New DIGI+ Power Control

New DIGI+ Power Control

All-New Digital Power Control for both CPU and DRAM

ASUS X79 motherboards include New DIGI+ Power Control with three digital voltage controllers, 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.

Best in class power efficiency and stability

Two critical components work perfectly together to match

digital power signal (SVID) requests from the CPU, with

ultra-fast sensing and response to efficiently deliver the

right level of power on demand. Accurate power reduces

wasteful voltage imprecision, and provides more a stable

CPU and memory setup.

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 VCCSA load line calibration and

30% more DRAM current capacity. Dual digital voltage

controllers provide two separate outputs for AB and CD

memory channels respectively. 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.

* VCCSA (system agent voltage) relates to the CPU DRAM controller. ASUS power control now provides more VCCSA options to facil itate

extreme DRAM overclocking.

Support for up to 64GB of system memory with an 8-DIMM design on ASUS X79 motherboards provides the

capacity for users to make full use of modern 64-bit software, ideal for rendering detailed images or

manipulating large files without the bottlenecks of conventional storage. It also allows users to set up big

RAM disks and speed up frequently accessed programs, minimizing the impact of storage transfer delays

while maximizing user benefit.

ASUS Exclusive Features

ASUS SSD Caching

3X faster performance at a click

SSD Caching from ASUS is easier than ever. At 3X faster, this feature boosts system

performance by using an installed SSD with no capacity limitations as a cache for

frequently accessed data. Harness a combination of SSD-like performance and

response and hard drive capacity with just one click, no rebooting needed and instant

activation for complete ease of use, and even prevent data loss with included backup

functionality.

UEFI BIOS

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.

USB BIOS Flashback

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! > Learn More
