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.

GIGABYTE B660 Motherboards are ready to work with the PCIe 4.0 devices which are expected to experience triple 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.

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.

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.

First adopter on 2.5 GbE LAN onboard

2X Faster than ever

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.

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

Q-Flash Plus

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

With GIGABYTE Q-Flash Plus, you don’t need to install the CPU, memory and graphics card nor enter the BIOS menu to flash the BIOS. Just download and save a new BIOS file (rename to gigabyte.bin) on the USB flash drive, then press the dedicated Q-Flash Plus button and you’re good to go!

Solid Pin Power Connectors
B660 motherboards feature solid plated ATX 12V 8pin power connectors to offer a stable power supply during CPU overloading.
Solid Pin Power connector advantages

• Larger contact area for electricity

• More metal quantity to sustain higher power and generated heat

• Ultra durable and longer lifespan

RGB FUSION 2.0

B660 motherboards feature RGB FUSION 2.0 to offer lighting effected options and customized settings with outstanding aesthetics, and able to let enthusiasts building a stylish and unique gaming PC.

* Addressable LEDs are available only on select Motherboards, external LED Strips, Addressable LED Strips are not included with Motherboard purchase.

Refreshed BIOS

The BIOS is essential for users during initial setup to allow for the most optimal settings. With a new GUI and easier to use functionalities, GIGABYTE has been able to reinvent the BIOS to give users a better experience while setting up their new system. * Photos are for reference only. Product features may vary by model.

EasyTune™

GIGABYTE's EasyTune™ is a simple and easy-to-use interface that allows users to fine-tune their system settings or adjust system and memory clocks and voltages in a Windows environment. With Smart Quick Boost, one click is all it takes to automatically overclock your system, giving an added performance boost when you need it the most.

System Information Viewer

GIGABYTE System Information Viewer is a central location that gives you access to your current system status. Monitor components such as the clocks and processor, set your preferred fan speed profile, create alerts when temperatures get too high or record your system's behavior; these are the possibilities of the System Information Viewer.
