Two-DIMM DDR5 platform

The ASRock X870E Taichi OCF is an AM5 ATX motherboard built for Ryzen 7000, 8000 and 9000 series processors. It uses a 1 DIMM per channel layout with two 288-pin slots supporting up to 128 GB of dual-channel DDR5. Enthusiasts gain a clean signal path for extreme memory overclocking via AMD EXPO and Intel XMP 3.0 profiles.

Sustained-load power delivery

The Dr.MOS design with Smart Power Stage technology monitors current and temperature on each phase, delivering smoother power to the CPU during extended workloads. This improves stability when the system runs at high frequency for long periods rather than short bursts. OC buttons provide hardware-level control for extreme overclocking sessions.

Flagship expansion upgrade

Six M.2 slots include two CPU-attached Gen5 x4 sockets for 2280 NVMe drives, adding high-speed storage capacity missing on mainstream boards. USB4 brings 40 Gbps Type-C connectivity and Wi-Fi 7 adds multi-link operation for lower latency. The board replaces lesser chipsets when maximum I/O throughput and memory overclocking headroom are required.

Highlights

  • Dual-channel DDR5 reaches 10400+(OC) with two 288-pin slots
  • 128 GB maximum memory capacity for heavy workloads
  • Two PCIe 5.0 x16 slots run at x16 or x8/x8

Questions about this item

How loud or hot does the Dr.MOS power stage run when the board is pushed all day?

The Dr.MOS design uses Smart Power Stage technology to monitor current and temperature per phase, delivering smoother power to the CPU with enhanced overclocking headroom.

What memory must I already own to populate the two DDR5 slots?

You need un-buffered, non-ECC DDR5 modules; the board supports AMD EXPO and Intel XMP 3.0 profiles up to 10400+(OC) with Ryzen 8000 series CPUs.

Will my existing PCIe 4.0 NVMe drives work in the chipset M.2 slots without losing speed?

The chipset provides M.2 sockets running at PCIe 4.0 x4, so current NVMe SSDs operate at their rated throughput.
