I noticed tomshardware.com has no "how to overclock your 300A". I did note that there are some notes about Intel putting a stop to overclocking by locking the chip at one speed. Anyone have the lowdown on this? I need a new machine at home, and I'm seeing the Celeron and the AMD K6-2 coming really close in price. If it's possible to reliably clock the celeron, that seems like a good deal... Anyone able to clarify the rumors?
