General Features
Thrilling Performance
With a dedicated onboard clock generator, support for the high-performance memory, and cooling options to keep thermals under tight control, the ROG Maximus XI Code provides a potent foundation for your next gaming build.
Power Performance
Built for Overclocking
By default, all of Coffee Lake's major bus frequencies are derived from the same reference clock, limiting the control and flexibility needed to harness the full overclocking potential of the platform. The ROG Maximus XI Code features a dedicated onboard clock generator that supplies dynamic reference clocks to the CPU cores and major subdomains, giving you the freedom to coax more MHz of headroom from the system.
DDR4 4400 MHz+
Whether you're gunning for high memory frequencies or tuning timings for the low latency, ROG Maximus XI Code provides the tools you need to exploit the Coffee Lake architecture's full potential: carefully optimized trace pathways maintain signal integrity, and ROG firmware offers the necessary tweaks to ensure stability while maximizing memory performance. Load up with a high-density memory kit for heavy multitasking, or run a focused setup that delivers the bandwidth your favorite games and applications need.
OptiMem II
To provide Intel's CPUs unfettered access to memory bandwidth, ASUS has reimagined motherboard trace routing from the ground up. Their OptiMem II tech carefully maps memory signal pathways across different PCB layers to reduce vias and also adds shielding zones that significantly reduce crosstalk. And to further enhance overclocking headroom for fully stacked memory configurations, they've employed a highly customized T-Topology layout that delivers time-aligned signaling.
