1.1.2 ASUS 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 either through carefully developed automated modes, or by using user-

dened proles. The result is that DIGI+ VRM technology ensures better energy efciency

and precise power delivery. Boosted by world-renowned ASUS quality, DIGI+ VRM creates

an ideal computing platform for a diverse range of applications, from gaming to multimedia

or ofce work and heavy multitasking. Engineered and tested to assure unmitigated

performance, ASUS A55 boards with DIGI+ VRM remain efcient and accurate for reliable

performance in every scenario.

* DIGI+ VRM features are also available in FM2 socket compatible CPUs
