Dual Xeon motherboards usually have no overclocking feature and overclocking is not recommended for such dual SMP systems, though 4 GHz is a typical number to achieve with 3.3 GHz Xeon. If you want to do overclocking, however, please be careful to choose mother boards and cooling systems. There are not enough space to install two large heatsinks on such boards and usually water cooling is used (with more money :).
