Maximum PC: You know that friend of yours that can't help but to go over the speed limit at every opportunity? That's G.Skill, a memory maker that's heavily involved in the overclocking scene, and with DDR4 RAM being relatively new, there's plenty of uncharted memory frequency territory to explore. A month ago, G.Skill set a DDR4 memory record by taking a single 4GB module and pushing it to 4,255MHz. And this month? G.Skill broke its own DDR4 frequency record by hitting 4,355MHz.
