Actually no - the person nipped it earlier - I forgot to say that going to a higher FSB and having to sacrifice latency, especially 1T. Although a sacrifice of cas2 to cas2.5 is no worry for the majority of overclockers (of course not those looking to be top 10

)
Although, now you mention memory dividers I guess why not run at 300HTT if you can. Then run your memory at a speed where you don't have to sacrifice latency.
And yes, before you ask the nubbishness over the practicalities of HTT is becuase I'm still in socket A world with a 2500+ mobile.
