Third generation Dual Intelligent Processors with New DIGI+ Power Control provides a total CPU, memory and SMART DIGI+ Key profile tuning digital power solution, which includes two digital voltage controllers allowing ultra-precise DRAM tuning in addition to ultra-precise CPU voltage control - a first on the AMD platform. It's upgraded with one-click extreme performance optimization with the user-friendly AI Suite II utility. This evolution of innovative and industry-leading ASUS technology provides super-accurate voltage tuning for better efficiency, stability and performance.

All-New Digital Power Control for both CPU and DRAM
The New DIGI+ Power Control design with two digital voltage controllers upgrades motherboard power delivery to an overall solution on AMD AM3+ motherboards, including all-new DRAM controllers that offers ultra-precise memory tuning in addition to ultra-precise CPU voltage control. This evolution of innovative, industry-leading ASUS technology provides the best in class control for better efficiency, stability and performance.

TPU with the All-New SMART DIGI+ Key for a Blazing Performance Boost
Always at the forefront of power design, ASUS propels you into the future standard of power management again by giving you a complete CPU, memory and new SMART DIGI+ Technology with profile tuning digital power solution, which works with the TPU to ramp up performance to its maximum. Enable the all-new SMART DIGI+ Key profile with a single click and adjust CPU ratios manually in the TPU to increase CPU frequency up to an incredible 100%!

Increased CPU and DRAM Overclocking Range
With programmable digital controllers onboard, users can adjust CPU and DRAM voltage and VRM switching frequencies for various overclocking scenarios. New DRAM tuning possibilities make the most of DDR3 memory for better performance with CPU/NB load line calibration and 30% more DRAM current capacity. Thanks to a slew of power options teamed with an extensive and intuitive UEFI BIOS, overclocking very large memory setups is no more difficult than mainstream motherboards.

The Ultimate Turbo Processor
Unleash your performance with ASUS AI Suite II utility. The TPU chip offers precise voltage control and advanced monitoring through Auto Tuning and TurboV functions. Auto Tuning offers a user friendly way to automatically optimize the system for fast, yet stable clock speeds, while TurboV enables unlimited freedom to adjust CPU frequencies and ratios for optimized performance in diverse situations.

Energy Efficiency All Around
Tap into the world's first real-time PC power saving chip through AI Suite II utility. Get total system-wide energy optimization by automatically detecting current PC loadings and intelligently moderating power consumption. This also reduces fan noise and extends component longevity!

One-stop PC Remote Control and Home Entertainment
Remote GO! links PCs, tablets, smartphones and TVs wirelessly together through an existing LAN cable and router setup. It allows users to stream multimedia content from PC to DLNA devices, access their computer anywhere using their mobile device at home, while also allowing easy file transfers between your computer and mobile device. It provides seamless environment for a futuristic connected lifestyle with three useful functions: DLNA Media Hub, Remote Desktop and File Transfer.

Faster USB 3.0 Transmission with UASP
New 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.

Easy, Worry-free USB BIOS Flashback
USB BIOS Flashback offers the most convenient way to flash the BIOS ever! It allows overclockers to try new UEFI BIOS versions easily, without even entering their existing BIOS or operating system. It even works without key components such as the CPU and memory installed. Just plug in any USB storage and push the dedicated button for 3 seconds. The UEFI BIOS is automatically flashed using ATX standby power. Worry-free updating for the ultimate convenience!

A Dedicated Button to Access the BIOS Directly
Designed for users requiring frequent BIOS access, you can easily enter the BIOS automatically when the PC is on standby power with a press of a button. It saves you time during boot-up from having to repeatedly press the DEL key. Convenience and ease at its best!

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 favourite 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 centre.

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.

Double USB Access, Double Convenience
ASUS facilitates strategic USB 3.0 accessibility for both the front and rear panel - 4 USB 3.0 ports in total. Experience the latest plug & play connectivity at speeds up to 10 times faster than USB 2.0. This motherboard affords greater convenience to high speed connectivity.

SATA 6Gb/s Support
AMD® SB950 Southbridge natively supports next-generation Serial ATA (SATA) storage interface, this motherboard delivers up to 6 Gb/s data transfer rates. Additionally, get enhanced scalability, faster data retrieval, double the bandwidth of current bus systems.

Expand Your PC Audio Experience
To get the most out of your audio entertainment across all formats and quality levels, DTS Connect combines two enabling technologies. DTS Neo:PC™ upmixes stereo sources (CDs, MP3s, WMAs, internet radio) into as many as 7.1 channels of incredible surround sound. Consumers can then connect their PC to a home theatre system.DTS Interactive is capable of performing multi-channel encoding of DTS bitstreams on personal computers, and sending encoded bitstreams out of a digital audio connection (such as S/PDIF or HDMI) designed to deliver audio to an external decoder.

DTS UltraPC II delivers exceptional 7.1 surround through the most popular PC audio setups - your existing stereo speakers or headphones. In addition to virtual surround, it upgrades original sound to new levels with Audio Restoration, recreating the dynamic range of audio files. Symmetry mode improves the balance of perceived loudness across different input sources and Enhance boosts audio quality through high and low frequency equalization. With these technologies, users experience better home theatre audio with ease.
