ASRock Rack D1749NTD4U-4T4O Xeon D-1749NT server motherboard 4 SFP28 4 RJ45 10GbE

Built-in Xeon D-1749NT for dense 1U builds

This Micro-ATX server motherboard integrates an Intel Xeon D-1749NT processor with a 90W thermal design power. Four 288-pin DDR4 slots accept registered ECC memory up to 128GB at 2666 MT/s. The board targets builders who need high core density in a 9.6-inch square footprint without a separate CPU cooler mount.

Eight 10GbE ports and flexible PCIe lane sharing

The rear I/O provides four RJ45 and four SFP28 connections driven by an Intel X557-AT4 controller, all operating at 10Gbps. A PCIe 4.0 x16 slot shares lanes with two SlimSAS connectors, while a PCIe 3.0 x8 slot can switch to two Mini-SAS HD ports. Two M.2 sockets support 2280 or 22110 drives, with the second M.2 disabling four SATA ports when populated.

Single-socket SoC limits upgrade paths

The soldered Xeon D-1749NT means the processor cannot be replaced or upgraded later. Buyers who want a socketed CPU for future generation swaps or higher core counts must choose a different platform.
