Deep Micro-ATX Server Motherboard

The ASRock Rack SPC741D8UD-2T/X550 is a Deep Micro-ATX server motherboard built for single-socket Intel Xeon Scalable processors. It uses the LGA 4677 socket and Intel C741 chipset. The board targets dense 1U or 2U systems needing high core counts and fast I/O.

Suits high-density compute nodes.

This board suits builders assembling high-density compute or storage nodes with a single 350 W TDP processor. It is not for deployments that require dual-socket scaling or more than four full-length PCIe 5.0 x16 add-in cards.

Four PCIe 5.0 x16 slots with CXL 1.1

The defining specification is four PCIe 5.0 x16 slots that also support CXL 1.1, all wired directly to the CPU. This layout decides whether the board can host the GPU, accelerator or high-speed NIC complement your workload demands.

Questions about this item

What chassis clearance does the 10.4 x 10.5 inch Deep Micro-ATX board need?

The board fits a Deep Micro-ATX layout measuring 10.4 by 10.5 inches; verify the chassis supports this exact footprint and the LGA 4677 socket keep-out zone before mounting.

Which CPU power limit must the cooler handle during installation?

Install a cooler rated for the 350 W thermal design power of the supported Xeon processors; the common mistake is using a lower-TDP heatsink that cannot dissipate the full load.

What maximum RDIMM-3DS capacity per slot should I plan for future upgrades?

Each DDR5 slot accepts up to 256 GB RDIMM-3DS (4H) modules, allowing a total of 2 TB across the eight 288-pin slots when populated with supported Xeon CPUs.
