Drive CPU and DDR4 performance beyond all expectations!

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.

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.
