Dual-socket Xeon server board

The ASRock Rack SP2C741D16X-2T is an EEB form-factor motherboard built for dual LGA 4677 processors. It supports fourth- and fifth-generation Intel Xeon Scalable CPUs with a thermal design power of 350W each. The Intel C741 chipset manages platform I/O and connectivity. This board targets high-density compute clusters and memory-intensive workloads.

Sixteen DDR5 slots and six PCIe 5.0 x16

Eight DIMM slots per socket accept DDR5 RDIMMs up to 96GB and RDIMM-3DS modules up to 256GB at 5600 MT/s with fifth-generation Xeons or 4800 MT/s with fourth-generation Xeons. Six full-length PCIe 5.0 x16 slots also support CXL 1.1, plus one PCIe 5.0 x8 slot, two MCIO x8 connectors and three OCuLink ports for storage. A single M.2 M-key slot takes 2280 or 22110 drives.

Dual 10GbE and IPMI for rack deployment

Two Intel X710-AT2 ports deliver 10Gbps Ethernet alongside a dedicated IPMI lane driven by an ASPEED AST2600 BMC with iKVM and vMedia. The board fits 12.4-inch by 14-inch EEB chassis and provides VGA, two USB 2.0 ports and a UID button with LED on the rear I/O. Builders needing more than one M.2 slot or onboard SATA beyond the OCuLink options should consider other platforms.

Questions about this item

How much heat must the cooling system remove from each 350W Xeon processor under sustained load?

Each supported Intel Xeon Scalable processor has a Thermal Design Power of 350W, so the cooling solution must dissipate that much heat per socket during continuous operation.

What is the noise and thermal impact of running the dual 10GbE LAN ports at full throughput all day?

The onboard Intel X710-AT2 controller drives two 10GbE RJ45 ports; sustained line-rate traffic will increase chipset and VRM temperatures, requiring adequate chassis airflow to keep fan speeds and noise in check.

Which DDR5 memory modules must I already own to populate the 16 DIMM slots?

You need DDR5 288-pin RDIMM or RDIMM-3DS modules — up to 96GB per RDIMM, 128GB for 2H 3DS, or 256GB for 4H 3DS — with speeds of 5600 MT/s on 5th Gen Xeon or 4800 MT/s on 4th Gen Xeon.
