Features


Performance

Gigabyte B660M Gaming AC D4 Motherboard Feature 1

Hybrid Digital VRM Design - 6+2+1 Phases Hybrid Power Design

Cleaner and more efficient power delivery to the CPU with better thermal performance ensure stability under high CPU frequencies and heavy loading.

  • 6+2+1 Phases Low RDS(on) MOSFETs
  • Solid capacitors to improve transient response and minimize oscillation
  • 8-pin Solid Pin CPU Power Connector

PCIe 4.0 Design

GIGABYTE B660 Motherboards are ready to work with the PCIe 4.0 devices which are expected to experience twice bandwidth than the current PCIe 3.0 devices. To reach the high speed and maintain good signal integrity, GIGABYTE R&D uses the low impedance PCB to provide the maximum performance.

  • PCIe 4.0 x16 slot
  • PCIe 4.0 M.2 Connector
  • PCIe 4.0 Ready PCB

Support for DDR4 XMP Up to 5333MHz and Beyond*

GIGABYTE is offering a tested and proven platform that ensures proper compatibility with profiles up to 5333MHz and beyond. All users need to do to attain this performance boost is to ensure that their memory module is XMP capable and that the XMP function is activated and enabled on their GIGABYTE motherboard.

* XMP Profile support may vary depending on memory module.

Smart Fan 6

Smart Fan 6 contains several unique cooling features that ensure gaming PC maintain its performance while staying cool and quiet. Multiple fan headers can support PWM/DC fan and pump, and users can easily define each fan curve based on different temperature sensors across the board via intuitive user interface.

Headers & Sensors

  • 4 PWM/DC Fan Headers
  • 6 Internal Temperature Sensors

Cooling Features

  • High Current Support - Each fan headers support PWM and DC fan and Water cooling Pump , and up to 24W (12V x 2A) with Over-Current Protection
  • Precision Control - Up to 6 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

  • Improve fan curve UI
    We increase control points from 5 to 7 and larger fan speed graph for precise and easier fan curve control.
  • Slope/Stair dual graph mode
    Fan curve can be quickly switch with Slope and Stair modes for different user scenario. Slope is traditional and intuitive linear fan speed curve. With newly added Stair non-linear mode, fan keeps at same speed between specified temperature interval.
  • Manual Input
    For advanced users, we provide fan speed manual input for more precise control.
  • EZ Tuning
    Use can place 4 EZ Tuning points at rough temperature/fan speed, and Smart Fan 6 can quickly generate a fan curve.
  • Fan curve profile
    Fan curve profile can be saved in BIOS ROM, profile will be kept after updating BIOS.

Fan Stop

Achieve fan silence. With Fan Stop, map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperature—all of it can be customized to your liking.

Hybrid Cores Optimization

With new Intel Hybrid technology, GIGABYTE exclusively creates two new " CPU Upgrade " in BIOS profiles to meet different users’ scenarios by adjusting P-Core and E-Core activation and voltage policy.

Gaming

  • Deactivate all E-Core
  • Zero compromise on gaming performance
