Gigabyte B650 UD AX AM5 ATX Motherboard

Digital VRM Design

This VRM design comes with high quality components.

• 6+2+2 Phases digital PWM + Low RDS(on) MOSFETs
• Supports the latest CPUs and delivers enhanced system performance and ultimate hardware scalability

EXPO & XMP Support

DDR5 EXPO & XMP overclocking up to 8000 MHz and beyond.

Shielded Memory Routing

All memory routing is under the PCB inner layer shielded by a large ground layer to protect from external interference.

Unlock DDR5 Voltage

Gigabyte-exclusive DDR5 Circuit Design increases DDR5 memory overclocking performance and capability by transforming native DDR5 memory module to overclocked DDR5 memory.

Secure Mode

The motherboard provides fixed 5V to native DDR5 memory and built-in PMIC outputs locked 1.1V to memory IC.

• Unlocks Native DDR5 PMIC secure mode into programmable mode and controls Native DDR5 voltage with wide range.
• Supports all PMIC vendors for maximum compatibility.

Maximum Compatibility for Memory Overclocking

This Gigabyte AM5 motherboard supports both AMD EXPO and Intel XMP overclocking memory modules for maximal compatibility. The motherboard will automatically detect both profile formats in SPD, so users can enable one of profiles from the BIOS menu and easily reach overclocked memory performance.

DDR5 Auto Booster

Automatically boost the native DDR5 frequency to 5000 MHz while the system is under heavy loading by a single click.

AMD EXPO and Intel XMP 3.0 User Profile

Easily create overclocked memory performance by defining and creating your own SPD profile into Native and XMP 3.0 memory modules, or by applying the pre-tuned profiles to XMP 3.0 User Profile.

• Performance Simulation - based on user input clock and timing parameters.
• User-defined profile can be saved and cleared, loaded either locally or from/to an external storage device, carried to the next computer, or share your memory parameters online.

Future Connectivity

The ultimate connectivity with blazing data-transfer speeds through the next generation network and storage.

Wi-Fi 6 (802.11ax)

Wi-Fi 6 (802.11ax) enables Gigabit-class wireless performance, provides smooth video streaming, a better gaming experience, fewer dropped connections, and speeds up to 2.4 Gb/s. Moreover, Bluetooth 5.3 provides 4x the range over Bluetooth 4.2 and with faster transmission speeds.

GbE LAN with Bandwidth Management

Helps to improve network latency and maintain low ping times to deliver better responsiveness in crowded LAN environments.

PCIe 4.0 Hardware Design

Featuring one PCIe 4.0 x16 slot and PCIe 4.0 M.2 slot support, Gigabyte motherboards are ready to work with PCIe 4.0 devices to provide superior performance.

High-End Audio Capacitors

These high quality capacitors help deliver high resolution and high fidelity audio to provide the most realistic sound effects.

Audio Noise Guard

Essentially separates the board's sensitive analog audio components from potential noise pollution at the PCB level.

EZ-Latch

Unlock the latch of the PCIe slot easily when removing the graphics card in the PCIe slot.

Q-Flash Plus

Update the BIOS easily without installing the CPU, memory, and graphics card.

• Step 1: Plug the 24-pin and 8-pin power supply cables into the motherboard.
• Step 2: Download the motherboard BIOS file and rename it to "gigabyte.bin". Save it to a USB flash drive formatted in FAT32. Insert the USB flash drive into the Q-FLASH PLUS USB port.
• Step 3: Press the Q-FLASH PLUS button, and the motherboard will start updating the BIOS automatically.

Smart Fan 6

Ensures optimal cooling and quiet operation for your gaming PC, with support for PWM/DC fans and pumps, customizable settings, and intuitive temperature monitoring.

• High Current Support: Each fan header supports PWM and DC fan and Water Cooling Pump, and up to 24W (12V x 2A) with Over-Current Protection.
• Precision Control: Multiple temperature/fan speed control points for precise fan curve.
• Dual Curve Mode: Slope/Stair dual mode for different user scenario.
• Fan Stop: Fan can stop completely below users' specified temperature point.

Smart Fan 6 BIOS UI

• Enhance Fan Curve UI: Enhance fan curve control with an expanded number of control points, from 5 to 7, and a larger fan speed graph, enabling users to have more precise and effortless control over fan curve settings.
• Slope/Stair Dual Graph Mode: Switch between Slope and Stair modes to adapt to various user scenarios. Slope mode provides a linear fan speed curve, while Stair mode maintains a constant fan speed within specified temperature intervals.
• Manual Input: For advanced users, manual input of fan speeds is available for fine-tuning and precise control over the cooling system.
• EZ Tuning: Simplify the process with EZ Tuning by setting 4 points on a rough temperature/fan speed scale. Smart Fan 6 will quickly generate a fan curve based on these points.
• Fan Curve Profile: Save your customized fan curve profile in the BIOS ROM, ensuring it remains intact even after BIOS updates.

UC BIOS

• Enhanced Intuitive UX - Gigabyte User-Centred (UC) BIOS has enhanced the BIOS UX to provide users with an optimized experience featuring an intuitive operation interface and an aesthetically pleasing design.
• Quick Access Function - Gigabyte UC BIOS' Quick Access function selects 9 practical preset options from Advance Mode and places them in Easy Mode for effortless access without switching or searching.
• Gigabyte PerfDrive - PerfDrive technology integrates exclusive BIOS settings from GIGABYTE, enabling easy balance of performance, power consumption, and temperature with Intel Core processors.
• Max Turbo - Unleashes the maximum Turbo Boost speed of Intel Core CPUs.
• Optimization Mode - Strikes a balance between high performance and low temperature for Intel Core CPUs.
• Spec Enhance Mode - Enables high-performance operation of Intel Core CPUs at lower temperature settings.
• E-Core Disable Mode - Dedicates CPU resources exclusively to the P-core, enhancing gaming performance while reducing overall power consumption.
