Corsair's Vengeance LPX line combines blazing-fast DDR4, traditional low-profile design, and aggressive price points to create one of the best platforms. The LPX sticks are designed to fit into standard motherboard slots without interference, even though they are slightly taller than standard DDR4 modules.
A special PCB is used to route both power and data, with the board designed in a separate step from the sticks. The PCB maintains tight tolerances despite the wide spacing between the memory slots. They also feature a heat spreader for better heat dissipation.
