The Pentium III 933EB MHz processor is available in two different models, each featuring a slightly different core design. The earliest 933EB chips reach a maximum thermal load of 60° Celsius before core failure, while some later models can scale upwards to the 70 to 75° range due to improved core stepping. Older models will be of the 0686h family, while the latest chips show a 068Ah designator. All the models produce serious thermal loads that require massive cooling for any overclocking potential beyond 1000 MHz.
