Model Z890 Taichi OCF

  • Supports Intel Core Ultra Series 2 processors via LGA 1851 socket
  • 22+1+2+1+1 power phases with 110A SPS deliver stable extreme overclocking
  • Two DDR5 DIMM slots reach 10133+ MHz (OC) for maximum memory speed
  • Dual PCIe 5.0 x16 plus PCIe 4.0 x4 provide high-bandwidth expansion
  • Realtek ALC4082 7.1-channel HD audio with Nahimic enhances sound quality

Built for extreme overclocking

The ASRock Z890 Taichi OCF is an LGA 1851 ATX motherboard designed for Intel Core Ultra Series 2 processors. Its 22+1+2+1+1 phase power design with 110A SPS stages targets competitive overclockers and enthusiasts who demand maximum CPU headroom. Dual-channel DDR5 support reaches 10133+ MT/s when overclocked on the two 288-pin slots.

Verify CPU cooler clearance and power delivery

Confirm your chassis accommodates an ATX board and that your CPU cooler mounting matches LGA 1851. The board draws auxiliary power through standard EPS connectors to feed the 110A VCore phases. Only two DDR5 DIMM slots are populated, so plan memory capacity up to 128 GB using high-frequency kits validated for 1DPC operation. Four SATA 6Gb/s ports and three M.2 sockets provide storage flexibility.

Replaces earlier Z790 flagship boards

Moving from a Z790 platform adds the LGA 1851 socket, PCIe 5.0 x16 graphics slots, and a CPU-attached PCIe 5.0 M.2 running at 128 Gb/s. The jump is worth it when you need native DDR5 speeds beyond 6400 MT/s, dual Thunderbolt 4 Type-C ports, or the 5 Gbps LAN controller for high-throughput networking.

Questions about this item

Does the ASRock Z890 Taichi OCF come with RAM or do I need to buy DDR5 modules separately?

The board ships without memory; you must purchase DDR5 DIMMs separately. It has two 288-pin slots supporting up to 128 GB total in dual-channel mode, with native 6400 MHz and overclocked speeds up to 10133 MHz.

Should I choose 1-rank or 2-rank DDR5 kits for the highest overclock on this board?

For maximum frequency, 1-rank (1R) modules are specified up to 10133 MHz (OC), while 2-rank (2R) modules top out at 6800 MHz (OC). Both run at 6400 MHz natively.

What does the 10133 MHz memory figure mean once the system is built?

It is the peak overclocked transfer rate achievable with 1-rank DDR5 kits under optimal cooling and tuning; everyday stability will depend on the specific memory ICs, CPU memory controller, and voltage headroom.
