DFI LanParty UT NF4 Ultra-D
 

The DFI LanParty series is legendary among overclockers. We haven't seen any other board offer that many overclocking features. For example, being able to your run your memory at voltages of more than 3.3V is pretty unique. A well thought out components layout and little on-board switches make overclockers happy.
