The E series Pentium III Coppermine offers great overclocking potential for systems featuring chips with low multiplier values. Being a 100-MHz front-side-compatible processor, the 500E is a superb candidate for overclocking to 665 MHz, with its 5× internal multiplier, via a jump to the 133-MHz front-side bus rate. Relatively low wattage demands, combined with a high thermal tolerance, often allow overclocking of this processor using the retail Intel heatsink cooler. Systems offering 133 MHz motherboard bus support require little user intervention because core voltage values increase only 5 to 10%.
