ASUS motherboards using the Intel H61 chipset employ precise digital voltage regulation for the CPU, called DIGI+ VRM (Voltage Regulation Modules) digital power design. The CPU voltage & VRM frequency are adjusted via either carefully developed automated modes, or by using user-defined profiles. The effect is that DIGI+ VRM technology ensures greater energy efficiency & the best possible PC stability. 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 & heavy multitasking. Engineered & tested to assure unmitigated performance, ASUS H61 boards with DIGI+ VRM remain efficient & stability, for reliable application in every scenario. ASUS motherboard back I/O panels are made from strong & corrosion-resistant stainless steel, which is bonded with a thin layer of chromium oxide to enhance the anti-corrosion properties. Thats why ASUS stainless steel back I/O panels have a usage life three times longer compared to ordinary panels.
