Gigabyte B550M DS3H AC R2 mATX Motherboard
5+3 Phases Pure Digital VRM Solution with Low RDS(on) MOSFETs
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.
Benefits of Low RDS(on) MOSFETs
- Optimized gate charge to minimize switching losses
- Lower temperature, smaller size, better thermal characteristics
PCIe 4.0* Hardware Design
- PCIe 4.0 Slot: PCIe 4.0 x16 slot with faster bandwidth and lower impedance
- M.2 PCIe 4.0 Slot: M.2 PCIe 4.0 x4 slot with lower impedance
Faster and Better Coverage with Intel Dual Band 802.11ac WIFI + BT 4.2 Module
The onboard 802.11ac WIFI module from Intel® supports Dual Band and up to 433 Mbps, 3x faster WIFI speed than 802.11n and also supports 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 onboard, GIGABYTE Motherboards allow users to experience NVMe or SATA mode connectivity for M.2 SSDs. With up to 64 Gb/s transfer speed, this dual M.2 design supports RAID configurations for ideal storage solutions.
Realtek GbE LAN with Bandwidth Management
Realtek Gigabit LAN includes a bandwidth management app that improves latency and maintains low ping times in busy LAN environments.
HDMI 2.1 for 4K / 60P / 21:9 / HDCP 2.3 Support
HDMI 2.1 provides up to 48 Gb/s bandwidth—double that of the previous generation—supporting multiple video streams, 21:9 cinematic ratios, Full HDR, and HDCP 2.3 compatibility.
Note: Only New Gen AMD Ryzen™ with Radeon™ Graphics processors support display output.
SMART FAN 6
Smart Fan 6 provides advanced cooling features to keep your system cool and quiet:
- High Current Support: Up to 24W (12V x 2A) with PWM/DC fan and pump headers
- Precision Control: Multiple temperature/fan speed points for accurate fan curves
- Dual Curve Mode: Choose between Slope and Stair fan response modes
- Fan Stop: Fans stop when temperatures fall below set thresholds
Smart Fan 6 BIOS UI Features
- Increased control points from 5 to 7 and larger graph for easier fan curve tuning
- Slope/Stair dual graph mode for intuitive and non-linear control
- Manual fan speed input for precise configuration
- EZ Tuning points generate a fan curve quickly
- Fan curve profiles saved in BIOS ROM, retained after updates
RGB FUSION 2.0
RGB Fusion 2.0 supports Addressable LED lighting with enhanced customization:
- Control onboard and external RGB/Addressable LED strips (up to 300 LEDs)
- Multiple colors, patterns, and speed settings
RGB Fusion 2.0 Software & App
The integrated RGB Fusion 2.0 interface offers full lighting control across motherboards, GPUs, and peripherals. Personalize your setup and sync effects with supported games for an immersive experience.
