Flagship performance 

Drive CPU and DDR4 performance beyond all expectations!
Patent Pending OC Socket
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.

Unique Cache Bus Voltage Adjustment
Cache bus links areas such as CPU cores, DDR4 Memory Controllers, System Agent and the shared L3 Cache. It is a critical interconnect for the whole CPU subsystem. Higher cache bus frequency directly gives faster total sub-system performance. ASUS OC Socket exclusively provides an adjustable cache bus voltage to reach higher cache bus frequencies.
Reference tuning ratio range is up to 30. ASUS OC Socket tuning ratio range is 45+!
Cache bus links all the essential CPU areas together. Higher cache bus frequency boosts PC performance!

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

All-round energy efficiency EPU
With the Energy Processing Unit (EPU) you will enjoy from system-wide real-time power savings, controlled via a simple onboard switch or the AI Suite 3 utility. EPU detects and adjusts power consumption according to the PC's needs — automatically. It can also reduce CPU wattage to an indicated level or enjoy even more savings with Away Mode, which creates an extreme energy-saving scenario by shutting down unused extra I/O controllers and reduces the graphics cards' power level while you're away, so the PC consumes only the energy it needs — and not a drop more!

Advanced fan controls for ultimate cooling and quietness EPU
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.

Precise Digital Power Control DIGI+ Power Control
Power control is one of the most essential motherboard designs. Intelligent CPU power draw detection with ASUS DIGI+ Power Control is an innovative, industry-leading technology that fully complies with Intel VRD12.5 specifications, increasing overclocking potential, enhancing system stability, and improving power efficiency with superior flexibility and accurate control.

App specific optimization for professionals and gamers Turbo App
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.

Ultra-fast transfer speed 

10Gb/s USB 3.1 built in to the board
With the latest USB 3.1 connectivity built in and dual Type-A ports for the very fastest USB data transfers, you'll experience data-transfer speeds of up to 10Gbit/s — or twice as fast USB 3.0. The next-generation standard is completely backward-compatible with your existing USB devices, and you'll be all set for USB 3.1's breakneck speeds. And ASUS-exclusive USB 3.1 Boost technology automatically accelerates USB 3.1 performance even further!

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 x4 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.

Intel Gigabit Ethernet —top gaming choice that goes faster with your CPU
Faster, smoother gaming – always. Intel Gigabit Ethernet has the serious double advantage of communicating directly with CPUs and offering high TCP and UDP throughput. This significantly reduces the processor's workload, so there's more power for your game and your gameplay.

Up to 2X-faster UDP game-data performance
ASUS engineers used IxChariot, an independent network-assessment test tool, to determine just how much quicker Intel Gigabit Ethernet deals with the smaller (sub-256 byte) UDP data packets that are vital for responsive gaming. The results are in — and with X99 your game-data packets flow up to two times (2X) faster than competing gaming-LAN technologies!

Multi-GPU support
With support for both NVIDIA SLI and AMD CrossFireX 2/3-WAY configurations, the X99 motherboard enables multi-GPU setups so you can harness the full power of the latest graphics technologies to drive games at 4K and beyond.
