Protect your Sensitive Components During Installation and Beyond

EXTENDED HEATSINKWith newer processors housing more cores, thermal and power design becomes for important to ensure temperatures remain stable. The MSI B550M Mortar features an all-metal extended heatsink to enlarge the surface area. You can also expect more efficient heat dissipation allowing even high end processors to run at full speed.

Experience Core Boost

FASTER AND UNDISTORTED CURRENT DELIVERYCore Boost technology combines MSI’s premium layout and digital power design which allows for faster and undistorted current delivery to the CPU at pin-point precision. Not only supporting multi-core CPUs, but also creating the perfect conditions for CPU overclocking allowing you to always get the most from your 3rd generation AMD Ryzen Processor.

Give yourself a Lightning Fast Experience

LIGHTNING GEN 4 PCI-EMSI lightning Gen 4 PCI-E is the latest and the fastest PCI-E data transfer solution with 64GB/s of unidirectional transfer bandwidth that has doubled compared to its previous generation. PCIe 4.0 maintains both backward and forward compatibility with older and newer specifications. Optimised by steel armor design and server grade PCB, you can enjoy next-gen devices without any compromise.

Unmatched Memory Performance

ADVANCED PERFORMANCE WITH DDR4 BOOSTMSI motherboards are crammed with features to fuel your system\'s memory with more speed, higher overclockability and increased stability. The technical enhancements of DDR4 Boost allow for more stability at higher memory speeds when compared to other brands. MSI conducts thorough memory testing with the most popular memory brands under extreme conditions to ensure your system runs stable no matter what and with optimised memory traces you don\'t need to worry about your system crashing under load!

Protecting your PCIe Slots

FORTIFY YOUR SYSTEM WITH PCI-E STEEL ARMORMAG B550M Mortar supports multiple GPU solutions. Optimal PCI-Express slot placement allows for better fitting and airflow. That way, you can enjoy the best graphics at the highest framerate jumping from your screen when running an AMD® CrossFire™ setup Steel Armor has more solder points on the PCB for more strength and protects the PCI-Express signals against electromagnetic interference for a stutter-free user experience.

Connections at your Fingertips

Experience Next Gen Networking

WI-FI 6 & BLUETOOTH 5.1MSI B550M Mortar now features Wi-Fi 6 adopting the latest OFDMA and two-way MU-MIMO technologies. Which could provide up to 4X network capacity and efficiency in a high signal density environment. When comparing this to Wi-Fi 5, which can only send a data packet to one device at a time on each channel, Wi-Fi 6 can combine the packet sending it to several devices and allow signals from the different devices to be bundled together. This new technology gives all of the devices in the same network the traffic bandwidth in a far more effective and efficient manner.

Professional Gaming Audio

AMPLIFY YOUR GAME WITH AUDIO BOOSTMSI Audio Boost delivers the highest sound quality through the use of premium quality audio components. This lets you enjoy breathtaking, game-changing sound to create the most dynamic soundscapes dedicated to giving gamers true Hi-Fi sound offering a clear advantage over your opponents when gaming. Audio Boost offers a HD audio processor, dedicated amplifier and high quality audio capacitors, all physically isolated from the rest of the motherboard circuitry to ensure the purest audio signal to locate enemies with pin-point accuracy.
