    ASUS Introduces Hybrid Motherboards that Deliver Fast Performance and Uncompromising Stability

    The ASUS P7P55D Series Features the Latest Intel Chipset, 48 Hybrid Phase Power, and SATA 6Gbps Connectivity for the Ultimate in Performance

    Taipei, Taiwan, September 8, 2009 – ASUS, the leading innovator of advanced motherboard solutions, today launched the ASUS P7P55D Series motherboards. Featuring the Intel® P55 Express chipset, the P7P55D Series supports the latest LGA 1156 socket for Intel® Core™ i7/Core™ i5 Processors for maximum performance. The P7P55 Series is based on groundbreaking "Xtreme Design", a winning design formula drawn from many years of engineering innovation, to optimize overall system performance and hardware reliability. It also includes the latest Hybrid Technology—Hybrid Processor, Hybrid Phase, and Hybrid OS—to give users intelligent performance enhancement, active cooling, and rapid online access.

    Achieving 6Gbps Storage Bandwidth with Exclusive Expansion Bridge

    Equipped with a specially-designed onboard chip, the P7P55D Premium is the first motherboard to natively support 6Gbps data transfer bandwidth with the latest SATA storage interface. With this expansion bridge, the P7P55D Premium unleashes the performance potential of the latest hard disk drives, achieving almost double the throughput from existing SATA compatible drives. By eliminating any transmission bottlenecks, the expansion bridge enables 50% faster reading and writing of disk data. For other P7P55D Series models, ASUS also provides an expansion card to achieve the same results.

    Optimizing Efficiency with Revolutionary Hybrid Phase Power Delivery

    Users can expect maximum power efficiency, extremely cool operations, and enhanced component longevity from the P7P55D Series. With its Hybrid Phase Technology—combining ASUS Xtreme Phase with ASUS T.Probe—the series delivers maximum efficiency and extremely stable power. P7P55D Premium's 48 Hybrid Phase technology is the most power-efficient design in the industry, surpassing other 48-phase prototype motherboards. ASUS T.Probe is the world's first active cooling technology that detects and balances power phase loadings and temperatures in real time—especially around the active CPU. A new frequency conversion technology further improves efficiency by maximizing energy utility. High-grade materials also help enhance component longevity and further minimize power loss. Additionally, the P7P55D Premium includes Stack Cool 3+, and is the world's first motherboard with four layers of 2Oz copper in an 8-layer PCB design. This delivers ultra-cool performance even under extreme overclocking conditions.

    Enhancing Performance with Intelligent Hybrid Processor

    With its new Hybrid Processor, the P7P55D Series lets users achieve superior overclocking performance with the latest Intel CPU and the ASUS TurboV EVO, which functions like a second microprocessor. Both novice and hardcore overclockers can easily boost system performance with TurboV EVO's intuitive interface. Additionally, overclocking is simplified by onboard tools including Auto Tuning which automatically overclocks the system to an extreme yet stable state; ASUS OC Profile which offers the best overclocking settings for different scenarios; ASUS Turbo Key which creates more physical overclocking buttons on the keyboard for instantaneous overclocking; and ASUS TurboV Remote* which allows users to overclock from a convenient controller.

    Hybrid OS Delivers Express Gate and Windows 7 Benefits

    Hybrid OS integrates Windows® and ASUS Express Gate onto the ASUS P7P55D Series for more flexibility. Users can upgrade to Windows® 7 and have better security and faster performance, while Express Gate delivers rapid access to online applications—within five seconds.
