Redefining Limits

The Maximus IX Apex is positioned as a true performance-oriented motherboard, with ROG's R&D team breaking all the boundaries to create the most optimal trace layout and highest-quality power delivery. With its 2-DIMM DRAM design, Apex has already surpassed the performance peak by setting multiple world records and global first places to break several long-standing records.

These include the best Intel© Core™ CPU-frequency since the X58 platform-based motherboards, with a record of 7.383GHz on a single core and one thread and 7.328GHz on four cores and eight threads!

It also set a reference clock (BCLK) at 584MHz and a memory frequency surpassing the 5GHz, with 5041MHz. In total, Maximus IX Apex has broken 8 World Records and 13 Global First Places!

Overclocker's Toolkit The Right Tool For The Job

12 Hardware Level Controls
The full spread of onboard ROG overclocking features is present. Dual BIOS/Switch allow you to experiment with different firmware versions and provide a path for recovery in case one becomes corrupt. There're also Pause, DIMM Jumper and PCIe switch, Safe Boot and ReTry buttons. They're quick, easy and real time-savers! There's also an LN2 mode switch to aid POST at sub-zero temperatures, and a Slow Mode switch to help stability at critical moments when at the ragged edge.

Condensation Detection Circuit

Specialized circuitry allows the board to detect when condensation occurs on the back of the board. Divided into 3 distinct sections, the CPU, DRAM, and PCIE, the circuit provides a useful warning for when the each area may be at risk for a short.

Best Gaming Performance


King Of Memory Overclocking: 4,266MHz
With support for DDR4 memory, ROG Strix Z270E Gaming lets you drive memory frequencies to 3866MHz and beyond when overclocked! 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. With innovative equidistant memory channels, T-Topology delivers balanced control and powerful overclocking compatibility.

"The ROG team has raised the bar further on memory overclocking with the latest addition to the ROG family; the Maximus IX Apex. It enabled us to showcase the fastest DDR4-4266 2x 8GB memory kit with the newly launched 7th Gen Intel Core processors at CES 2017."
