Performance Pushed to the Apex
Maximus XI Apex is the premiere overclocking platform for LN2 addicts who live to unlock the full potential of Intel’s latest multi-core CPUs. With an optimized layout, enhanced power delivery and control, unique double-capacity DIMM support, and stacks of striking design and customization elements, Apex is engineered for performance, gaming and style enthusiasts alike. Feed your performance habit, with Maximus XI Apex.
Power and Finesse
With hardware-level overclocking controls, enhanced memory support, extensive cooling options, Maximus XI Apex is designed to push through every performance limit. The board even includes AI smarts that provide automated CPU overclocking for newcomers and quick tuning information for experts.
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. ROG Maximus XI Apex features a dedicated onboard clock generator that supplies dynamic reference clocks to the CPU cores and major subdomains, giving you the freedom to coax every MHz of headroom from the system.
Apex also benefits from Extreme Engine Digi+, ROG's revered digital power controller fed by dual 8-pin ProCool power connectors. With PowIRstage® MOSFETs, MicroFine alloy chokes, 10K black metallic capacitors, and the Digi+ PWM controller, Extreme Engine Digi+ technology delivers clean, stable power. The board even has a finned VRM heatsink to maximize the dissipation surface area, keeping crucial components running cooler.

ROG Maximus XI Apex includes an overclocker's toolkit with hardware-level controls to aid
your overclocking experience. The motherboard's Dual BIOS allows you to experiment with
different firmware versions and provides a path for recovery in case one becomes corrupt,
and the onboard switch allows you to easily change between the first and second BIOS. The
overclocker's toolkit also includes a Pause switch to halt the system. Other tools include
Safe Boot and ReTry buttons, a LN2 mode jumper to aid POST at sub-zero temperatures, and a
Slow mode switch. Combined, they're quick and easy time-savers designed to help you break
*Slow mode and Pause switches require that LN2 mode is enabled.
Four LEDs to show current boot status.
Instantly retune memory settings for a guaranteed boot.
Check the voltage via integrated measurement points.
One press instantly initiates a hard reset.
Safe Boot Button
Instantly reset the PC and boot directly into a safe mode.
Activate to pause the system and fine-tune OC parameters mid-benchmark.
Slow Mode Switch*
Instantly reduces the CPU ratio to 8X to bypass finicky benchmark passages.
LN2 Mode Jumper
Jumper to enable special options and functions for liquid-nitrogen (LN2) overclocking.
(For Dual BIOS)
Easily switch between BIOS one and two.
Specialized circuitry allows Maximus XI Apex to detect when condensation occurs on the back of the board. Divided into three distinct sections — CPU, DRAM and PCIe — dedicated onboard LEDs illuminate to provide a clear visual warning when an area may be at risk of short-circuiting.
Onboard LEDs illuminate when condensation is detected in these areas.
With Maximus XI Apex, our engineers adopted a two-slot memory design to enable a shorter trace layout for tighter control over impedance and reduce signal interference. This is teamed with ASUS OptiMem II to preserve memory signal integrity by routing traces and vias to the optimal PCB layer. Together, the enhancements provide more headroom for overclocking and improved stability, allowing Apex to achieve memory speeds of DDR4-4800MHz and beyond.*Overclocking range will vary according to CPU capabilities and cooling.
To provide Intel’s latest CPUs unfettered access to memory bandwidth, we’ve reimagined motherboard trace routing from the ground up. Our OptiMem II tech carefully maps memory signal pathways across different PCB layers to reduce vias and also adds shielding zones that significantly reduce crosstalk.
