Chapter 1
1.3.2 Dual Intelligent Processors 3 with New DIGI+ Power Control
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.
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.
TPU
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.
EPU
Tap into the world’s first real-time PC power saving chip through a simple onboard switch or
AI Suite II utility. Get total system-wide energy optimization by automatically detecting current
PC loadings and intelligently moderating power consumption. This also reduces fan noise
and extends component longevity.
