Socket and chipset

The ASUS ROG Maximus XI Apex is an ATX motherboard built around the Intel Z390 chipset and the LGA 1151 socket. It supports DDR4 memory up to a maximum of 64GB, making it a suitable foundation for high-performance desktop builds that require this specific platform.

Who this suits

This board suits enthusiasts assembling a system on the Z390 platform who need the full 64GB DDR4 capacity and the feature set of the ROG Maximus XI Apex. Buyers who want a different chipset, a different socket, or a motherboard that ships with a full accessory kit should look at something else.

Deciding specification

The LGA 1151 socket paired with the Intel Z390 chipset is the single specification that decides whether this is the right part. If your processor and build plan require this exact socket and chipset combination, the board matches the requirement; otherwise it will not fit the system.

Questions about this item

How do I install the board into an ATX case and what step is often missed?

Mount the ATX board using the standard screw holes, fit the supplied I/O back panel before securing it, then connect the single included SATA cable to your drive.

What maintenance will the motherboard need over time?

The metal battery supplied with the board maintains BIOS settings and will eventually need replacement when the system loses time or date after power-off.

What limit appears first when the board runs under sustained load?

Memory capacity tops out at 64 GB DDR4, so heavy multitasking or large datasets will hit that ceiling before other bottlenecks.
