Dell A4976359 4GB DDR3-1333MHz RDIMM 2Rx4 CL9 Memory

Product Description

The Dell A4976359 is a 4 Gigabyte (GB) DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module specifically designed for use in Dell server systems. As a Registered DIMM (RDIMM), it incorporates an onboard register chip that buffers the command and address signals between the memory controller and the DRAM chips. This buffering reduces electrical load on the memory controller, allowing for higher memory densities and improved system stability, particularly in multi-processor configurations or when populating many memory slots. This memory module operates at a clock speed of 1333MHz, corresponding to a data transfer rate of PC3-10600. The 2Rx4 designation indicates that it is a dual-rank module utilizing x4 (4-bit wide) DRAM chips. Dual-rank modules can offer performance benefits in certain server workloads by allowing the memory controller to access different ranks independently, effectively doubling the bandwidth available to the controller for a given clock cycle. The CAS Latency (CL) of 9 signifies the number of clock cycles required to access data after a command is issued. Furthermore, the A4976359 supports Error-Correcting Code (ECC) functionality. ECC memory can detect and correct single-bit errors in real-time, significantly enhancing data integrity and system reliability, which is critical for server environments where data accuracy and uptime are paramount. Operating at a standard voltage of 1.5V, this module is compatible with DDR3-enabled Dell servers that support RDIMMs.
