If you increase the bus speed, you _greatly_ increase the odds of very difficult-to-find system problems. IE SCSI or IDE controllers are very complex. And just because they run at 100mhz, does _not_ mean that they will run at 112.5, for example. And when they fail, they generally fail 'softly'... and just produce bad data. Just visit the linux mailing lists to see the horror stories. If every device in your computer has a 90% chance of running correctly overclocked, and you have 10 such devices, the probability of _everything_ running correctly is almost zero (try .9^10 for a horrifyingly clear data point.) Memory is very sticky. If you are running a FSB at 66mhz, and want to overclock to 75mhz, take your memory to a good local repair shop and let them run it on their tester at 75mhz. You might be surprised that it doesn't certify. Memory is already pushed to the edge...
