A unique system with a unique problem with ATT... -

Hello Ray! I finally narrowed down a problem I was having...
I have two ATI 5870s in CrossfireX. However one is an Eyefinity 6 Edition 2GB and the other a regular XFX 5870 1GB. They both have the same clocks, however the voltage of the 2GB card is 1175 while the 1GB is 1125.
I'm trying to force maximum clocks here, as I have a few games where the 3d clocks don't kick in and instead stay at the 2d clock speeds. I'm running Eyefinity setup with three 19" monitors, and a 50" Plasma TV as an extended monitor. I also have created monitor profiles in CCC for those games that don't run in Eyefinity or Extended mode.
If I create a GPU/mem clocks profile in ATT, and apply voltage and clocks to both cores, I get the wrong voltage set for the 1GB card. This causes me a problem as it runs hotter, and blue screens Adobe Flash player with Hardware Accel enabled (As Flash is trying to set the wrong voltage for the card). I also have a few other programs that have BSOD'd after some extended use...
I did have Software method to read clocks and the Kill Powerplay option checked when I installed the latest ATT.
Right now to get around this, I've created some CCC profiles with Overdrive and the clocks set in the profile (And then edited the XML CCC Profile files to force apply the clocks and voltages). However, I have to activate the profile manually when I start Windows or a game, as it won't start up on boot for me (Win 7 64-bit Ultimate)
Any suggestions? Or could there be a way to allow ATT to control the two cards/GPUs separately?
