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.

Among large suppliers of memory modules, only Patriot and G.Skill currently offer DDR4-2800 SO-DIMMs for laptops. Other makers are a little more cautious when it comes to high-speed modules for notebooks and SFF PCs, which is why their solutions top 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.

    Good to see atleast Patriot has fallen into ugly rgb led trap.

    As stupid as leds on ram are in general, it would be that much more stupid for laptops where you can't possibly see it and it will only worsen battery life. You shouldn't be commending them for not being 100% mentally retarded, that's just setting the bar too low :)

    Yes! Although, I wish it had LEDs that were bright enough to shine from beneath the laptop's plastic shroud.

    Moooooooooom! My gamin' laptop needs moar gamin' RAM!!!

    Shouldn't the part where it says "Patriot's Viper DDR4 modules for notebooks operate at 2.4, 2.6, and 2.8 MT/s data rates" be GT/s (Gigatransfers/second) rather than MT/s (Megatransfers/second)?

    When are we getting transparent chassis and keyboard so they can show off the LEDs?
  • Michael Bay - Friday, June 3, 2016 - link

    We don`t. LEDs just burn the plastic through instead!
