Unfortunately all those fancy motherboards can't even reach 500FSB with professional overclockers. You need a P35 that's been stripped down to everything but the essentials.
Blah.. not really. I am no professional and I have had a 500FSB capable mobo for over 2years now.. aka P5B-dlx..[dare I mention the DFI 965-s..?]
dual core of course.
You start out on the right track, but then contradict your statement.. 500mhz FSB IS do-able..with Q4 it is still a possibility..and there are plenty of other mobo's out other than a P35 that will hit those clocks. I have already stated the elder [965p] and the later is X38.
I havent done any high FSB testing with the new Rampage X48 or the X3350 I just got my hands on..but I am sure to see higher than ~470mhz FSB [my current highest with my sig'd mobo using a Q6600].
