Gigabyte B660M DS3H AX DDR4 Motherboard, Intel Socket 1700, 12/13th Gen, Micro ATX, 3 x PCIe 4.0 M.2, 2.5GbE LAN, 802.11ax WiFi 6, USB 3.2 Gen 2 Type-C, RGB FUSION 2.0, Q-Flash Plus

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

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.

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.

GIGABYTE Ultra-Efficient M.2 Thermal Guard
With durability in mind, GIGABYTE provides a thermal solution for M.2 SSD devices. The M.2 Thermal Guard prevents throttling and bottlenecks from high speed M.2 SSDs as it helps to dissipate heat before it becomes an issue.

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.
