This article covers ASRock Intel Z370 チップセット搭載 ATX マザーボード Z370 Taichi.

Overview

The ASRock Z370 Taichi is a high-end ATX motherboard built for Intel 8th Gen Core processors (Coffee Lake). It features a robust 12-phase power delivery design, three Ultra M.2 slots, and integrated Intel wireless networking, making it an excellent choice for enthusiasts who demand stability and expandability. On the audio side, the Realtek ALC1220 codec with Purity Sound 4 delivers 7.1-channel HD audio suitable for gaming and content creation. Powered by the Intel Z370 chipset, this board supports overclocking and memory speeds up to DDR4-4333+ (OC). The LGA1151 socket is compatible only with 8th Gen CPUs, so older Skylake/Kaby Lake processors will not work. Three PCIe 3.0 x16 slots (two running at x16 full bandwidth) allow multi-GPU configurations. With eight SATA3 ports and three M.2 slots, storage expansion is plentiful. Positioned as ASRock's premium offering in the Z370 lineup, the Taichi targets users who prioritize overclocking potential, durability, and rich connectivity.

Compatibility Guide

Only Intel 8th Gen Core CPUs (Coffee Lake) such as i7-8700K, i5-8600K, and i3-8100 are supported. Do not attempt to install 6th or 7th generation processors despite the same LGA1151 socket — they will not boot. Memory support includes four DDR4 slots for non-ECC unbuffered DIMMs, rated from 2133 up to 4333+ MHz via overclocking. The maximum capacity is 64 GB (16 GB per slot). The board uses the standard ATX form factor, fitting most ATX cases. Power delivery requires a 24-pin main connector and an 8-pin CPU power connector. For storage, you get eight SATA3 ports (6 Gbps) and three M.2 slots, all supporting PCIe Gen3 x4 and SATA modes — ideal for high-speed NVMe drives alongside traditional HDDs.

Product Info

Released in October 2017, the Z370 Taichi originally retailed in the ¥25,000–¥30,000 range, placing it in the enthusiast tier. The warranty period is 2 years. Under the hood, ASRock employs a 12-phase DigiPower VRM, 60A chokes, and Nichicon 12K black capacitors for reliable power delivery and longevity. Intel Wireless-AC 3168 is included for Wi-Fi and Bluetooth connectivity.

Best Use Cases

Overclocking Enthusiasts: The 12-phase VRM and premium components provide clean, stable power for pushing Coffee Lake CPUs beyond stock speeds. Users targeting 5 GHz on an 8700K will appreciate the headroom. Multi-GPU Builds: With three PCIe x16 slots (configurations: x16/x8/x4), you can run two NVIDIA or AMD cards comfortably. This suits 3D rendering or deep learning workloads. * Storage-Heavy Workflows: The three M.2 slots and eight SATA ports allow simultaneous use of multiple NVMe SSDs for video editing or database servers, plus large-capacity HDDs for backup.

Things to Consider

The Z370 Taichi only supports 8th Gen Coffee Lake CPUs — no backward compatibility with 6th/7th Gen. If you find a used unit, verify the BIOS version to avoid memory compatibility issues with high-speed kits. The third PCIe x16 slot runs at x4 through the chipset, which may bottleneck a modern graphics card; for best performance, limit multi-GPU setups to two cards. Since this board is now discontinued, warranty support and availability are limited. If you need a current platform with newer features (e.g., USB 3.2 Gen2×2 or PCIe 4.0), consider Z390 or Z490 alternatives.
