APPLICATION
The PR611-C621 is a high-performance ATX server-grade motherboard built for intensive computing and data centre applications. Supporting both 1st and 2nd Gen Intel® Xeon® Scalable processors on the LGA 3647 socket, it features the Intel® C621 chipset and up to 384GB of ECC-RDIMM DDR4 memory across six DIMM slots, supporting speeds up to 2933 MHz. Designed with enterprise flexibility in mind, it includes rich expansion capabilities: three PCIe x16 slots, three PCIe x8 (shared), and dual M.2 slots for storage and wireless connectivity.
The board offers a wide I/O range with two Intel® I210AT GbE LAN ports, up to six SATA 3.0 connectors, one RS-232 serial port, and a total of 11 USB ports—six USB 3.1 Gen1 and five USB 2.0. A BMC (AST2500) is optionally available for IPMI remote management, and TPM 2.0 support enhances hardware-level security. It supports standard ATX power input and operates in environments from -5°C to 65°C.
Ideal for server deployments, industrial storage, network appliances, and virtualisation workloads, the PR611-C621 delivers enterprise reliability, manageability, and robust I/O in a standard ATX footprint.
