I have simillary problem, I can´t run 2x2 ram at 1066 with bus 333, 1066 with bus 400 or 1080 with bus 450.

I can run ram at 1200 with 2x1 at bus 400, 450 and 500.

I can run my ram up to 1100 at bus 550 (dual core), it seems like this board have problem to run ram at ~1050 and higher at anything else the 1:1 with 2x2.

I have tried this with 2x2 Corsair Dominator PC8500.

Have you tried to run 1:1 with yours?
