The ASUS ROG Maximus IV Extreme-Z is the latest model in a long line of ROG motherboards designed from the ground up to be an overclocking enthusiast's dream come true. The ASUS ROG Extreme boards have always been about giving full features and maximum overclocking potential and the Maximus IV Extreme-Z is no exception.

Lucid® Virtu™ is a GPU virtualization software which along with 2nd generation Intel® Core processor featuring like Intel Quick Sync can enable an all-inclusive media platform and discrete GPUs coming with high-end DirectX 11 3D, anti-aliasing and performance features to get the thrills in games. Ultimately, users can enjoy optimal simultaneous performance in 3D gaming and video functions like transcoding and HD playback without having to manually change settings between GPUs. Also on board are dual Gigabit Intel® Ethernet ports and dual-channel DDR3 2400(O.C.) DRAM.

Intel® Smart Response Technology boosts overall system performance using an installed fast SSD (min 18.6GB available) as a cache for frequently accessed operations, speeding up hard drive/main memory interaction. Key benefits are expedited hard drive speeds, reduced load and wait times and maximised storage utilisation.

Extreme Engine Digi+ equipped with high performance digital VRM design can easily achieve the ultimate performance with adjustable CPU PWM frequency. It expedites heat dissipation and achieves better electric conduction keeping critical components reliable. Extreme Engine Digi+ balances the need for voltage and the desire for rock solid performance to bring the ultimate user experience.

What's more is the Maximus IV Extreme-Z comes with an exclusive ROG OC Kit. This includes, LN2 mode which when activated optimises the ROG board to stop cold-boot bug during POST at the most extreme low temperature when using liquid nitrogen. Also included is a PCIe x 16 lane switch which helps to quickly identify and trouble shoot individual VGA functionality. The final feature of this exclusive package is Q Reset which smartly clears CMOS and quickly by passes S5 mode to reboot the system.
