ASROCK Z370 Extreme4 DDR4 Intel Motherboard

The ASRock Z370 Extreme4 is a full-size ATX motherboard (12.0 in x 9.6 in / 30.5 cm x 24.4 cm) built on Intel's Z370 chipset with an LGA 1151 socket, designed specifically for 8th Generation Intel Core processors including K-Series unlocked CPUs. It features a 12-phase digital power delivery design with a 60A power choke, Dual-Stack MOSFETs, and Nichicon 12K Black capacitors under the ASRock Super Alloy platform, providing stable voltage regulation for sustained workloads and overclocking sessions. BCLK full-range overclocking is supported alongside Intel Turbo Boost 2.0 technology. Memory is handled by four DDR4 DIMM slots in dual-channel configuration supporting up to 64 GB of non-ECC unbuffered memory. Stock speeds of DDR4-2133, 2400, and 2666 are complemented by XMP 2.0 profiles reaching up to DDR4-4333 (OC). The ASRock 4-Layer Memory POOL (Planes on Outer Layers) technology and optimized trace routing are designed to improve signal integrity across all DIMM slots. Storage connectivity includes eight SATA3 6.0 Gb/s ports — six natively supporting RAID 0/1/5/10 via Intel Rapid Storage Technology 15, plus two additional ports via an ASMedia ASM1061 controller. Two Ultra M.2 sockets (M2_1 and M2_2) each support PCIe Gen3 x4 (up to 32 Gb/s) and SATA3 modules in M Key form factors up to 2280 (M2_2 also supports 22110). Expansion is served by three PCIe 3.0 x16 slots (configurable as x16/x8+x8/x8+x8+x4) and three PCIe 3.0 x1 Flexible slots, with support for NVIDIA Quad SLI and AMD Quad CrossFireX multi-GPU configurations. A Key-E M.2 socket accepts type 2230 Wi-Fi/Bluetooth modules. Audio is powered by the Realtek ALC1220 codec under ASRock's Purity Sound 4 platform: 7.1-channel HD output with a 120 dB SNR DAC, individual PCB layers per stereo channel, Nichicon Fine Gold audio capacitors, an NE5532 headset amplifier supporting impedances up to 600 Ohm, and DTS Connect support. Networking uses an Intel I219V Gigabit LAN controller with Wake- LAN, Energy Efficient Ethernet (802.3az), ESD protection, and PXE support. Rear I/O includes one USB 3.1 Gen2 Type-A and one Gen2 Type-C port (both 10 Gb/s via ASMedia ASM3142), four USB 3.1 Gen1 ports, HDMI (up to 4K/30Hz), DVI-D (up to 1920x1200), D-Sub (up to 1920x1200), optical S/PDIF out, RJ-45 LAN, PS/2, and six HD audio jacks. A Thunderbolt AIC connector (5-pin) is present board. The board carries dual AMI UEFI BIOS chips (main + backup) with Crashless BIOS technology, ASRock Instant Flash, and Internet Flash. Certifications include FCC, CE, and ErP/EuP readiness. The included warranty period is 3 years.
