This HyperX Predator kit combines moderately high speed and capacity with low timings. The question is, how high can we push it and how low will it go?

A few trends have emerged as DDR4 data rates have pushed through the theoretical ceiling of current manufacturing technology: First, we saw motherboard manufacturers push extra voltage into the memory signal, usually without showing it in their monitoring apps, to convince us that their boards were superior at memory overclocking. And then we saw memory vendors use those higher-than-shown voltage levels to advertise stuff like 1.35V DDR4-4000 that required a “specially approved” board--which just happened to be one of several that pushed 1.37V or more at the 1.35V setting. You’d think a quality-focused brand would avoid such shenanigans. Well, we're here to tell you that one has!
