Strategy

In stark contrast to the E series of Coppermine processors, the 133-MHz frontside bus Pentium III EB offers poor overclocking potential. The internal multiplier value of the processor decreases in the series. Even the best Pentium III motherboards commonly lack the ability for stable operation beyond the 150-MHz front-side bus speed. Some boards claim support exceeding 166 MHz, though this is more a selling feature than a practical solution for Pentium III overclocking.

Even at the 140-MHz front-side bus speed, the 533EB allows processor overclocking to only 560 MHz. Even under the best conditions, the 533EB will prove troublesome at core operating speeds exceeding 600 MHz. Cooling and voltage will be minimal concerns. The motherboard will present a greater challenge than will the processor.
