2. PCIe 4.0 Ready PCB
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.
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.
Please see the complete validated memory support list. Product features may vary by model.

First adopter on 2.5 GbE LAN onboard

2X Faster than ever
  1. Adoption of 2.5G LAN provide up to 2.5 GbE network connectivity, with at least 2 times faster transfer speeds compared to general 1 GbE networking, perfectly designed for gamers with ultimate online gaming experience.

  2. Support Multi-Gig(10/100/1000/2500Mbps) RJ-45 Ethernet


WIFI 6 802.11ax + BT 5 Module
Wireless solution supports 802.11ax, enables gigabit wireless performance, provides smooth video streaming, better gaming experience, few dropped connections and speeds up to 2.4Gbps*. Moreover, Bluetooth 5 provides 4X range over BT 4.2 and with faster transmission.
Benefit of WIFI 6
  1. 5.5X throughput than 802.11ac 1x1*
  2. 4X better network capacity, no traffic jams especially in those dense area with lots of devices
  3. Network efficiency increase for better user experience
Connecting the Future - USB Type-C®
The World's Next Universal Connector
The USB Type-C® is a new reversible connector that is loaded with useful features such as USB 3.2 Gen2 support for 10Gb/s transfer speed. Powered by the Intel® USB 3.2 Gen2 controller, this little port provides the best USB Type-C® experience possible.
HDMI 2.0 for 4K UHD Display and HDCP 2.2 supported
HDMI 2.0, which is backwards compatible with HDMI 1.4, offers 18 Gb/s of bandwidth – nearly twice that of the 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), offering the best visual experience for viewers.
High-End Audio Capacitors
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.
Audio Noise Guard
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.
