<b>Digital Power Design: The New Standard</b>
The world’s first Dual Intelligent Processors from ASUS pioneered the use of two onboard chips - EPU (Energy Processing Unit) and TPU (TurboV Processing Unit). The new generation of Dual Intelligent Processors 2 with DIGI+ VRM provides precise Vcore PWM, integrated graphics voltages and frequency module adjustments with minimal power loss through BIOS tuning and an exclusive user interface to increase the board’s overclocking range while performance reaches its full potential. ASUS DIGI+ VRM digital power design empowers users with superior flexibility and perfect precision to ensure optimized performance, extreme system stability and greater power efficiency.
<b>DIGI+ VRM</b>
Herald the Arrival of a New Digital Power Design Era
VRM, or voltage regulator modules, are considered among the most essential motherboard design components. They supply the voltage demanded by the CPU, and a good VRM must intelligently detect actual CPU power draw to provide precise power accordingly. ASUS DIGI+ VRM features a digital programmable microprocessor onboard to perfectly match digital power signal (SVID) requests from the CPU, eliminating digital-to-analog conversion lag. The precise power delivery minimizes power transfer loss to provide highest power efficiency, greater performance, and rock solid stability with the most flexible power adjustment than traditional analog power design.
<b>TPU</b>
The Ultimate Turbo Processor
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.
<b>EPU</b>
Energy Efficiency All Around
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!
