways once u put adaptive to on leave offset to default and total max turbo adaptive to 1.32 v @ 5 ghz load line =6 , svid support has to be on and svid best case cinario .
after those 2 option my 5 ghz drops voltage and mhz speed not doing much an under heavy loads like prime 95 i get 1.32 v - 1.34 wich is perfect i dont want to lower voltage anyways since i need 1.32v - 1.34v to be fully stable anyways lol it worked out perfectly .
like raja says i dont think u can lower the cpu voltage below that since it reads off the cpu built in svid - correct me if im wrong
if u went to offset mode - wich is terrible for high ocs u might be bale to get below 1.32 v with a higher offset .
offset on my gigabyte z270 was a nightmare i dont even want to think about it ! 5 ghz it was a bad dream
after trying offset on this x hero @ 5 ghz its beauty 0.8 v under light lods and ramps to 5 ghz 1.32v under load
