ASUS X99 Series motherboards are engineered from the ground up to get the most from new Intel® Core™ i7 processor family for socket LGA 2011-v3 and extract every ounce of performance from Intel's latest architecture. ASUS delivers the BEST of motherboards for gamers, enthusiasts, content creation professionals and passionate DIYers.
ASUS Pioneered OC Socket
Designed to break performance barriers, ASUS OC Socket utilizes extra pins to connect a proprietary circuit to contacts found on 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 all LGA 2011-v3 CPUs, ensuring the ideal combination of overclocking performance and compatibility.
Unique Cache Bus Voltage Adjustment
The cache bus links areas such as CPU cores, DDR4 memory controllers, system agent and the shared L3 cache — so it's a critical interconnect for the whole CPU subsystem. A higher cache-bus frequency directly accelerates subsystem performance, so 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!
Drive your memory frequencies to 3333MHz and beyond! ASUS-exclusive T-Topology circuit design plus OC Socket provides a 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.
5-way Optimization
One click takes care of all that complex tuning. Your PC is smart with ASUS 5-Way Optimization. It dynamically optimizes essential aspects of your system based on real-time use — so you get superb CPU performance, everyday energy savings, ultra-stable digital power, cool and quiet fans and now even networking and audio settings that are tailored for the apps that you are using. In short, 5-Way Optimization ensures that your PC is perfect for gaming, entertainment, productivity or just about anything else!
Unleash your PC's full performance with a simple two-phase onboard switch or the ASUS AI Suite 3 utility! The TurboV Processing Unit (TPU) offers precise voltage control and advanced monitoring for the CPU and the graphics card, enabling great freedom to adjust CPU frequencies and ratios for optimized performance and to exploit the potential out of your graphics card*.

With the Energy Processing Unit (EPU) you'll enjoy real-time, system-wide power savings. EPU detects and adjusts power consumption according to the PC's needs — automatically. It can also reduce CPU wattage to a set level and deliver even more savings with Away Mode. This 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!
The latest ASUS X99 motherboards feature the most advanced cooling capability to date, controllable from both Fan Xpert 4 and UEFI.
Full control of PWM or DC water pumps, perfect for both custom and self-contained cooling setups.
A dedicated fan header that can supply up to 3 Amps, for high-speed high-current fans.
Multiple temperature sources: Each header can be set to monitor and react up to 3 multiple thermal sensors.
Every onboard header supports auto detection of PWM or DC fans.
A dedicated integrated circuit that protects each fan header from both overtemperature and overcurrent.
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® IMVP8 specifications, increasing overclocking potential, enhancing system stability, and improving power efficiency with superior flexibility and accurate control.
Whether hardcore gamer or business professional, you'll feel the benefit of the ASUS-exclusive Turbo App every day. Its intuitive tuning panel boosts a range of hardware, overclocking your CPU, tuning your fans, prioritizing network data and optimizing audio settings — all with automated ease!
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.
Update the latest BIOS via the internet, and from within the BIOS.
Check up your storages devices' Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T) logs to gauge reliability, and even determine if they're about to fail.
Select your hardware and apply different scenarios to tune system performance, or streamline your RAID configuration for faster data retrieval and backups!
Quickly find tuning options and add preferred tools to the list.
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB control with a variety of functional presets for both built-in RGB LEDs, as well as LED strips connected to the onboard 4-pin RGB headers, all of which can be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process integrates the slot with the fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.
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.
