Purpose-built overclocking board

The ASUS ROG MAXIMUS IX APEX is an Intel Z270 motherboard for the LGA 1151 socket. It supports DDR4 memory up to 32 GB and uses an E-ATX form factor. The board is sold new and includes a SATA cable and the rear I/O panel.

Enthusiasts chasing maximum frequency

This board suits builders who want a layout optimised for high memory clocks and competitive benchmarking. It is not for buyers who need more than 32 GB of system memory or who require additional expansion slots beyond the minimalist design.

Memory ceiling decides the build

The 32 GB maximum memory supported is the single specification that determines whether this motherboard fits the planned workload. If the target system requires more capacity, a different platform must be chosen.

Questions about this item

How do I install the ASUS ROG MAXIMUS IX APEX into an E-ATX case without misaligning the I/O shield?

Fit the supplied chassis I/O back panel into the case cutout from the inside until it clicks, then lower the board so its ports seat fully in the shield before screwing it down.

What component will need replacement first on this Z270 board?

The onboard metal battery maintains CMOS; when the system loses time or reverts to default BIOS settings, replace that cell.

What limit appears first when pushing memory on this 32GB max DDR4 board?

The four DIMM slots top out at 32GB total, so population rules and frequency scaling stop there regardless of cooling.
