ASROCK Z390 Extreme4 DDR4 Intel Motherboard

The ASRock Z390 Extreme4 is a full-size ATX motherboard built around Intel's Z390 chipset, designed to support 8th and 9th Generation Intel Core processors via the LGA 1151 socket. Its 12-phase digital VRM design, paired with a 60A power choke, Dual-Stack MOSFETs, and Nichicon 12K Black capacitors, delivers stable and clean power delivery suited for both stock operation and CPU overclocking—including support for Intel K-series unlocked processors and BCLK full-range overclocking. The board accommodates up to four DDR4 DIMMs in dual-channel configuration, supporting speeds from DDR4-2133 up to DDR4-4300 (OC), with a maximum capacity of 128 GB. Intel XMP 2.0 profiles are supported for straightforward memory tuning. Two Ultra M.2 sockets (M2_1 and M2_2) accept PCIe Gen3 x4 (up to 32 Gb/s) or SATA3 modules in sizes up to 2280 (M2_1) and 22110 (M2_2), and both are covered by a full-coverage aluminum M.2 heatsink to manage SSD thermals. Storage is further expanded by eight SATA3 6 Gb/s ports (six via the Z390 chipset supporting RAID 0/1/5/10, plus two via ASMedia ASM1061), and Intel Optane Technology is supported. For expansion, three PCIe 3.0 x16 slots (steel-reinforced) support NVIDIA Quad SLI and AMD Quad CrossFireX multi-GPU configurations, while three PCIe 3.0 x1 flexible slots provide additional card options. A Key-E M.2 slot accommodates optional WiFi/Bluetooth modules including Intel CNVi. Connectivity includes two rear USB 3.1 Gen2 ports (one Type-A, one Type-C, both at 10 Gb/s with ReDriver), four rear USB 3.1 Gen1 Type-A ports, and front-panel headers for four USB 3.1 Gen1 ports plus one front-panel USB 3.1 Gen1 Type-C header. Display outputs on the rear I/O cover HDMI 1.4 (up to 4K@30Hz), DisplayPort 1.2 (up to 4K@60Hz), and D-Sub (up to 1920×1200@60Hz), with triple-monitor support for CPU-integrated graphics. Audio is handled by the Realtek ALC1220 codec under ASRock's Purity Sound 4 platform, delivering 7.1-channel HD audio with a 120 dB SNR DAC, separate PCB layers for left and right channels, Nichicon Fine Gold audio capacitors, a NE5532 headset amplifier supporting up to 600 Ohm headsets, and DTS Connect support. Networking is provided by an Intel I219V Gigabit LAN controller with ESD/lightning protection, Wake- LAN, and 802.3az Energy Efficient Ethernet. RGB lighting is managed through ASRock Polychrome SYNC, with two 12V RGB headers (up to 36W total) and one addressable 5V RGB header (up to 15W). The dual AMI UEFI BIOS setup (main + backup, 128 Mb each) includes Secure Backup technology, while software utilities include ASRock A-Tuning and XFast LAN.
