Unleash the true performance of new Intel Core i7 processor family for socket LGA 2011-v3 in future
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.

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 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.

Better Protection from Overcurrent
The extra 4-pin power plug shares current with the standard 8-pin power connector to balance loads and provide ample margin to overclock Intel's latest CPUs to the limit.

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.

Make your memory go faster
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.

One click overclock and cooling, done!
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!
