I don't have a PII-450. Fritzmarks on a PII-400:

                    Junior 5 128MB            Fritz 5.32 192MB

               Short           Long            Short      Long

100 Mhz         254             262             257        290
112 Mhz         291             315             289        324

Short Fritzmarks are higher with smaller hashtables. For instance, with 64MB
Fritz 5.32 gets 265.

This overclocking is an easy way to gain speed. I am not all that concerned
about the chip lasting 7 years instead of 10, because by then not even my child
will want it. What worries me is the timing problems and program errors
mentioned by Bob.
