Earlier this month when we published our review on the Intel NUC NUC5i5RYK we tested using a 1600MHz DDR3L 1.35V memory kit. We found the new Intel Core i5-5250U Broadwell-U processor was a very capable processor with a standard 1600MHz kit, but a number of readers were quick to ask about the performance gains that could be gained from using faster clocked memory. It turns out that right now there is no price difference between a Kingston HyperX Impact Black 8GB 1600MHz CL9 memory kit versus a Kingston HyperX Impact Black 8GB 1866MHz CL10 memory kit. Since both DDR3L SODIMM kits are the same price we have a feeling that most people are going to want to go with the 1866MHz kit despite the slightly looser CL10 timings. Read on to see how the NUC performs with both 1600MHz and 1866MHz memory kits!
