The fact that we were able to reach 4.4GHz without having to use a water-cooling system is impressive. However, while 4.4GHz is a huge achievement for this E8400 processor, we are just as impressed with the 3.6GHz overclock. At this frequency the E8400 almost ran no hotter than it did at 3.0GHz, as we were not required to adjust the voltage in any way. Furthermore, at 3.6GHz it is possible to get away with using cheap DDR2-800 memory. For gamers the best performance gains can also be seen when going from 3.0GHz to 3.6GHz, as pushing the processor further only accounted for very minimal performance gains!
