its to switch between two BIOSes . One will probably be higher clocked. Just look in msi afterburner, flip the switch, and see what happens. Clock speed will either go up or down.

I have the same card , the BIOS switch switches between Legacy and UEFI bios , it doesnt tamper with the clocks .

Switching isnt dangerous , its used if one of your BIOSes is broken / corrputed , so you can switch to the one which works . 

 

You should do it while the PC is turned off , so turn off , click the button , turn the PC back on . For UEFI bios the button will light up blue , if its not iluminated that means you are in Legacy BIOS

As far as i know , it doesnt make any difference . I have tried both UEFI and Legacy , same overclocking results .
