The 2.4GHz is achieved by running at a 9x multiplier at 266MHz FSB. We initally thought that 4MB L2 cache would be shared between the two cores on this CPU but the motherboard BIOS reported 8MB as total L2 cache which means 4MB per core. As per our knowledge, the E6600 will somewhat be placed in the middle with the E6700 (2.67GHz) and X6800 (2.93GHz) above it and the E6400 (2.13GHz) and E6300 (1.83GHz) below it.
