Patriot Viper Elite 3200MHz CL16 PVE48G320C6KGY 2x8GB DDR4 Review: Overclocking for All

Test Setup, Overclocking and Benchmarks »

Patriot Viper Elite DDR4Using fast DDR4 memory was a privilege only a few could experience due to high cost initially but supply outpacing demand finally resulted in reasonable prices. Patriot’s new Viper Elite DDR4 modules are a welcome addition for Haswell-E as well as Skylake systems. What makes it even more appealing is that these kits are built to be even better performers than the previously released Patriot Viper 4 DDR4 modules (reviewed here) and are very affordable.

The Patriot Viper Elite DDR4 memory kit is available in dual-piece kits of 8GB, 16GB and 32GB with speeds ranging from 2300MHz to 3200MHz. It carries a lifetime warranty and is available in red, blue or gray heatspreader color variants.

The Patriot Viper  Elite DDR4 kit package comes in a two-piece design consisting of an outer box and a see-through blister packaging inside. Users get a full preview of one of the modules on the front and back through the box cut-out. Inside the protective plastic packaging with the modules is a “Powered by Patriot” sticker. This sample in particular is a dual-channel 3200MHz CL16 kit that comes in a pair of 8GB modules (16GB kit) with a gray spine.

Each Patriot Viper Elite module measures 6.8mm x 133mm x 43mm, factoring in the aluminum heat spreader. Other than the gray, red or blue painted spine, the rest of the heatspreader is a shiny aluminum at the top and black towards the bottom. The top spine has partial airflow pass-through from the side.

Looking from the bottom reveals that the 8GB module is single-sided and removal of the heatspreader reveals the IC to be Samsung K4A8G085WB. The aluminum heatspreader is very easy to remove and the adhesive did not need to be heat treated for easier removal. There are no screws holding the heat spreaders or the spine in place like it is on the Patriot Viper 4 modules which has a more substantial heatsink.
