The Katmai 550-MHz processor also offers minimal overclocking potential due to its 5.5× internal multiplier. Most Katmai 550 models will reach their maximum overclocking rate around 575 MHz, just beyond the default core rate of this chip. Accordingly, the retail Intel heatsink cooler should prove adequate for overclocking this processor.
