it's weird how it works, but even with HTT there's still a FSB of sorts. It just isn't the FSB of old. You still have to set the 'FSB' clock to get the final clock speed. It just doesn't work how the old core 2 duo/p4 and prior architecture works where everything goes through the FSB. It's just the 'FSB' clock determines the final clock speed for the chip.
BUT! It still runs linked to the ram, so if you're running at like a 400 'FSB' clock and its 1:1 then you'll be at 400 mhz for the ram, for example. and for every +1mhz you give to the 'FSB' clock the ram speed increases a mhz.
