The ASRock Z370 Taichi is a high-end socket LGA1151 motherboard based on the Intel Z370 chipset, supporting the eighth generation Core i processors, also known as Coffee Lake. It brings three PCI Express 3.0 x16 slots, eight SATA-600 ports, eight USB 3.0 ports, three USB 3.1 ports, one of them Type C. Let’s take a good look at it!
The Intel Z370 chipset is the high-end model for eighth-gen Intel Core i CPUs. Although this generation uses the same socket (LGA1151) of the older ones, the new motherboards are not compatible with sixth- (Skylake) and seventh-gen (Kaby Lake) CPUs. Also, Coffee Lake processors are not compatible with motherboards based on 100 and 200 chipset series.
Except for the support for the newest generation CPUs, the Z370 is identical to its predecessor, the Z270, offering 24 PCI Express 3.0 lanes controlled by the chipset, six SATA-600 ports, support to Optane, Smart Response (installing an SSD as a cache for the main hard drive), Smart Connect (allowing the computer to receive emails and refresh webpages while in sleep mode), and Rapid Start (faster boot times) technologies.
You can see the ASRock Z370 Taichi motherboard in Figure 1. It uses the ATX form factor, measuring 12” x 9.6” (305 x 244 mm).
The ASRock Z370 Taichi comes with three PCI Express 3.0 x16 slots and two PCI Express 3.0 x1 slots.
The PCI Express x16 slots work on x16/x0/x0, x8/x8/x0, and x8/x4/x4 configurations. Besides that, the PCI Express x1 slots are Flex (have an open end,) which means you can also install video cards on them.
The motherboard supports CrossFire with up to three and SLI with two video cards.
The PCI Express x16 slots are covered by stainless steel shields, that work as a shield against interference, and also improving mechanical strength of each slot.
There are also three M.2 slots, supporting both PCI Express 3.0 x4 and SATA-600. You can install a 22110 standard SSD at one of the slots shown in Figure 2, but in this case you cannot use the other one.

Intel socket LGA1151 CPUs have an embedded memory controller, meaning that it is the processor, not the chipset, that defines what memory technologies you can have and the maximum amount of memory that is possible. The motherboard, however, may have a limitation as to how much memory can be installed.
Eighth-gen Intel CPUs are compatible with DDR4 (up to 2,400 or 2,666 MHz, depending on the model) memory. According to ASRock, the Z370 Taichi supports DDR4 memories up to 4,333 MHz.
The ASRock Z370 Taichi has four memory sockets. You can install up to 64 GiB with this motherboard if you use four 16 GiB modules.
In order to enable the dual-channel mode, you must install two or four memory modules. When installing two memory modules, use the first and third memory slots to enable dual-channel mode.

The Intel Z370 chipset is a single-chip solution, which is also known as a PCH (Platform Controller Hub). This chip has six SATA-600 ports, supporting RAID (0, 1, 10, and 5).
The motherboard comes with these six ports, plus two ports controlled by an ASMedia ASM1061 chip. All of them are installed on the motherboard edge and rotated 90°, so the installation of video cards will not block them.
Three of the ports are shared with the M.2 slots, so if you install a SATA SSD in one of them, the respective port will be disabled.

The Intel Z370 chipset supports 14 USB 2.0 ports and ten USB 3.0 ports. The ASRock Z370 Taichi offers six USB 2.0 ports, available through three headers located on the motherboard. There are eight USB 3.0 ports, four on the rear panel and four available through two headers. There are also three USB 3.1 ports, two on the rear panel (one Type A and one Type C,) and one available on a through a header, controlled by an ASMedia ASM3142 chip.
The ASRock Z370 Taichi does not support FireWire or Thunderbolt ports.
- Supports 8th Generation Intel Core Processors (Socket 1151)
- Supports DDR4 4333+(OC). Supports Purity Sound 4 & DTS Connect
- 3 PCIe 3.0 x16, 2 PCIe 3.0 x1
This motherboard comes with a high-end audio circuit. It uses a Realtek ALC1220 codec, which offers 7.1 audio with a 120 dBA signal-to-noise ratio at the analog outputs and 108 dB for the analog inputs. Unfortunately, no more specs of this codec are available.
All the audio section is physically separated from the other circuitry by a line that reduces the interference and helps the audio section to achieve its nominal signal-to-noise ratios. The capacitors on this circuit are audio models from the Japanese manufacturer Nichicon, and it brings a TI NE5532 headphone amplifer.
The analog audio outputs are independent and the motherboard also comes with an on-board optical SPDIF output.
Figure 5 shows the audio section of the motherboard.

The portrayed motherboard has two Gigabit Ethernet ports, one controlled by an Intel I219V chip, and one controlled by an Intel i211AT chip.
The motherboard also comes with an Intel 3167NGW IEEE 801.11ac Wi-Fi adapter, also supporting Bluetooth 4.2. This adapter comes in an M.2 module installed in a slot near the rear panel, seen in Figure 6.

The Z370 Taichi has a two-digit error code display, two BIOS chips, and RGB LEDs around the chipset. The color of the lights and even a flashing pattern can be set using an application that comes with the product, or in the board setup.
In Figure 8, you can see the BIOS chips and the POST error code display.

The ASRock Z370 Taichi is a very complete motherboard for eighth-gen Core i CPUs. It uses high-end components, like the Nichicon capacitors on the audio section and on the the high efficiency design voltage regulator. It also brings features that make it great for overclocking, like clear CMOS button, POST error code display, etc.
It also offers a high-end audio circuit, a slot configuration that supports up to five video cards, three M.2 slots, and an excellent number of SATA and USB ports. The Wi-Fi interface is also a plus.
Being very similar, in features, to the most high-end motherboards available, but with a great cost/benefit ratio, the ASRock Z370 Taichi is an excellent choice for a computer based on an Intel "Coffee Lake" CPU, for gaming or work.
