The NVidia Chipset will be a highly overclockable chipset. TheInquirer’s sources confirmed that the Nvidia Pentium 4 chipset will go up to FSB 1200MHz, using 300MHz rather than 200MHz multiples.It goes up to FSB 300 without major problems. Intel 915 and 925 chipset cannot easily get to those speeds. For the record, an FSB of 300MHz means that in quad pumped Pentium 4 mode it actually works at 1200 MHz.
