Product Description
The Dell A0390149 is a 1GB DDR2 Registered DIMM (RDIMM) memory module, designed to provide reliable memory expansion for compatible Dell server and workstation systems. Operating at a speed of 400MHz, this module offers a foundational level of performance suitable for basic operating system functions and less demanding applications. The 1Rx4 configuration signifies a single rank of memory with four chips per data path. As a Registered DIMM, it incorporates onboard registers that buffer address and control signals, reducing the electrical load on the memory controller. This feature is crucial for server stability, allowing for higher memory capacities and improved signal integrity, especially in systems with multiple memory modules installed. This memory module also supports ECC (Error-Correcting Code) functionality, which is vital for maintaining data accuracy and system reliability in server environments. ECC memory can detect and correct single-bit errors, preventing data corruption and system crashes. The CL3 CAS latency ensures efficient data retrieval. The Dell A0390149 is a cost-effective solution for upgrading memory in Dell PowerEdge servers or Precision workstations that require DDR2 RDIMMs.
