I don't even use a mouse in the BIOS. Up, Down arrows, enter, tab and enter numbers. Done. I already have multiple OC profiles saved and now its just a case of the last page and selecting what profile I want to run if I go there. 99% of the time Im on the same set up with a 10980XE at 4.7 GHz all cores. Also have profiles for 4.6, 4.8, 4.9, 5.0 and 5.1
