Originally I thought I got burned by not being able to unlock this card, but you can. Previously I've only seen special edition cards like the Lightning with unlocked voltage. Some special cards have an Auto shown in the voltage slider in MSI Afterburner. Most video cards will not have this Auto feature, which I think is different from the default slider placed at 0. So you wont see the Auto until you follow the steps to unlock the voltage.

Everything in this section and trying these steps in the following video might void your warranty and/or can end with a dead product. One should be aware that trying comes at your own risk.

Go to the actual Youtube page instead of watching the video from here and read the 1st comment I wrote for additional instructions and download links. Then follow the steps taken in the video.
