Problems Flashing 6850's

[FireBean]

I'm trying to flash my Vision**** 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. Vision**** 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. :facepalm:

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

FYI: I have not even broke 45c on either one of the cards at 900Mhz

[I.M.O.G.]

Are you flashing a BIOS which is known to work with the voltage regulator on those non-ref boards?

I have a Gigabyte 5870 that is very limited, because it uses a non-reference vreg that isn't supported by most methods of modifying the voltage.

I couldn't tell you. I have more thing to try before I give up and stick with a 925 overclock :bang head . What happens is a ATI driver fails during boot up, so I'm going to clean the drivers out, and just see what happens. I'm just glad that I can always flash back to the stock Bios. :rolleyes:
