At the beginning of January this year, Patriot launched their Viper 4 line of DDR4 memory. The kits are designed for Intel's X99 chipset and come in varying quad-channel capacities and speeds. Today's review sample is the 16 GB DDR4-3000 MHz kit (PV416G300C6QK), which consists of 4X4 GB modules. The Viper 4 series falls in the middle of Patriot's DDR4 offerings - below the Viper Extreme Edition and above the Signature Line. Patriot has been in the memory game for many years and has released impressive enthusiast-level memory kits during this time. Let's have our first look at Patriot's Viper 4 memory and see how it stacks up against the competition.
