Socket LGA 1151 300 Series platform

The ASRock Z390 Extreme4 is an ATX motherboard built on the Intel Z390 chipset for 8th and 9th generation Intel Core processors using the LGA 1151 socket. It is not backward compatible with older LGA 1151 CPUs. The board targets builders who need a full-size layout with multiple expansion slots and high-speed storage options.

12 power phase digital PWM design

A 12 power phase digital PWM arrangement delivers stable current to the CPU during extended workloads. This design helps maintain consistent frequencies when all cores are under sustained load rather than short bursts. The layout supports Turbo Boost Technology 2.0 across compatible 8th and 9th generation processors without throttling caused by voltage droop.

Dual Ultra M.2 sockets with Gen3 x4 lanes

Two Ultra M.2 sockets accept M Key modules up to 2280 length. The primary M2_1 slot operates at PCIe 3.0 x4 for 32Gb/s throughput with NVMe or SATA drives. M2_1 shares bandwidth with two SATA3 ports so only one of the three can be active at a time. The second M.2 socket adds further high-speed storage flexibility.

Questions about this item

How much power do the 12-phase digital PWM and Intel I219-V LAN draw when the board runs all day?

The 12-phase digital PWM delivers efficient CPU power, and the Intel I219-V Gigabit LAN is designed for low-power operation during continuous use.

Which 8th or 9th Gen Intel Core processor must I already have for the LGA 1151 socket to work?

This board requires a 9th or 8th Gen Intel Core CPU with integrated graphics if you plan to use the HDMI, DisplayPort or D-Sub outputs.

Will my existing DDR4-2666 memory run at its rated speed alongside the Z390 chipset?

Yes, DDR4-2666 is natively supported without overclocking, and the four 288-pin slots run in dual-channel mode up to 64 GB total.
