Well, every mobo and every CPU are unique, one can't tell which settings are the best for your system. You just have to test which suits you best. I've used FSB 240x11, DDR667, 1.95VDIMM and 1.40VCORE, but I can't boot correctly with that setup. System is stable, but has some boot issues, my stable and working setup is FSB229x11, DDR800, 1.95VDIMM and 1.35VCORE. I'm using G.Skill 5-5-5-15 pc6400 2x2GB-kit, so those are the latencies which I'm using. And remember to lock the PCI-E frequency to 100MHz.
