Overclocking is generally done with the 100MHz based CPUs since there is a lot of headroom for the PCI/AGP buses to max out at around 150/160. And since the multiplers on EB chips is lower, the actual percentage gain is a lot less if the FSB increase is the same. But one guy on that site claimed he got a 193 FSB and stable at stock cooling. Is that even possible? 🙂. Oh well - a bunch of people have gotten up to the 900 mark, so as long as your memory and PCI cards can handle the stress, you can probably squeeze at least another 150 out of that system. G'luck! 😉
