Thanks man. As it turns out, the issue isn't that the Asus BIOS is incompatible with Sapphire cards. It's that one or both of my Sapphire cards is weak sauce. It's allergic to the increase in core voltage, which is just weird.
Following your instructions, I created an RBE edited version of my own unlocked BIOS, using 1.175. Unstable, just like with your BIOS, and just like with the 6970 BIOS.
So then I took your BIOS and downgraded the voltage to normal, and now it's stable and I unlocked the CCC OC limit with the Asus software. Of course, don't know how much of a point there is to it since I apparently can't even raise the core voltage.
I have never heard of the simple act of raising voltages making something unstable. I also tried 1.25 voltage but that wasn't even bootable. Definitely not a power issue and definitely not a heat issue, since I'm water cooling and I ran insanely OC'd 470 SLI on this PSU.
Sucks for me I guess. On the other hand, OCing Cayman doesn't actually seem to help much, since it's a very efficient design.
