Unleash the full power of your Intel 12th Gen system with the B660 AORUS Master DDR4 LGA 1700 ATX Motherboard from GIGABYTE. Featuring the B660 chipset, supporting 12th generation Intel processors with the LGA 1700 socket, this ATX motherboard is designed to support high-performance computer builds for gaming and content creation. The B660 AORUS Master DDR4 takes full advantage of the large PCIe 4.0 data bandwidth to maximize speeds with compatible devices, including four memory slots that support up to 128GB of dual-channel DDR4 memory, reaching 5333 MHz when overclocked with XMP. It also includes slots for up to four SATA III drives and three M.2 PCIe 4.0 and 3.0 SSDs, which can be put into RAID 0, 1, 5, or 10 configuration and enhanced with Intel Optane technology. Additionally, its three expansion slots can accommodate two PCIe 4.0 x16 devices, including support for AMD cross-fire dual GPU setups. Compatible expansion cards can additionally be installed into the PCIe 3.0 x16 slot.

Peripherals such as mice and keyboards can be connected to the USB 2.0 ports while reserving the USB 3.2 Gen 2x2 Type-C and USB 3.2 Gen 2 Type-A and Type-C ports for 20 Gb/s and 10 Gb/s compatible devices. The Realtek ALC1220-VB 7.1-channel audio codec provides rich sound and provides a line out audio jack that supports DSD audio. The RGB lighting headers allow you to customize RGB Fusion compatible light strips and devices with multiple colored effects. A 2.5G Ethernet port and integrated Wi-Fi 6 support provide high-speed data transfers with compatible networks and devices for low-latency online gaming experiences and smooth 4K video streaming. Windows 10 64-bit is the supported operating system to take full advantage of this motherboard's features. 

Intel B660 Express Chipset

Utilizing the LGA 1700 socket and B660 chipset, this motherboard is compatible with 12th Gen Intel Core, Pentium, Gold, and Celeron processors.

Performance Features

Power Design

Designed to ensure optimal performance with Intel 12th Gen processors, the B660 AORUS MASTER uses a twin hybrid VRM layout designed to unleash the full power of your CPU. Multi-core CPU performance uses 16VCORE twin phases with a 60A DrMOS to stabilize power, one VCCGT phase with 50A power stage for integrated graphics, and one VCCAUX phase to provide stable power for CPU integrated PCIe and memory controllers. Additionally, with new Intel Hybrid Technology, GIGABYTE exclusively created two new "CPU Upgrade" in BIOS profiles to meet different users' scenarios by adjusting P-Core and E-Core activation and voltage policy.

DDR4 XMP Memory

AORUS is offering a tested and proven platform that ensures proper compatibility with profiles up to 5333 MHz 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 on the B660 AORUS MASTER motherboard.

All memory routing is under the PCB inner layer shielded by a large ground layer which protects from external interference and provides protection to your memory modules. 

The maximum memory capacity on the B660 AORUS MASTER is 128GB. After Intel updated the memory reference code, a single slot can support up to 32GB. Populated with 2 DIMMs per channel on both channels, the total memory capacity is 128GB, which was only previously available on High End Desktop (HEDT) platforms. For users who always run out of memory capacity, there is more bandwidth now for memory-intensive application such as rendering and video editing. 

Triple PCIe 4.0/3.0 x4 M.2 Connectors with Thermal Guard

The B660 AORUS MASTER is focused on delivering M.2 technology to enthusiasts who want to maximize their systems' potential. The PCIe 4.0 x4 M.2 slot supports up to 64 Gb/s bandwidth while the 2nd Gen PCIe 4.0 SSD supports NVMe SSD read speeds up to 7000 Mb/s.

Solid Pin Power Connectors

Solid plated ATX 12V 8-pin + 4-pin power connectors supply stable power during CPU overloading.

Thermal Features

Fully Covered MOSFET Heatsink

Featuring an increased surface area up to 2X larger when compared to traditional heatsinks, the MOSFET heatsink improves heat dissipation from the MOSFETs. The one-piece TMOS heatsink has a larger surface area that improves the cooling performance when compared to multi-piece heatsinks. Multiple channels and inlets on the heatsink allow air to flow through it for more efficient heat transfer

M.2 Thermal Guard

Designed with durability in mind, 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.

2X Copper PCB

By adopting 2X copper on the PCB inner layer, the component's temperature is lowered at least by 3% by turning the PCB into a super-thin PCB size copper heatsink to dissipate the heat from the components effectively, due to its high thermal conductivity and lower impedance.

Smart Fan 6

Smart Fan 6 contains several cooling features that ensure gaming PCs maintain their 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. Each fan header supports PWM and DC fan and Water cooling pumps, and up to 24W (12V x 2A) with Over-Current Protection. 

Featuring the Smart Fan 6 BIOS UI, fan curve can be quickly switched with Slope and Stair modes for different user scenarios. Slope is a traditional and intuitive linear fan speed curve, while with the newly added Stair non-linear mode, the fans maintain the same speed between specified temperature intervals. For advanced users, there is manual fan speed input for more precise control of the fans. 

With EZ Tuning, users can place 4 EZ Tuning points at rough temperature/fan speed intervals, and Smart Fan 6 will quickly generate a fan curve. Fan curve profiles can be saved in the BIOS ROM, and the profile will be kept after updating the BIOS.

Featuring an Intelligent Fan Control Design, users can achieve fan silence. Map any fan to stop completely when temperatures drop below a specified threshold, and control which fan stops and at what temperature based on readings from specific sensors.

Connectivity Features

Intel 2.5GbE Lan

With the adoption of 2.5G LAN, users are provided with up to 2.5 GbE network connectivity speeds, with at least 2X faster transfer speeds when compared to general 1GbE networking, designed with gamers in mind who are looking for the ultimate online gaming experience.

Wi-Fi 6 802.11ax

802.11ax Wi-Fi 6 features a new dedicated 6 GHz band that enables gigabit wireless performance and provides smooth video streaming and a better gaming experience with fewer dropped connections and speeds up to 2.4 Gb/s. Additionally, Bluetooth 5 provides 4X range over BT 4.2 with faster data transmission.

USB 3.2 Gen 2x2 Type-C

Featuring the USB 3.2 Gen 2x2 design which is doubled the performance than the previous generation of USB 3.2 Gen 2. It works up to 20 Gb/s data transfer while connecting to USB 3.2 compliant peripherals. Through the USB Type-C connector, users can enjoy the flexibility of reversible connection to access and store massive amounts of data rapidly.

Personalization Features

RGB Fusion

With full RGB support and a redesigned RGB Fusion 2.0 application, users now have complete control over the LEDs which surround the motherboard.

UEFI BIOS

The B660 AORUS MASTER introduces an EASY MODE to the UEFI BIOS which shows hardware information all on one page, including CPU clock, memory, storage, and fan information. Users can add constantly used items into the favorite menu for quick access, while the Storage Information page shows all information related to SATA, PCIe, and M.2 interfaces. The changelog lists all changes so that you can save and review overall setting modifications, while the intuitive load line curve clearly shows each loadline calibration setting in a curve graph.

EasyTune

GIGABYTE's EasyTune is an interface that allows users to fine-tune their system settings or adjust system and memory clocks and voltages in a Windows graphical 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

The 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.

Q-Flash Plus

With the GIGABYTE Q-Flash Plus, you don't need to install the CPU, memory, and graphics card to flash the BIOS. Just download and save a new BIOS file on the included USB flash drive, then press the dedicated Q-Flash Plus button and you're good to go.
