Chapter 1: Product Introduction

Diag. LED

Diag. LED checks key components (CPU, memory, graphics card and hard drive)

in sequence during bootup. If an error is found, the LED next to the

relevant

device will stay lit until the problem is solved. This user-friendly design provides an

intuitive way to locate root problems in seconds.

Quick Gate

Quick Gate is a vertical USB connector on the motherboard, allowing

you to install

USB devices directly with no messy cables. This stops important data storage

devices from breaking off unexpectedly. P9X79 WS with this unique design

provides a convenient and safe way to install data and applications on your PC.

ASUS features

New DIGI+ Power Control

All-New Digital Power Control for both CPU and DRAM

ASUS X79 motherboards include New DIGI+ Power Control with two digital voltage

regulator modules (VRMs), including an all-new DRAM controller that allows

ultra-precise memory tuning in addition to CPU voltage control. This evolution of

innovative, industry-leading ASUS technology provides super-accurate voltages 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

imprecision, and provides more stable CPU Vcore voltages.

Increased CPU and DRAM overclocking range

With programmable digital controllers onboard, users can adjust CPU and

DRAM PWM voltages and frequencies for various overclocking scenarios, with

accurate input through UEFI BIOS tuning or the exclusive ASUS interface. System

performance can also be customized with speciﬁc CPU and DRAM power controls,

including new VCCSA load line calibration for increased voltage range, greater

VCCSA current capability, and up to 30% more capacitance. This proprietary

design, with its precise yet ﬂexible power adjustments, increases overclocking

headroom to push performance to its full potential.
