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.

XTREME MEMORY
GIGABYTE B660 Motherboards feature the latest DDR5 architecture and XMP 3.0 capability. The new DDR5 memory technology brings 50% more bandwidth to the platform and increases the system performance drastically by implementing Unlocked Native DDR5 Voltage, Xtreme Memory Routing and reliable SMD slot. In addition to the hardware upgrades, the user friendly UI provides full functionality to overclock higher with exclusive DDR5 tuning capability.

DDR5 Comes with 50% Performance Increase
DDR5 delivers 50% improvement compared to last generation. DDR5 massively elevates the system level performance. DDR5 provides more bandwidth to keep up with the higher CPU core count bandwidth requirement. The new memory architecture also reduces the power consumption.

Support for DDR5 XMP Up to 5600MHz and Beyond*
GIGABYTE is offering a tested and proven platform that ensures proper compatibility with profiles up to 5600MHz 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.

Fan Stop
Fan can stop completely below users' specified temperature point

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.
