    Can someone clarify for me? There are two options for increasing the cpu voltage in the bios.

    150mv and 75mv.

    My confusion is due to the way it differs from the RAM voltage which goes sequentially from 1.5v to 1.6v to 1.7v. The cpu voltage on the other hand goes from "None" to 150mv to 75mv which seems intuitively out of order.

    So it's a stupid question, but is the 150mv "One Hundred and Fifty millivolts" or is it "Fifteen Point Zero millivolts"? Can someone clarify haha?

    I guess 150mv is +0.15v over your CPU default max vcore while 75mv is +0.075v over your cpu max vcore.

    If your max is 1.2v for example, selecting 75mv will give you 1.275v, while selecting 150mv will give you 1.350v.
