On the back of the card you’ll find three sealed switches (you need to unpeel the tape to use them) that unlock voltage options, allowing you to push levels of power through the card that would be unsafe with air-cooling. Next to these is a BIOS switch, which activates a secondary cold-bug-proof BIOS especially for LN2 overclocking. MSI told us that all of these switches are only for use with LN2 cooling, and should not be used unless you have an ample supply of the cold stuff on tap.

The exposed switch is for standard, high performance and a bios to be used later.

The High performance switch unlock your Afterburner settings. Shut down your rig, move to the HP position and reboot, check out AB settings

i had to flip the switch on mine before it would let me overclock it using msi ab. where the switch was at when i opened the box would not let me overclock.

the secondary bios switch will allow a higher OC.

I would suggest your read the OC guides that are here and follow those suggestions on the regular setting before you change the bios switch and possibly over volt your card.
