The ASRock Rack D1749NTD4U-4T4O is a Micro-ATX server motherboard with an onboard Intel Xeon D-1749NT processor, four memory slots, and IPMI remote management. It suits compact servers and infrastructure builds that need integrated compute and remote administration.
Recommended For
- Server and storage builders creating a compact NAS or storage server who need multiple 10GbE connections and room to expand SATA storage; the board supports up to 17 SATA drives, with some storage connections sharing lanes.
- Network-appliance builders connecting several 10GbE copper and SFP28 links in one system, such as a lab router, firewall, or network-services server.
- IT teams building a remotely managed server for a rack or equipment room who want IPMI-based management and ECC memory support without a separate add-in management card.
- System integrators building compact Xeon D servers for edge or infrastructure workloads who can use a Micro-ATX board and provide adequate chassis airflow for the 90W processor.
Spec Summary
| Attribute | Value |
|---|---|
| Best For | Single-processor server builds combining Xeon D processing, ECC memory support, and multiport 10Gbps networking |
| Processor And Power | Intel Xeon D-1749NT processor for one CPU; thermal design power up to 90W |
| Memory Configuration | Four 288-pin DDR4 slots supporting DDR4-2666, up to 128GB, with ECC and registered memory support |
| Expansion Slots And Lane Sharing | PCIe 4.0 x16 slot shares lanes with two PCIe 4.0 x8 SlimSAS connectors; a PCIe 3.0 x8 slot shares lanes with two Mini-SAS HD connectors through a BIOS setting. Slot population affects SlimSAS availability |
