Flagship performance
Drive CPU and DDR4 performance beyond all expectations!
Designed to break performance barriers, ASUS OC Socket utilizes extra pins to connect a proprietary circuit to contacts found on Haswell-E's land grid array (LGA). Combined with our customized UEFI, this exclusive feature enables higher DDR4 memory frequencies, lower latencies and enhanced stability while overclocking, extending all the way to extreme overclocking conditions, such as Liquid Nitrogen (LN2). OC Socket is 100% compatible with new Haswell-E LGA 2011-v3 CPUs, ensuring the ideal combination of overclocking performance and compatibility.
Make your memory go faster
This is the first platform to support DDR4 memory and it's able to drive memory frequencies to 3200MHz (and beyond when overclocked)! ASUS-exclusive T-Topology circuit design plus OC Socket provides superb memory-overclocking capability to unleash the full power of DDR4 by minimizing coupling noise and signal reflection. With innovative equidistant memory channels, it delivers the most balanced control and powerful overclocking compatibility. ASUS works with almost every DDR4 memory vendor to ensure the best compatibility

Fan Xpert 3
Fan Xpert 3 puts 4-pin/3-pin CPU and case fan controls in one place. It scans each fan's characteristics and delivers custom settings for each fan based on the dedicated area temperatures detected by hardware thermal sensors. Make sure every fan achieves the best balance of cooling performance and low noise. Fan Xpert 3 supports hardware-level PWM/DC combo mode for both the CPU and case fans. It even can  reduce the CPU fan speed to below the default minimum, for extra-quiet and power saving operation during light loads.
Ultra-fast transfer speed
Media-acclaimed UEFI BIOS
The smoothest, slickest mouse-controlled graphical BIOS has been improved to make it even more appealing. Whether you're a PC novice or a seasoned overclocker, the EZ and Advanced Modes help you find your way, quickly and easily.
Evolve your storage speed with SATA Express
SATA Express provides up to 10Gbit/s data-transfer speeds from two PCIE 2.0 lanes, resolving the higher bandwidth request in the near future. The current SSDs consume up to 550MB/s, which is close to saturation point for SATA 6Gbit/s connections. Backwardly compatible with up to two SATA drives, SATA Express is the next-generation connectivity standard — and ensures that you and your system won't get left behind.
Speed up with onboard M.2 up to 32Gb/s
With a 4 x PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gb/s data-transfer speeds. It is the perfect choice for an operating system or application drive, making your whole PC or professional apps work as fast as possible.
App specific optimization for professionals and gamers
Gamers and professionals can get benefit from app specific optimizations by the exclusive ASUS Turbo App. Its intuitive tuning panel boosts a range of hardware; overclock your CPU, tune your fans, prioritize network data and optimize audio settings automatically.
