Socket LGA 1151 Z390 ATX board

This Intel Z390 motherboard fits LGA 1151 processors from the 9000 series, 8th generation Core, Pentium Gold and Celeron lines. The ATX form factor provides three PCIe 3.0 x16 slots and three PCIe 3.0 x1 slots for graphics and add-in cards. Dual-channel DDR4 memory runs up to 4400 MHz with a maximum capacity of 128 GB.

Back-panel I/O and bundled items

The rear I/O includes one USB 3.1 Gen2 Type-C port, one USB 3.1 Gen2 Type-A port and six USB 3.1 Gen1 ports for peripherals. Intel I219-V Gigabit LAN and Realtek ALC1220P 7.1 channel audio with S/PDIF are integrated. The package supplies the board, a chassis I/O shield, one SATA cable and a metal battery.

PCIe 3.0 and DDR4 limits

Three PCIe 3.0 x16 slots operate in x16/x0/x4 or x8/x8/x4 configurations, capping multi-GPU bandwidth at PCIe 3.0 speeds. Memory tops out at DDR4 4400 MHz in dual-channel mode with a 128 GB ceiling. Six SATA III ports and an M.2 interface handle storage, all sharing the chipset's PCIe 3.0 lanes.

Questions about this item

Will the Intel I219-V LAN controller need any replacement or maintenance over time?

The Intel I219-V Gigabit network controller is integrated into the board and has no moving parts, so it does not require scheduled replacement or maintenance.

What is the first limit reached when running all three PCIe 3.0 x16 slots at x8/x8/x4 mode continuously?

The CPU provides 16 PCIe 3.0 lanes, so the x8/x8/x4 configuration uses every available lane and becomes the bandwidth ceiling under sustained multi-device loads.

How much heat and power does the Realtek ALC1220P audio chipset add during all-day operation?

The Realtek ALC1220P is a low-power audio codec; its heat output and power draw are negligible compared to the CPU and VRM areas, so it does not raise system temperatures or noise noticeably.
