Wow reminds me of getting the 4870x2's when they first come out. Nothing but driver issues. Once the drivers mature I am sure you will be tearing up the benches.
I know on my R2E and Classified for 2 x 2GPU cards I need to run IOH Vcore around 1.375 to 1.4 and IOH/ICH around 1.55 to 1.75. Anything less and it will fail tests as soon as I put a small OC on the system.
