In this review we looked at the Viper Gaming Viper 4 Blackout Edition memory modules from Patriot. These are a performance memory kit designed for both Intel and AMD platforms and come in a variety of speeds and capacities ranging from 8GB up to 64GB. The modules featured in this review are a 64GB dual channel kit clocked in at 3600Mhz with densities of 32GB per module. The 3600Mhz frequency makes them a perfect match for the AMD Ryzen platform when the Infinity Fabric is set to 1:1 and a nice match for any modern Intel processor.
Overall performance was extremely good and very predictable. The 32GB modules are dual sided meaning that chips occupy both sides of the memory module and will limit overall frequency and increase latency over a smaller capacity module. This can be seen in our benchmarks where synthetic showed the Viper 4 modules slower than lower capacity versions however, when it comes to overall system performance having more memory is generally a good thing.
Personally I am a fan of the aluminum heatspreaders. They are completely black with a ghosted version of the Viper logo on each module. The metal is more than a thinly stamped piece of aluminum adding weight and the appearance of quality to the module. Across the top you’ll find a dual row of heatsink fins that is used to clamp the heatspreaders together. Sadly, my modules featured a manufacturing defect where the factory installed heatspreaders intended for a single sided DIMM module instead of one with thermal pads on each side. Overall this gave the module a much wider profile but didn’t appear to impact performance or fitment.
