"Can you do something to overclock the PII 450's?"

You might, but I don't think you'd want to. Normally, OC'ing more than a tiny bit is best left to game or other non-mission critical machines, since you take a risk of damaging the processor.

The reasons OC'ing the 300a is such a special case include the following:

-It is the SAME processor core, on the SAME manufacturing process, as the "real" PII 450s. And experience has shown that these parts do in fact have no problem running at 450.

-The performance burst is atypically massive. Not only are you boosting CPU processor speed by 50%, but you're also boosting the memory subsystem by the same amount (66 to 100 mhz.) The benchmarks at Tom's hardware and elsewhere speak for themselves. Were you to OC a 450, say to 500 or even 550, the memory speed would stay the same.

-the l2 cache on the 450s is probably running very near its max speed (remember that it is NOT on the chip, unlike with the celerons.) This makes it much more likely that errors will occour with even modest OC'ing.

Hope this helps,

Dave
