<< The cpu doesn't "hit the high fsb", your memory/fsb bus does. So to answer that question, NO I don't think many can. Not many people have had success above 160FSB on a DDR motherboard. However on my KK266-R (KT133a) I can do 167FSB. 😉 >>
I'm confused, assuming you have a 1/5 divider and your memory can hack it, all PCI components are still in spec (dunno 'bout AGP 'tho) so what would be the problem? Im a couple of generations behind (P3-700 @ 933, Asus CUSL2) but will be upgrading soon so I need an update 😉
