This applies to all overclocking boards in general. Every board that overclocks will have a "strap" somewhere, where the FSB frequency will exceed the boards capabilities at certain latencies (usually on the northbridge), and the latencies will be loosened. As the frequency increases pass this loosening point and on to the next, relative ratio of performance increases.
As chozart said 7 months ago, its like RAM.
Theoretically, RAM that has to drop its latencies from 4-4-4-12 to 5-5-5-15 at 900MHz will run much better at 4-4-4-12 899MHz than 5-5-5-15 900MHz. But as clocks are increased towards the next strap, lets say, at 1000MHz, performance ratio's increase. 5-5-5-15 999Mhz would run faster than 6-6-6-18 1000Mhz.
And overall, the higher clocks prevail, as long as it doesn't rest too close after the strap. In other words, don't pass 900Mhz unless you plan on passing it by a lot, say to 930+Mhz.
Hope I didn't confuse too many.
