The ASRock Rack B650D4U3-2L2Q/BCM is a Micro-ATX server motherboard for AMD EPYC 4004/4005 and Ryzen 7000/8000/9000 processors, suited to compact servers that need dual 25GbE SFP28 networking and remote IPMI management.
Recommended For
- Homelab and Proxmox builders who want a compact AM5 server with out-of-band IPMI management and dual onboard 25GbE links for fast host or storage networking.
- Small-server operators choosing a supported EPYC 4004/4005 or Ryzen processor who need ECC UDIMM support, remote KVM/media management, and a Micro-ATX board.
- Self-hosters or storage-server builders whose network already uses SFP28 and who want two onboard 25GbE ports without using the main PCIe x16 slot for a network card.
- Compact workstation builders who need one PCIe 5.0 x16 slot for a GPU or accelerator, server-style remote management, and an AM5 CPU platform.
