Many PC enthusiasts use light-up RAM to add a flair to their systems. But creating a proper, synchronized light show isn't always easy. Even if you have the right motherboard, compatible RAM and the necessary software, there's no guarantee of a harmonious display. HyperX wants to fix that: it's introducing new Predator DDR4 modules that can use infrared light to sync their RGB illumination. There's no guesswork and no external cables -- you can just assume your lights will pulse together using power directly from the motherboard.
