Sampsa and Kamu have done both co2 and ln on 2x 6800gt.

Use Rivatuner to fix the sub25º bug, in the overclocking tab enable Force Constant Performance Level to Performance 3D, not sure if that works on all boards, it works on my Gainward's 6800U.

Thanks bro :toast: .But Rivatuner?I think it only takes effect when windows is starting,So does it means i have to poweron without dryice?

no you just cant overclock the videocard beforehand. but dont think you can anyways.

More details pls???
Do you mean:
1--At first , mount the cannon without dryice on to 68u chip
2--then poweron system with 68gt default clock
3--Enter windows ,open rivatuner and enable Force Constant Performance Level to Performance 3D.
4--then Drop dryice into the cannon & overclock 68gt.
