Z370 chipset for 8th and 9th Gen Intel Core

The ASRock Z370 Extreme4 is an ATX motherboard built on the Intel Z370 chipset. It accepts LGA 1151 processors from the 8th and 9th generations and is not backward compatible with older LGA 1151 CPUs. The board targets system builders assembling embedded solutions or desktop workstations that require a standard ATX form factor and the Z370 feature set.

Four DDR4 slots with extensive overclocking support

Four 288-pin slots accept DDR4 memory up to 64 GB total capacity. The memory standard is DDR4 2133, while the BIOS enables overclocked speeds ranging from 2400 up to 4333+ when paired with compatible modules and 8th or 9th Gen processors. Six SATA 6.0 Gb/s ports provide internal storage connectivity. Dual onboard LAN controllers each deliver 10/100/1000 Mbps wired networking for redundant or segmented traffic.

Standard ATX layout with HDMI and USB 3.1

The ATX dimensions fit common chassis and allow straightforward mounting with standard standoffs. Rear I/O includes HDMI video output for processors with integrated graphics and USB 3.1 ports for high-speed peripherals. Power delivery and cooling characteristics follow typical Z370-class designs for the supported socket and chipset combination. The BIOS ships upgraded to the latest version for immediate compatibility.

Questions about this item

What maximum DDR4 frequency does the Z370 Extreme4 support with an 8th Generation Intel Core processor?

The board runs DDR4 up to 2666 MT/s natively with an 8th Generation CPU; higher speeds listed require overclocking and compatible modules.

What physical space and power connectors does the ATX form factor require in the chassis?

The motherboard needs a standard ATX case with matching standoff holes, a 24-pin ATX power connector and an 8-pin CPU power connector.

Which BIOS step is often missed when installing an 8th or 9th Generation processor on this board?

The BIOS must be updated to the latest version before the new CPU is installed, otherwise the system will not post.
