Asus F2A55-M LK2 AMD A55 FM2 DDR3 mATX


This motherboard supports AMD A-series accelerated processor with AMD Radeon HD graphics. This revolutionary APU (Accelerated Processing Unit) combines processing power and advanced DirectX 11 graphics in one small, energy-efficient design to enable accelerated performance and an industry-leading visual experience. It features dual-channel DDR3 memory support and accelerates data transfer rate up to 5 Gtps.

ASUS motherboards using the AMD A55 chipset employ precise digital voltage regulation for the APU, called DIGI+ VRM 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.
