If you bought any CPU expecting it to overclock like everyone else's, then you bought it for the wrong reasons. There is no such thing as a guaranteed overclock. Not all CPU's, even those from the same wafers, are going to overclock the same. The most you can actually count on, is maybe a 10% increase in clock speed, but there are no guarantees. That doesn't mean it's the CPU holding you back. It may be the Soyo board. I'm not entirely versed in the KT333 chipset, so does it even officially support a 166MHz FSB? Not just the memory clock, but the actual FSB. If it doesn't have the right PCI and AGP dividers, you're basically overclocking all of your peripherals connected to the PCI and AGP busses. Hard drives are very finicky about how fast they want to run, and most won't even run the slightest bit out of spec.

Another thing, about what Vert said about the increase in voltages. Any time you raise the CPU clock, i.e. raising the FSB without lowering the multiplier, you are running the CPU out of spec, and supplying more voltage to the core can help solve stability issues. I think there was a link to an article that explained, pretty much in layman's terms, how and why this works, posted somewhere in the forum. I'm also not sure if the Soyo board has the ability to override AMD's multiplier lock with TbredB CPU's, like the nForce2 boards do.

Your memory specs would be useful, too. I assume it's PC2700?
