Asus P9X79 WS - Manual (Page 22)

1-4 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.
1.3.3 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.
