    Highlighted Features of this Motherboard

    Meet the new speed king

    USB 3.1 allows for speeds up to 10 Gbps, doubling the speed compared to USB 3.0 and 20x faster than legacy USB 2.0. USB 3.1 is even faster than SATAIII! Transferring your favorite games, music and movies over USB has never been faster.

    Push your SSD to the limit

    Enjoy a blazing fast system boot up and insanely fast loading of applications and games with selected MSI motherboards. We offer the next generation of high speed storage support through M.2 and SATA Express. M.2 and SATA Express transfer data through a PCI Express 2.0 x2 interface up to 10 Gb/s, making it 67% faster than SATA 3.0 solutions.

    Optimized for multiple graphics cards

    With a large number of PCI-Express 3.0 x16 slots for every MSI motherboard, you get to choose optimal placement for your graphics cards for better fitting and airflow up to Quad SLI/CF. That way, you can enjoy the best graphics at the highest framerate jumping off from your screen when running a NVIDIA® SLI™ or AMD CrossFire™ setup.

    OC Engine

    Run into unstable situations when pushing your CPU to the limit? This occurs because the internal clocks are linked through the 100 MHz BCLK strap. Thanks to a integrated Clock Generator, MSI® motherboards support more flexible BCLK adjustments, from 100 / 125 / 167 MHz straps. Using these straps prevents system crashing while overclocking on the edge and opens doors to achieve the absolute maximum.


    MSI® engineers made sure you can enjoy high speed DDR4 compatibility. DDR4 brings higher memory speeds at even lower power usage as low as 1.05v. DDR4 offers higher volume sticks, this means larger memory configurations are possible up to 64GB.


    Reward your ears with true quality. Get ready for ear-drum shattering sound, with MSI Audio Boost! With Audio Boost we're delivering the highest audio quality so you can enjoy crystal clear sound and music in games. Because the complete audio circuitry is isolated from other features, you'll enjoy less interference and more stability. The built-in headphone amplifier allows you to use studio-grade headgear and get the most amazing sound quality out of your PC.

    OC Essentials

    A small set of tools that are essential to get the best performance out of your motherboard. These features increase stability, assist in trouble shooting, allow you to keep your complete system in check and allow for simple management. This way you can keep your mind on overclocking.


    We put extra effort in increasing customer satisfaction. Our RMA rate has drastically decreased in the last few years. To achieve the highest quality the MSI Overclocking motherboards are developed by our most senior engineers on the most advanced production lines. We are continuously improving our customer services, so in case you might run into a problem you can be assured we offer a fast response to your questions and hand you in depth information on the subject..
