LGA 1851 Intel Core Ultra Platform

The ASRock Z890 Pro RS is an ATX motherboard built for Intel Core Ultra Series 2 processors on the LGA 1851 socket. It targets builders who want a stable foundation for daily computing and high-performance workloads. The board pairs the Z890 chipset with a 16+1+1+1+1 Dr.MOS power phase design and 1000uF durable capacitors. This combination delivers smooth power delivery for reliable operation.

DDR5 Capacity up to 256GB and 9066MT/s OC

Four 288-pin slots support dual-channel DDR5 up to 256GB total capacity. Native speeds reach 5600MT/s with one DIMM per channel, while overclocked profiles push beyond 9066MT/s in 1DPC 1R configuration. Populating all four slots reduces the native ceiling to 4800MT/s and the OC headroom to 6533MT/s. Intel XMP 3.0 profiles simplify memory tuning for compatible kits.

PCIe 5.0 M.2 and Thunderbolt 4 Upgrade

The board adds a PCIe 5.0 x16 slot and a CPU-attached Gen5 M.2 socket at 128 Gb/s alongside two Gen4 M.2 sockets at 64 Gb/s. Four SATA 6Gb/s ports and RAID 0, 1, 5, 10 support cover both NVMe and SATA arrays. Rear I/O includes HDMI, DisplayPort and two Thunderbolt 4 Type-C connections. Realtek ALC897 with Nahimic Audio handles 7.1 channel output.

Questions about this item

Will my DDR5-6000 kit run at its rated speed with four sticks installed?

With four single-rank modules the board supports up to DDR5-6533 overclocked, so a DDR5-6000 kit will run at its rated speed when XMP 3.0 is enabled.

Can I use both the HDMI and DisplayPort outputs at the same time for dual monitors?

Yes, the rear I/O provides one HDMI and one DisplayPort, allowing two displays to be driven from the integrated graphics of a Core Ultra Series 2 processor.

How many NVMe drives can I install without using a PCIe slot adapter?

Three M.2 sockets are provided: one PCIe 5.0 x4 from the CPU and two PCIe 4.0 x4 from the chipset, all supporting 2280 drives.
