he cant RMA you dumbass, any gpu with a modified bios gets claims denied automatically and then you are SHIT out of luck. tired of people handing out super crap information without knowing shit. anyone with half a brain and has RMA'ed a gpu before knows that you CANT rma a gpu with a modified bios as they check it and will deny your claim, its in there fine print and its also stated before you submit the RMA form. its all there in black and white
And you are a kind of people that didn't read before comment. Just look at to link that I gave to OP (bolded), scroll down a bit msg #33. Someone with bricked GPU (after modded of course) tried 1-8 jumper method and failed. Then RMA-ing it without issue.
You call someone as dumbass easily. Please respect other.
Or may I need to quoting here, so you can see that clearly:
If you're certain it's bricked and next step is RMA, then try the paper clip trick. Scary, but worked on mine (flashed the wrong bios)...
My card is still under warranty, so I'd rather not try this.
tried this, totally not worked on my reference card, It seems its really dead, already sent to my supplier for warranties and guess what, they don't ask if its modded or not.. Lol 
I laugh hard reading this..
Actually the OP and I have different scenes, My card is totally dead that couldn't even detect in Bios, there were no signs of fan spinnings or LED lights
so basically I've got no problem RMA'ing it (they can't test if its modded or not)
@OP,
you don't do the jumper thing, just reflash your GPU with the correct Bios and you're done.
