1-3

The world’s first Dual Intelligent Processors from ASUS pioneered twin onboard chips 
- TPU (TurboV Processing Unit) and EPU (Energy Processing Unit). Third generation 
Dual Intelligent Processors with New DIGI+ Power Control include two digital voltage 
regulator modules (VRMs). An all-new digital controller now allows ultra-precise DRAM 
tuning in addition to CPU voltage control. 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 

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.

Unleash your performance with ASUS’ simple onboard switch or 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.

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 convenicnce and seamless transition offered by complete backward 
compatibility with PCIe 1.0 and PCIe 2.0 devices. It is a must-have feature PC users aiming 
to improve and optimize graphics performance, as well as have the latest, most future-proof 
technology.
