U143D Dell 4GB DDR3 1066MHz CL7 ECC Registered RDIMM Memory

The Dell U143D is a 4GB DDR3 memory module designed for use in servers and workstations. It operates at a frequency of 1066MHz with a CAS Latency of 7, providing a balance of speed and timing for system memory operations. This module is equipped with ECC functionality, which helps detect and correct internal data corruption to maintain system reliability.

The registered DIMM (RDIMM) design adds an additional register between the DRAM modules and the system memory controller, improving signal integrity and stability when multiple DIMMs are used.

• 4GB DDR3 capacity suitable for moderate memory requirements
• 1066MHz operating speed with CL7 latency for data timing
• ECC support to enhance data reliability in critical applications
• Registered DIMM architecture for stable multi-DIMM configurations
• Designed by Dell to meet compatibility standards for Dell systems

This memory module plays a crucial role in maintaining system stability and data integrity in Dell server environments. Its ECC and registered design make it suitable for workloads where error detection and correction are critical to operation. It offers a practical memory upgrade path for compatible Dell systems requiring 4GB DDR3 modules at 1066MHz.
