Dell A7278301 4GB DDR3-1333MHz RDIMM 2Rx4 CL9 Memory

Product Description

The Dell A7278301 is a 4GB Registered Dual In-line Memory Module (RDIMM) specifically designed for use in server and workstation environments. This module utilizes DDR3 SDRAM technology, operating at a clock speed of 1333MHz, which corresponds to a PC3-10600 designation. The RDIMM form factor includes an onboard register that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in systems with multiple memory modules. This memory module features a 2Rx4 configuration, indicating it is dual-ranked with each rank utilizing x4 (4-bit-wide) DRAM chips. Dual-rank modules can offer performance benefits in certain scenarios by allowing the memory controller to access data from different ranks concurrently. The CAS (Column Access Strobe) latency is rated at CL9, which specifies the number of clock cycles required to access data in a column. Lower CAS latency generally translates to faster memory performance. Furthermore, the A7278301 incorporates ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, significantly enhancing data integrity and system reliability, which is crucial for mission-critical applications running on servers and workstations. This 4GB DDR3-1333MHz RDIMM is a standard component for upgrading or populating memory in compatible Dell servers and other enterprise-grade systems.
