ASRock Rack SP2C621D16-2T EEB server motherboard dual LGA 4189 8+8 DDR4 3200

Dual LGA 4189 server board for 3rd Gen Xeon

The ASRock Rack SP2C621D16-2T is an EEB form-factor motherboard built around the Intel C621A chipset. It accepts two 3rd Gen Intel Xeon Scalable processors in LGA 4189 sockets and provides sixteen DDR4 3200 DIMM slots in a 1DPC layout. Five PCIe 4.0 x16 slots and one x8 slot deliver high-bandwidth expansion for compute accelerators or networking cards. Dual 10 GbE ports driven by an Intel X550-AT2 controller handle heavy data traffic.

Suited for dense virtualization and storage nodes

This board targets builders who need dual-socket performance with abundant memory capacity and fast networking. The fourteen SATA 6.0 Gb/s ports and two SlimSAS connectors support large drive arrays without add-in HBAs. Buyers who require more than one M.2 device or who need integrated Wi-Fi should look at alternative platforms. Systems that must fit in standard ATX chassis cannot use the 12 x 13 inch EEB outline.

Sixteen DDR4 3200 slots in 1DPC configuration

Memory capacity tops out at sixteen modules running at 3200 MT/s, with each channel populated by a single DIMM for signal integrity. RDIMM, LRDIMM and Intel Optane persistent memory are all supported. This density decides whether the platform can hold the working set for in-memory databases or large VM fleets.
