The DIMM design chosen over the SODIMM design means that the module is larger than it could be (in two, three, four or six pieces). The Corsair Dominator line of memory modules boast maximum over-clocking capability, so that the speed of your computer's performance will be improved by this unit. These internal memory units also come equipped with Corsair's Dual Heat eXchange (DHX) technology. This technology uses a specially-designed heat spreader to remove excess heat from the entire unit, thereby avoiding memory failure and lockup. Some models in the Corsair Dominator series have an AirFlow fan unit, as well.
