Product Description
The Dell A21327981 is an 8GB DDR3 Registered DIMM (RDIMM) memory module, specifically engineered for server and high-end workstation applications where stability and performance are paramount. Operating at a frequency of 1066MHz, this module provides a solid foundation for memory-intensive tasks. The RDIMM form factor includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved signal integrity, especially in systems with many memory modules. This module features a 2Rx4 configuration, meaning it has two ranks, each composed of memory chips with a x4 data width. This configuration is common in enterprise-grade memory and can offer advantages in bandwidth and efficiency for certain server workloads. The CAS Latency (CL) of 7 is relatively low for DDR3, indicating a quick response time to memory requests, which contributes to overall system responsiveness. Crucially, this is an ECC (Error-Correcting Code) memory module. ECC functionality detects and corrects single-bit memory errors, and detects multi-bit errors, significantly enhancing data integrity and system reliability. This makes the A21327981 an ideal choice for critical server environments where data accuracy and uptime are essential, such as in databases, virtualization, and scientific computing.
