Patriot Viper Steel Series 16GB (2x8GB) DDR4-4400MHz Memory Kit Review

Conclusion and Verdict

Running ram at speeds higher than 3200 MHz is a tricky but fun process. If you have an “enthusiast-grade” high-end motherboard like the Asus ROG Maximus (IX, X, XI) Apex series, then you should be able take full advantage of these sublime memory modules from Patriot, and run them at the full speed of DDR4-4400.

Using the EVGA Z370 Micro motherboard, I was still able to run these memory modules at an impressive speed of DDR4-4300 using XMP 2.0 profiles with all voltages and memory times on AUTO. Running memory at this speed really makes a difference in terms of performance, especially during our AIDA64 memory test, producing one of the highest scores I’ve seen to date.

In the past, I never really understood the need for higher memory speeds. I thought they were only needed during overclocking … but how wrong was I? As long you have a motherboard that can support higher memory speeds greater than 3200 Mhz (and up to 4400 MHz or higher), then you’ll be able to take full advantage of any high speed enthusiast ram on the market. Now that I’ve seen the potential performance gains you’ll get from higher memory speeds, there’s no turning back!

These memory modules are designed for extreme enthusiasts who want speed and performance. Although it lacks RGB, it does come with some nice looking Aluminum heatspreaders with a sleek gun metal finish, which I really like. If you’re a fan of RGB, then go for the Patriot Viper RGB. They come with speed up to DDR4-4133 (black) and DDR4-3200 (white).

You can buy Patriot Viper Steel Series 16GB (2x8GB) DDR4-4400MHz from various retailers for around USD $500.

Final words

If you want XMP 2.0 compatible memory kits that offers great performance, and be able to run at speeds of up to DDR4-4400, then you must seriously consider the Patriot Viper Steel Series 16GB, and put them on the top of your shopping list. I was to run them at 4300 MHz with ease, even on my Z370  motherboard. Simply select XMP profiles adjust the speed. All voltages and memory times were left at default (AUTO).
