Intel Z390 motherboard for LGA 1151 CPUs

This MSI MEG Z390 ACE board fits Intel Core 9000 Series and 8th Gen processors in the LGA 1151 socket. The ATX layout provides three full-length PCIe 3.0 x16 slots plus three PCIe 3.0 x1 slots for expansion cards. It targets builders who need high-end connectivity and multi-GPU flexibility on the Z390 platform.

128GB DDR4 capacity with 4500MHz support

Four memory slots accept dual-channel DDR4 up to 128GB total, running at speeds up to 4500MHz. Six SATA III ports and an M.2 interface handle storage arrays, while the board runs out of native SATA lanes if every port and M.2 slot is populated simultaneously. Memory headroom is generous for content creation workloads.

Realtek ALC1220 audio and Killer E2500 LAN

Onboard sound uses the Realtek ALC1220 codec for 7.1-channel output with S/PDIF. Networking relies on a single Killer E2500 Gigabit controller. Rear I/O supplies six USB 3.1 Gen2 ports, four Type-A and two Type-C, plus four USB 2.0 Type-A ports; internal headers add four more USB 2.0 connections.

Questions about this item

Will my existing DDR4 4500MHz memory kits run at their rated speed on this board?

The board supports dual-channel DDR4 4500MHz memory and a maximum capacity of 128GB, so compatible kits should operate at that frequency.

How can I verify the Realtek ALC1220 audio and Killer E2500 LAN are active after assembly?

Check Device Manager for the Realtek ALC1220 codec and Killer E2500 controller, then confirm 7.1 channel output and Gigabit link status in their respective control panels.

Which cables and brackets are included and what must I source separately for a build?

The box contains the motherboard, a CMOS battery, one SATA cable and the chassis I/O back panel; CPU cooler, memory, storage drives, power supply and any additional SATA cables are not included.
