Patriot Announces Enthusiast Class DDR4 SO-DIMM for Laptops

Posted by at 11:48 am on June 8, 2016


Patriot Memory has introduced its first enthusiast-class DDR4 SO-DIMMs for high-performance-notebooks and small form-factor PCs. The new Patriot Viper modules will combine fairly high clock-rates with decent capacities, thus, enabling users to build SFF systems with up to 32 GB of memory and up to 44.8 GB/s of bandwidth.

The Patriot Viper family of DDR4 SO-DIMMs includes individual modules with 8 GB and 16 GB capacities rated to operate in DDR4-2400, DDR4-2666 and DDR4-2800 modes with CL15/CL18 latency settings at 1.2V. Patriot will sell the modules individually as well as in dual-channel 16 GB and 32 GB kits. The modules feature SPDs that contain XMP 2.0 profiles, which simplify memory overclocking beyond JEDEC specs. Like other Viper-series memory, the new SO-DIMMs feature the company’s signature red aluminum heat spreader.

Patriot’s Viper DDR4 modules for notebooks operate at 2.4, 2.6 and 2.8 MT/s data rates, which are not officially supported by today’s Intel Skylake microprocessors, but which can safely work in modern laptops and Intel NUC-like PCs with decent cooling. The high-speed DDR4 SO-DIMMs will be particularly useful for systems that rely on Intel’s higher-performing integrated graphics cores because they increase maximum bandwidth available to the CPU to 44.8 GB/s, or by 31%, from 34.1 GB/s offered by two DDR4-2133 sticks, a good thing for bandwidth-hungry iGPUs.

Right now only Patriot and G.Skill currently offer DDR4-2800 SO-DIMMs for laptops. Other makers solutions top out around at 2.4 – 2.66 MT/s.

Patriot plans to start selling its Viper DDR4 SO-DIMMs on June 10, 2016, worldwide. One 8 GB DDR4 module will retail for $34.99, whereas a 32 GB DDR4-2800 dual-channel kit will cost $169.99. Those, who plan to use modules in dual-channel systems should acquire matched pairs of modules with appropriate timings.
