Strategy

The Pentium III 850E MHz is best suited for moderate overclocking via the 112 MHz front-side bus rate. The resulting 952 MHz core operating speed is generally in the range of the 850E's overclocking capabilities. Attempts at higher frequency ranges approaching 1000 MHz will be difficult, even for the best system configurations. The increased efficiency offered by a Peltier or liquid cooling solution will be important if you hope to push your 850E system into the 1 GHz arena.
