Strategy

The Pentium III 650E represents a good option for systems with motherboards lacking official 133-MHz front-side bus support. Even when operating with the limited Intel BX chipset, the 650E can offer easy scalability to 800 MHz with only a moderate increase in core voltage rates. The comparatively high 6.5× internal multiplier of this processor presents real potential for scaling up to 865 MHz with boards supporting the 133-MHz front-side bus rate. Considering the increased electrical demand of the 650E, additional cooling will usually be required when increasing core voltage values beyond a marginal 5% threshold.
