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.

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
