ASUS Exclusive Features

DIGI+ VRM

DIGI+ POWER CONTROL: Digital Power Design for the APU
ASUS motherboards using the AMD® A55 chipset employ precise digital voltage regulation for the APU, called DIGI+ VRM (Voltage Regulation Modules) digital power design. The APU voltage is adjusted via either carefully developed automated modes, or by using user-defined profiles. The effect is that DIGI+ VRM technology ensures greater energy efficiency and the most precise power delivery. Boosted by world-renowned ASUS quality, it creates an ideal computing platform for a diverse range of applications, from gaming to multimedia or office work and heavy multitasking. Engineered and tested to assure unmitigated performance, ASUS A55 boards with DIGI+ VRM remain efficient and accurate, for reliable application in every scenario.

* DIGI+ VRM functions also available in FM2 socket compatible CPUs
