GIGABYTE B550M DS3H AC (rev. 1.5/1.6) AMD B550 Socket AM4 micro ATX

<b>AMD StoreMI Technology</b>GIGABYTE B550 motherboards maximize your PC's potential with AMD StoreMI technology. StoreMI accelerates traditional storage devices to reduce boot times and enhance the overall user experience. This easy-to-use utility combines the speed of SSDs with the high capacity of HDDs into a single drive, enhances the read/write speeds of the device to match that of SSDs, bolsters data performance for incredible value, and transforms the everyday PC to a performance driven system.<b>The benefits of AMD StoreMI:</b>• Making the PC experience fast, smooth and easy• Optimizing computer responsiveness from system boot to application launch• Offering SSD performance with HDD capacity at an affordable cost• Quickly accessing key files by automatically learning users' computing behaviors<b>PERFORMANCE</b>GIGABYTE UD series motherboards use a 5+3 phases pure digital PWM + Low RDS(on) MOSFETs design to support the 3rd Gen AMD Ryzen CPUs by offering incredible precision in delivering power to the motherboard's most power-hungry and energy-sensitive components as well as delivering enhanced system performance and ultimate hardware scalability.<b>Benefits of Low RDS(on) MOSFETs</b>‧ Optimized gate charge to minimize switching losses.‧ Lower temperature, smaller size, better thermal characteristics.<b>1.PCIe 4.0 Slot</b>PCIe 4.0 x16 slot with faster bandwidth and lower impedance.<b>2.M.2 PCIe 4.0 Slot</b>M.2 PCIe 4.0 x4 slot with Lower impedance.<b>Faster and Better Coverage with Dual Band 802.11ac WIFI + BT Support Module</b>The onboard 802.11ac WIFI module supports Dual Band and up to 433 Mbps, 3x faster WIFI speed than 802.11n and also support BLUETOOTH features.<b>Dual NVMe PCIe 4.0/3.0 M.2 Connectors</b>With dual NVMe PCIe 4.0*/3.0 M.2 connectors onboard, GIGABYTE Motherboards bring users to experience NVMe mode or SATA mode connectivity for M.2 SSD devices. Delivering up to 64 Gb/s data transfer speed, the dual M.2 connectors design provides an ideal storage solution while also supporting in RAID modes.<b>Realtek GbE LAN with Bandwidth Management</b>Realtek Gigabit LAN features a network bandwidth management application which helps to improve network latency and maintain low ping times to deliver better responsiveness in crowded LAN environments.<b>HDMI 2.1 for 4K / 60P / 21:9 / HDCP 2.3 Support</b>HDMI 2.1, which is backwards compatible with HDMI 2.0/ 1.4 and offering 48 Gb/s of bandwidth – twice times more than previous generation. This unlocks the potential for users to transfer multiple video streams, as well as a native cinematic 21:9 ratio (which most movies are shot in), Full HDR and HDCP 2.3 support, to offer the best visual experience for viewers.<b>Smart Fan 5</b>With Smart Fan 5 users can ensure that their gaming PC can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard. Not only that, with Smart Fan 5 more hybrid fan headers that support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid cooling friendly.<b>High-End Audio Capacitors</b>GIGABYTE motherboards use high-end audio capacitors. These high quality capacitors help deliver high resolution and high fidelity audio to provide the most realistic sound effects for gamers.<b>Audio Noise Guard</b>GIGABYTE motherboards feature an audio noise guard that essentially separates the board’s sensitive analog audio components from potential noise pollution at the PCB level.<b>Solid Pin Power Connectors</b>B550 motherboards feature solid plated ATX 12V 8pin power connectors for offering stable power supply while CPU overloading.<b>START SULFURIZATION PROTECTION</b>Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an Anti-Sulfur Design GIGABYTE gives Ultra Durable Motherboards a whole new meaning.<b>Refreshed BIOS</b>The BIOS is essential for users during initial setup to allow for the most optimal settings. With a new GUI and easier to use functionalities, GIGABYTE has been able to reinvent the BIOS to give users a better experience while setting up their new system.Gigabyte B550M DS3H AC (rev. 1.5/1.6).
