Asus R9 290 Direct CU2 Question

So I'm still new to these higher cards.

I just upgraded from a Sapphire R9 270 and so far love the difference but haven't had all that much time to test it.


I just recently noticed a small switch on the card which is the Dual Bios selector if I am to be correct. My only question is....Which one is which? How do I determine which selection is the Performance mode?

it should be labeled on the back of the PCB, if not check the box. you really won't need to mess with it though, since AMD gives you more control of your card anyways. you can raise the Power Target to absolute absurd numbers
