ROG MAXIMUS XI CODE Z390 LGA 1151 ATX

This ATX motherboard uses the Intel Z390 chipset and an LGA 1151 socket. It supports 8th and 9th Generation Intel Core, Pentium Gold and Celeron processors built on a 14 nm process. The board provides four DDR4 DIMM slots with a maximum capacity of 64 GB and a single M.2 slot for storage expansion. It is aimed at enthusiasts building a high-end desktop on the Z390 platform.

Ideal for Z390 upgrades, not for new builds

The board suits owners of compatible 8th or 9th Gen Intel CPUs who need a feature-rich Z390 replacement or upgrade. Builders starting a fresh system should consider newer platforms with current sockets and chipsets. Users requiring multiple M.2 drives or more than one full-length PCIe x16 slot must look at alternative models that provide those connections.

Single M.2 slot limits high-speed storage

Only one M.2 socket is available on this motherboard, so only one M.2 SSD can be installed directly. A second fast drive would need a PCIe adapter card or a SATA connection. Verify that a single M.2 device meets your storage plan before purchasing this board.

Questions about this item

How can I confirm the ROG MAXIMUS XI CODE is posting correctly after installing a CPU and memory?

Power on the board and watch the on-board Q-Code display; a steady CPU temperature reading in the UEFI or a successful boot to the OS installer confirms the Z390 chipset and LGA 1151 socket are functioning.

What ships with the motherboard and what must I source separately?

The listing includes only the motherboard and the I/O shield in an anti-static bag; SATA cables, Wi-Fi antennas, M.2 screws, SLI bridges, driver media and the user manual are not supplied.

Which memory speed should I target for the four DIMM slots on this Z390 board?

The board validates DDR4 up to 4400 MHz when overclocked; choose a kit rated at 3200 MHz or 3600 MHz for stable dual-channel operation across all four slots without manual tuning.
