Intel Core 2 Duo E4600s are dual-core processors installed in desktop PCs. CPUs (Central Processing Units) are a driving force behind computer performance. A faster CPU means a faster computer. Processors like the Intel Core 2 Duo E4600 have default speed limits installed by the factory, but can often be overclocked to push them to perform past the default speeds. Settings in the PC connected to the processor are changed to overclock the CPU. The front bus speed and the front bus frequency multiplier are changed.
