That wouldn't surprise me. Low clock rate processors are often high clock
rate processors with the lower clock speed simply enforced. Take a laser
and zap a link on the chip, or simpler yet take a bonding wire and jumper
two pads on the chip.

Or even simpler, get an HB pencil and draw a line to link the pads. I got
nearly a 50% increase in processor clock speed on one of my early Duron
CPUs.

It's worth a try, and is sometimes well-documented as reliable. But
sometimes CPUs are jumpered at one speed because they failed testing
at a higher one.
