The Pentium 4 Willamette 1600-MHz processor offers great overclocking potential with minimal concern for system instability. Nearly all P4 1600 models can reach 1900 MHz straight from the retail box, without any significant increases in core voltage rates. However, cooling becomes a dominant concern beyond 2000 MHz, as this chip features a maximum core temperature threshold of 75° Celsius.
