The P9X79 WS provides complete compatibility with RAID and LAN cards.Users enjoy a wider selection of devices and higher reliability. As a workstation motherboard that puts an emphasis on system integration, the P9X79 WS offers the benefit of greater confidence and convenience.

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.

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 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!

Fan Xpert+

Customizable speeds with independent fan control
Hardware-level ASUS Fan Xpert+ allows users to independently adjust both CPU and case fan speeds with multiple dedicated controllers based on different ambient temperatures, climate conditions and system loads. Built-in profiles offer flexible automatic and manual fan speed controls to achieve a quiet and cool computing environment.

PCIe 3.0 Ready
The latest PCI Express bus standard delivers improved encoding for twice the performance of current PCIe 2.0. Total bandwidth for a x16 link reaches a maximum of 32GB/s, double the 16GB/s of PCIe 2.0 (in x16 mode). PCIe 3.0 provides users unprecedented data speeds, combined with the convenience and seamless transition offered by complete backward compatibility with PCIe 1.0 and PCIe 2.0 devices. It’s a must-have feature for PC users aiming to improve and optimize graphics performance, as well as have the latest, most future-proof technology.
