The ASRock Rack C246M WS is a Micro ATX workstation/server motherboard for Intel Xeon E-2100 and E-2200 processors, suited to compact builds that need ECC memory support, up to 64GB of RAM, and multiple expansion slots.
Recommended For
- Small-workstation builders running compatible Xeon E processors who need ECC memory for CAD, digital imaging, or media-creation workloads in a Micro-ATX system.
- DIY NAS or small-server builders who want several directly attached SATA drives, ECC UDIMM support, and dual Gigabit Ethernet in a compact build they can manage locally.
- Compact workstation builders who need multiple PCIe cards, such as a graphics card plus another expansion card, and can plan around the board’s slot-lane sharing.
