F2A55-M LE AMD A55 Chipset (Socket FM2) DDR3 Micro ATX Motherboard

AMD® A-series Accelerated Processor with AMD Radeon™ HD 7000 Series Graphics: This motherboard supports AMD® A-series Accelerated Processor with AMD Radeon™ HD 7000 Series Graphics. This revolutionary APU (Accelerated Processing Unit) combines processing power and advanced DirectX 11 graphics in one small, energy-efficient design to enable accelerated performance and an industry-leading visual experience. It features Dual-channel DDR3 memory support and accelerates data transfer rate up to 5GT/s.

• DIGI+ VRM - Digital Power Design for the APU • AI Suite II - One stop Access to Innovative ASUS Features
• Network iControl - Real-time Network Bandwidth Control
• UEFI BIOS - Flexible & Easy BIOS Interface

AMD® A55 FCH(Hudson D2): AMD® A55 FCH (Hudson D2) is designed to support up to 5GT/s interface speed and 6 x SATA 3.0Gb/s

Quad-GPU CrossFireX Support! Flexible Multi-GPU solutions, Your Weapon of Choice!
F2A55 brings you the multi-GPU choice of CrossFireX™. Expect a brand-new gaming style you’ve never experienced before!

DIGI+ VRM: DIGI+ POWER CONTROL: Digital Power Design for the APU ASUS motherboards using the AMD® A55 chipset employ precise digital voltage regulation for the APU, called DIGI+ VRM (Voltage Regulation Modules) digital power design. The APU voltage is adjusted via either carefully developed automated modes, or by using user-defined profiles. The effect is that DIGI+ VRM technology ensures greater energy efficiency and the most precise power delivery. Boosted by world-renowned ASUS quality, it creates an ideal computing platform for a diverse range of applications, from gaming to multimedia or office work and heavy multitasking. Engineered and tested to assure unmitigated performance, ASUS A55 boards with DIGI+ VRM remain efficient and accurate, for reliable application in every scenario.

* DIGI+ VRM functions also available in FM2 socket compatible CPUs.

TurboV: Easy, Real-Time O.C. Tunings Feel the adrenaline rush of real-time OC-now a reality with the ASUS TurboV. This easy OC tool allows you to overclock without exiting or rebooting the OS; and its user-friendly interface makes overclock with just a few clicks away. Moreover, the ASUS OC profiles in TurboV provides the best O.C. settings in different scenarios.

USB 3.0 Boost: Faster USB 3.0 Transmission with UASP ASUS USB 3.0 Boost technology supports UASP (USB Attached SCSI Protocol), the latest USB 3.0 standard. With USB 3.0 Boost technology, a USB device's transmission speed is significantly increased up to 170%, adding to an already impressive fast USB 3.0 transfer speed. ASUS software automatically accelerates data speeds for compatible USB 3.0 peripherals without the need for any user interaction.

Network iControl: Real-time Network Bandwidth Control With a single-click on/off button, the application currently in use has its data and network bandwidth prioritized over other programs. Moreover, you can prioritize your favorite software easily by configuring profiles through the intuitive user interface. Within the profile, programs can be pre-scheduled to run in a specific time period to avoid network congestion and long-waits on downloads. Auto PPPoE network connection provides a one-step setup for enhanced online convenience. Overall, it's an intuitive network bandwidth control center.

AI Suite II: One stop Access to Innovative ASUS Features
With its user-friendly interface, ASUS AI Suite II consolidates all the exclusive ASUS features into one simple to use software package. It allows users to supervise Overclocking, energy management, fan speed control, voltage and sensor readings. This all-in-one software offers diverse and ease to use functions, with no need to switch back and forth between different utilities.

UEFI BIOS (EZ mode): ASUS UEFI BIOS offers the first mouse-controlled graphical BIOS designed with selectable modes, providing a user-friendly interface that goes beyond traditional keyboard-only controls. It also natively supports fully-utilized hard drives larger than 2.2TB in 64-bit operating systems.
ASUS Exclusive Interface EZ Mode displays frequently-accessed info. Users can choose system performance settings and drag and drop boot priorities. Advanced Mode for performance enthusiasts includes detailed DRAM settings via a dedicated memory info page for complete insight.
