Admittedly, I have never modified a BIOS before. I have flashed a Mobo, but never changed figures myself. I have found other peoples settings, but not for this exact card. This is why I ask.
There are threads with collections of bios, look there.
If you do not find anything, simply there is not a pre-build one around.
Modify your own bios is pretty simple in 99% of cards, I hope that you are not in the unlucky 1%.
That being said, your card has dual bios, so you can try how many times you need without any concern, just try man!
p.s. Science proved that people people who use the search button are WAY more appreciated on bitcointalk.org
