ABOUT Gigabyte B550M DS3H AC Micro ATX Motherboard
AMD StoreMI Technology – Gigabyte B550M DS3H AC Micro ATX Motherboard Maximizes 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 an SSD with the high capacity of an HDD in a single drive, increasing device read/write speeds to match SSDs, boosting data performance to an incredible standard, and transforming everyday PCs. In performance-driven systems.
The benefits of AMD StoreMI –
- Making the PC experience faster, smoother, and easier.
- Optimizing computer responsiveness from system boot to application launch.
- Offering SSD performance with HDD capacity at an affordable cost.
- Quickly access key files by automatically learning users’ computing behavior.
5+3 Phases Pure Digital VRM Solution with Low RDS(on) MOSFETs – Gigabyte UD Series motherboards use a 5+3 Phase Pure Digital PWM + Low RDS(on) MOSFETs design to support 3rd Gen AMD Ryzen CPUs, delivering incredible precision in delivering power to the most power-hungry and power-sensitive components on the motherboard. . As well as providing improved system performance and ultimate hardware scalability.
Benefits of Low RDS(on) MOSFETs –
- Optimized gate charge to reduce switching losses.
- Low temperature, small size, good thermal properties.
Fast and good coverage with Intel Dual Band 802.11ac WIFI + BT 4.2 Module – Intel’s onboard 802.11ac WIFI module supports dual band and up to 433 Mbps, 3x faster WiFi speed than 802.11n, and Bluetooth 4.2.
Dual NVMe PCIe 4.0/3.0 M.2 Connectors – With NVMe PCIe 4.0/3.0 x4 and PCIe 3.0 x2 M.2 connectors, GIGABYTE motherboards bring users NVMe mode or SATA mode connection experience for M.2 SSD devices. Providing data transfer speeds of up to 64 Gb/s, the dual M.2 connector design provides an ideal storage solution and also supports RAID mode.
Realtek GbE LAN with bandwidth management – Realtek Gigabit LAN includes a network bandwidth management application that helps maintain low ping times to improve network latency and provide better responsiveness in congested LAN environments.
HDMI 2.1 for 4K / 60P / 21:9 / HDCP 2.3 Support – HDMI 2.1, which is backward compatible with HDMI 2.0/ 1.4 and offers 48 Gb/s bandwidth – double that of the previous generation. It opens up the possibility for users to transfer multiple video streams, as well as a native cinematic 21:9 ratio (where most movies are shot), full HDR, and HDCP 2.3 support, to provide the best visual experience for viewers.
Smart Fan 5 – Smart Fan 5 users can confirm that their gaming PC can maintain its performance while staying cool. Smart Fan 5 allows users to change their fan headers to reflect additional thermal sensors at different locations on the motherboard. Not only that, but also 5 hybrid fan headers with smart fans that support both PWM and Voltage mode fans to make the motherboard better liquid cooling friendly.
Fan Stop – Devotees achieve silence. With Fan Stop, map any fan to stop completely when the temperature drops below a certain point. Which fan stops, based on readings from which sensors, and at what temperature—all can be customized to your liking.
Hybrid Fan Pin Headers – Assume full control over your liquid cooling setup! Smart Fan 5 receives up-to-the-second information on flow rate and water temperature via the hybrid fan pin header or external thermistor sensor—giving you complete control over your PC.
All hybrid fan headers can automatically detect the type of cooling device whether it is a fan or a pump with different PWM or voltage modes.
New Smart Fan 5 Software –
- Choose from a variety of modes, from quiet to full speed, to match your system usage preferences
- For each fan or pump, you can use the intuitive fan curve to determine the trigger threshold and corresponding fan speed.
RGB FUSION 2.0 – With the B550 motherboard, RGB Fusion 2.0 is even better with addressable LEDs. RGB Fusion 2.0 offers users the option to control onboard RGB and external RGB / addressable LED light strips* for their PC builds. Already feature-packed with colors and patterns, RGB Fusion 2.0 has now been upgraded to improve Addressable LED support. With externally addressable LED strips, where each LED is digitally addressable users can experience more patterns, styles, and lighting.
The B550 motherboard supports external 5V addressable LED light strips and up to 300 LED lights. RGB Fusion 2.0 with addressable LEDs brings new patterns with different speed settings and more.
High-End Audio Capacitors – Gigabyte motherboards use high-end audio capacitors. These high-quality capacitors help provide high-resolution and high-fidelity audio to deliver the most realistic sound effects for gamers.
Audio Noise Guard – Gigabyte motherboards feature an Audio Noise Guard that essentially isolates the board’s sensitive analog audio components from potential noise pollution at the PCB level.
Q-Flash Plus – With GIGABYTE Q-Flash Plus, you don’t require to install CPU, memory, and graphics card or enter the BIOS menu to flash BIOS. Just download and save a new BIOS file (rename to gigabyte.bin) to a USB flash drive, then press the reserved Q-Flash Plus button and you’re good to go!
Solid Pin Power Connectors – B550 motherboard has a solid plated ATX 12V 8pin power connector to provide a stable power supply during CPU overloading.
