ASUS T-Topology
Make your memory go faster

ASUS T-Topology allows memory frequencies that are higher than ever — to 4133MHz and beyond. ASUS-exclusive T-Topology circuit design provides superb memory-overclocking capability to unleash the full power of DDR4 by minimizing coupling noise and signal reflection. Refined manufacturing ensures ultra-consistent quality, minimal crosstalk between custom trace paths, and time-aligned signaling for superior stability and compatibility.

Thermal Radar 3
Instant fan tuning, complete system cooling

Our Thermal Radar 3 software allows you to control connected chassis fans, water pumps, AIOs, and even the fans of ASUS graphics cards — all to provide ultimate cooling performance for gaming and productivity. Multiple onboard sensors also enable the temperatures of key components to be monitored in real time, so you can assess and optimize cooling efficiency.
