AMD X399 sTR4 Micro ATX board
The ASRock X399M TAICHI pairs the AMD X399 chipset with the sTR4 socket for Ryzen Threadripper processors. Four 288-pin slots support quad-channel DDR4 up to 64 GB. Three full-length PCI Express 3.0 x16 slots and two Ultra M.2 sockets give high-bandwidth expansion in a Micro ATX footprint.
Sustained-load behaviour
Heavy multi-threaded workloads run across all Threadripper cores while the quad-channel memory controller feeds data at up to 3600 MT/s when overclocked. Dual Intel I211AT 1 Gbps LAN ports and the bundled Intel 802.11 ac Wi-Fi module maintain network throughput without thermal throttling during long render or compile sessions.
Practical interface limits
PCI Express 3.0 x16 slots deliver 16 GT/s per lane; each Ultra M.2 socket caps at Gen3 x4 for 32 Gb/s. SATA3 ports top out at 6.0 Gb/s with RAID 0/1/10 support. Wireless reaches 433 Mbps on 2.4/5 GHz bands and Bluetooth 4.2 handles peripheral traffic.

Questions sur cet article
How loud or hot does the ASRock X399M TAICHI get when running a Threadripper CPU all day?
The board has no onboard video chipset so it relies entirely on your CPU cooler and case airflow; the 15 µm gold contacts on the three PCIe x16 slots and the dual Intel I211AT LAN chips add negligible heat, while the Realtek ALC1220 audio and bundled 802.11 ac Wi-Fi module draw very little power.
What other parts must I already own for this motherboard to work?
You need a Ryzen Threadripper processor for the sTR4 socket, DDR4 memory modules up to 64 GB total across the four 288-pin slots, a graphics card because there is no integrated video, and a power supply with the required EPS connectors for the CPU and PCIe devices.
Will my existing SATA SSDs and PCIe 3.0 add-in cards work with this X399 board?
Yes — the board provides eight SATA3 6.0 Gb/s ports with RAID 0/1/10 support and three PCI Express 3.0 x16 slots that can run at x16/x16/x16, so older SATA drives and PCIe 3.0 cards install and operate normally.
