ATX server board for Xeon Scalable

The ASRock Rack SPC621D8-2L2T is an ATX motherboard built around the Intel C621A chipset. It accepts a single LGA 4189 processor from the 3rd Gen Intel Xeon Scalable family. Eight DDR4 slots support RDIMM, LRDIMM, 3DS variants and Intel Optane Persistent Memory 200 series at up to 3200 MHz.

Suits dense compute and storage nodes

Builders who need four full-length PCIe 4.0 x16 slots plus three x8 slots, dual 10 GbE and dual 1 GbE ports, and eight SATA 6 Gb/s connectors will find the I/O coverage sufficient. Systems requiring more than one CPU socket, 10 GbE ports beyond the two provided, or onboard Wi-Fi should evaluate alternative platforms.

Single-socket LGA 4189 constraint

The board only fits one processor in the LGA 4189 socket, so total core count and memory-channel bandwidth are limited to what a single 3rd Gen Xeon Scalable CPU delivers. Multi-socket scaling is not possible on this platform.

Jautājumi par šo preci

Does the SPC621D8-2L2T come with a CPU cooler or mounting hardware, or must those be purchased separately?

The motherboard is sold without a CPU cooler or mounting hardware; both must be sourced separately for the LGA 4189 socket.

Which DDR4 module types and capacities are validated on the SPC621D8-2L2T?

The board supports DDR4 3200 RDIMM up to 64 GB, RDIMM-3DS up to 256 GB, LRDIMM up to 128 GB and LRDIMM-3DS up to 256 GB per DIMM.

How do the PCIe 4.0 x16 slots behave when the adjacent x8 slots are populated?

Slots 7, 5 and 3 automatically drop from x16 to x8 electrical when slots 6, 4 or 2 are occupied.
