I wouldn't expect to get DDR 433 speed out of that at those timings, after all, it's 2700 RAM, not 3500. You'll have to ramp down the memory if you boost your bus. Some tweaking will be required. The best memory out there is gonna have to be ramped at high FSBs.
However, I'm sure you can get it to work at some reasonable speed, just not the fastest out there.
