Problems Flashing 6850's

I'm trying to flash my Visionshit 6850's with some new BIOS to try and bump up the voltage. They are water-cooled, and I can support the increased heat load. Now, I cannot but up the voltage via software because this is a non-ref board. The CHiL chip is not there. Hell, even the mosfets are in different places. Visionshit went so far to cut costs (and have the highest prices) that even the chocks aren't even the solid variants. Even with these disabilities, I'm determined to get more out of these cards.

I have been using ATIFlash and the RBE tool to modify the BIOS. I cannot get anything other than the original BIOS to work. I cannot even change the freqs without getting a BSoD during boot. Also, both cards look identical but have different BIOS chips in them as well.

Am I doing something wrong, or did I just buy some shit boards?

FYI: I have not even broke 45c on either one of the cards at 900Mhz
 
If they are non reference cards, and visiontek did not provide a voltage tuning software with the card, I think you are SOL. It is very possible that you aren't going to be able to adjust the voltage via software ever.

I'm not sure how RBE handles a non-reference bios, but it sounds like a recipe for disaster.
