"The recent availability of newer KT133A based boards have stirred lots of
interest in overclocking the Duron 600. Well, from our tests on 3 of the
first KT133A boards available from EPOX, DFI and SOLTEK, my Duron which is
able to do 900(9x100) can easily perform at 800 Mhz and above at 6x133 and
up to 6x140 at 1.7v (you got to do some L1 pencil trick to change voltage if
the board does not support it)."
