Back to where ROG began

Based on Intel Z270 chipset, this board offers a solid foundation for building a powerhouse based on 6th/7th generation Intel Core processors. The new ROG Maximus IX Apex delivers bold design and unparalleled power, hearkening back to the origins of the brand. With an optimized layout and radical aesthetics, the Apex is engineered to smash performance boundaries and to look good while doing it. That makes it the perfect motherboard for overclocking addicts who push their system to the limits, or for enthusiasts who want to build a showcase gaming rig!

  • Designed for 7th generation Intel Core processors to maximize connectivity and speed with USB 3.1 Type A and Type C connections, vertically mounted dual M.2 (via the DIMM.2 adapter) and Intel  Optane Memory compatibility
  • Record-shattering overclocking design with a full suite of onboard features like dual BIOS chips, LN2 mode switch, watercooling system headers, thermal sensor connectors and probelt measurement points.
  • 5-Way Optimization with Auto-Tuning and FanXpert 4 automatically tailors overclocking profiles to your unique build for máximum OC performance and dynamic system cooling
  • Three exclusive SafeSlots feature an injection molding process that integrates metal framing for stronger, firmly anchored PCIe slots built for heavyweight GPUs
  • Unmatched personalization with ASUS exclusive AURA Sync RGB lighting, two additional RGB headers and a 3D-printing friendly design

Redefining the limits

Maximus IX Apex is a motherboard built for serious performance. The ROG R&D team redefined boundaries with the Apex design -- elevating its overclocking potential to dizzying heights. Manufactured using some of the industry's highest-quality components, the Apex features a convention-breaking two-slot memory design on EATX to enable a highly optimized trace layout that reduces crosstalk and improves signal integrity. The Apex has already surpassed performance peaks by setting multiple world records to achieve global first places, breaking several long-standing records in the process. Among these record-breaking performances is the best Intel© Core CPU-frequency since the X58 platform-based motherboards, with a single-core, single-thread frequency of 7.383GHz, and 7.328MHz at four cores and eight threads. The new board has also set a reference base-clock (BCLK) record at 584MHz, and a memory frequency surpassing 5GHz in single channel — turning in a breathtaking 5041MHz! In total, Maximus IX Apex has secured eight WRs and 18 GFPs.

* All world records and global first places were verified on January 25, 2017, and are recorded at

Overclocker's Toolkit - 12 hardware-level controls

Maximus IX Apex includes an overclocker's toolkit with a dozen 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, DRAM jumpers for quick memory configuration, and four PCIe switches for quick slot toggling. Other tools include Safe Boot and ReTry buttons, an LN2 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 more records!v

Condensation detection

Specialized circuitry allows Maximus IX Apex to detect when condensation occurs on the back of the board. Divided into three distinct sections — CPU, DRAM and PCIe — the feature provides a useful warning when an area may be at risk of short-circuiting.

Bar-raising memory overclocking

ROG engineers adopted a two-slot memory design on an EATX motherboard, enabling a highly optimized layout for memory trace paths to minimize noise and improve signal integrity while allowing DDR4 overclocking to 4266MHz and beyond. ROG also works with all the major DDR4 memory vendors to ensure the best compatibility and real-world performance.

ASUS Pro Clock technology with Extreme Engine Digi+

The dedicated base-clock (BCLK) generator designed for 7th Generation Intel© processors is what allowed Apex to set an overclocked BCLK frequency record of 584MHz*. This custom solution works in tandem with the ASUS TurboV Processing Unit (TPU) to enhance voltage and base-clock overclocking control — providing an exciting new way to boost performance to extreme heights. And, of course, Maximus IX Apex includes Extreme Engine Digi+ — ROG's revered digital power controller. With Texas Instruments NexFET MOSFETs, and with MicroFine alloy chokes, the Digi+ PWM controller with 10K black metallic capacitors and Extreme Engine Digi+ technology always delivers the stable and smooth core voltages.

* Base-clock overclocking range will vary according to CPU capabilities, cooling, motherboard support and tuning options. Ranges up to 650MHz are possible under some conditions.
