Description
The Dell 370-17561 is a high-capacity 8GB memory module specifically designed for server and enterprise environments. It utilizes DDR3 SDRAM technology, operating at a clock speed of 1066MHz, which translates to a bandwidth of PC3-8500R. The 'R' in PC3-8500R signifies that it is a Registered DIMM (RDIMM), a crucial feature for server memory as it includes an onboard register to buffer command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and greater stability. The module's 4Rx4 configuration indicates a quad-rank design, where the memory is divided into four groups (ranks), and each rank uses x4 (4-bit) data width chips. This configuration can offer performance benefits in certain workloads by allowing the memory controller to access different ranks concurrently, improving efficiency. Furthermore, as an RDIMM, it inherently supports ECC (Error-Correcting Code) functionality, which detects and corrects single-bit memory errors, vital for maintaining data integrity in critical server operations. With a CAS Latency (CL) of 7, this module strikes a balance between speed and timing. The 1.5V operating voltage is standard for DDR3 memory. This 8GB DDR3-1066MHz RDIMM is a reliable component for expanding or upgrading the memory in compatible Dell servers or other systems that require registered, ECC-enabled memory with specific rank configurations for optimal performance and stability.
