32GB DDR4 ECC Registered DIMM, 2666MHz (PC4-21300) Reliable, high-capacity DDR4 memory designed for servers and workstations that require error correcting and registered memory modules. Key benefits Error correction for greater system reliability: ECC Registered design detects and corrects common memory errors, helping protect data integrity during long runtimes and heavy workloads. Large capacity for demanding applications: 32GB per module provides ample memory for virtualization, large in-memory databases, scientific computing, and multitasking professional workflows. Compatible performance for DDR4 platforms: 2666MHz speed and PC4-21300 rating deliver stable, predictable throughput on supported systems. Form factor for enterprise systems: Standard DIMM physical format and registered memory features are suited to server and workstation motherboards that require ECC Registered modules. Important specifications Memory type: DDR4 Capacity: 32GB Speed: 2666MHz Type: ECC REG (Error-Correcting Code Registered) Form factor: DIMM PC rating: PC4-21300 Condition: 90% new, tested for quality assurance Compatibility and installation Requires a motherboard and processor that support DDR4 ECC Registered memory. Not compatible with standard consumer non-registered DIMM slots that do not accept registered modules. Check system documentation or vendor specifications to confirm support for ECC Registered DIMMs and the supported memory speeds and capacities before installation. Practical use scenarios Virtualization host: Use as system memory in a small to medium scale virtual machine host to support multiple guest systems with improved stability. Database and file servers: Provide larger memory pools and error correction for database caching and file serving environments where uptime and data integrity matter. Professional workstation: Support 3D rendering, video editing, and large dataset processing on workstations that accept ECC Registered memory to minimize interruptions during long render or compute jobs. Additional notes Each module is tested for quality assurance and offered in 90% new condition. Slight color differences from images may occur due to lighting and screen settings. Allow minor dimension variation due to manual measurement.
