My reply to a post at XS, may be helpful.

I have this same card. I purchased it because it was ~$30 more expensive (for me, where I shop) than a reference card, and it comes with a dope cooler. I recently stopped using liquid cooling and am back to all air cooling.
I have a question that maybe you can answer about the BIOS switch. I almost RMA'd my card because my system wouldn't POST, and it had to do with the switch position.
If you orient yourself with the switch so that you are looking at the back of the card, and the switch lever is pointing at you (I edited your PIC), the Left position will not let my system POST, the Middle and Right work just fine. What is the difference between the Middle and Right positions?
Is it like this:
- Left = Not Used
- Middle = Performance Fan Profile
- Right = Quiet Fan Profile?
I wish I were an "expert user" so I could figure this out; I called MSI and they treated me like a dumbass instead of just helping me find the information.
As you can see, the information that came packaged with the R6970 Lightning is lacking. The position of the switch in this picture is the same position that won't let my system POST; the VGA_LED stays lit solid.
MSI actually saw your post and sent me an answer to this. They'll also be including this in the FAQ for this card. Gotta love MSI's support :up:
L = Reserved for Future Function (Switch to this position, the external device is needed to boot up the card) … currently, no design, so if you switch to “L”, the card wont be able to boot.
M = Boosted BIOS setting to 2.5x PowerTune Range and Maximize CCC limit for higher overclocking capability.
R = Default BIOS setting
