Currently OC1 setting only applied to 1070 and 1080ti on BeamHashII algorithm, for all other cards and algorithms this option is ignored.
When it applied miner select alternative kernel version that may better work than default kernel with your OC settings.
Thank you for explaining.
THANK YOU FOR EXPLAINING--
Although the long wait is i still causing me to grumble. I have only a single 1080ti and several nVidia rigs. --scryptr
