Dual-socket LGA 4677 server board

The ASRock Rack SP2C741D16-2T is an EEB form-factor motherboard built for two 4th or 5th Gen Intel Xeon Scalable processors. Sixteen DDR5 288-pin slots support up to 4 TB of registered memory at 5600 MT/s. The Intel C741 chipset provides the platform foundation.

Suited for dense compute and storage clusters

This board targets builders who need maximum PCIe 5.0 lane count and CXL 1.1 connectivity in a dual-socket layout. Five x16 slots, one x8 slot, two MCIO x8 ports and three OCuLink ports give extensive expansion for accelerators, networking or storage. Buyers who require single-socket operation or smaller ATX footprints should consider other platforms.

Build integration notes

Each CPU can draw up to 350 W, so cooling and power delivery must be planned accordingly. Dual 10 GbE ports and an Aspeed AST2600 BMC handle out-of-band management and high-speed networking. A single M.2 M-key slot accepts 2280 or 22110 modules. The rear I/O supplies video, two USB 2.0 ports and the LAN connections.

Questions about this item

What 4th or 5th Gen Intel Xeon Scalable processors does the LGA 4677 socket support?

The dual LGA 4677 sockets accept 4th and 5th Gen Intel Xeon Scalable processors up to 350 W TDP, including models such as 8580, 8490H, 6548Y+, 5520+, 4514Y and 4410Y.

Can I keep my existing DDR5 5600 RDIMM or RDIMM-3DS modules when upgrading to this board?

Yes, the 16 DDR5 288-pin slots run at DDR5 5600 and support registered RDIMM and RDIMM-3DS modules for up to 4 TB total capacity.

How do I confirm the ASpeed AST2600 video and dual Intel X710-AT2 10 Gbps LAN are active after assembly?

Connect a monitor to the D-Sub port and cables to the two RJ45 ports; the AST2600 will display POST output and the X710-AT2 links will show 10 Gbps activity LEDs.
