Product Description
The Dell AB011890 is a high-capacity 64GB DDR4 Registered DIMM (RDIMM) memory module, engineered to deliver robust performance for enterprise-level computing environments. Operating at a speed of 2933MHz, it provides significant bandwidth, crucial for memory-intensive tasks such as virtualization, large database operations, and complex data analytics. This module features a 2Rx4 rank configuration, indicating it is dual-ranked with each rank organized into x4 (four-bit) memory chips. This design can enhance performance by allowing the memory controller to access different ranks independently, improving efficiency. The CL21 CAS latency signifies the number of clock cycles required for the memory to respond to a request, offering a balance between speed and stability for server applications. Designed for compatibility with Dell PowerEdge servers and other compatible systems, the AB011890 ensures reliable operation and data integrity. Its RDIMM form factor includes onboard registers that buffer command and address signals, reducing electrical load on the memory controller and enabling higher memory capacities and speeds. This makes it an ideal upgrade for systems requiring maximum memory performance and stability.
