The ASRock Rack GENOAD8UD-2T/X550 is a deep Micro-ATX server motherboard for builders creating compact, single-socket systems with AMD EPYC 9004-series processors. It combines eight DDR5 RDIMM slots, four PCIe 5.0/CXL 1.1 x16 slots, and dual 10GbE with remote IPMI management.
Recommended For
- Builders creating a compact EPYC server for virtualization or CPU-parallel workloads who need multiple PCIe cards, dual 10GbE, and out-of-band management.
- TrueNAS or other storage-server builders who want an EPYC platform with many drive connections through MCIO, plus PCIe slots for storage or networking cards.
- Homelab or small-server operators who manage machines remotely and need dual 10GbE for fast local-network traffic without adding a separate network card.
- Workstation builders with software, rendering, or other heavily threaded jobs who specifically need an EPYC 9004/9005-class single-socket platform in a smaller-than-EATX build.
