Dell 00Y9H5 16GB DDR3-1600MHz RDIMM 2Rx4 CL11 Memory

Product Description

This Dell 00Y9H5 memory module is a high-capacity 16GB DDR3 Registered DIMM (RDIMM) designed for enterprise-level servers and workstations that require enhanced stability and performance. The RDIMM form factor includes an onboard register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory densities and speeds. This makes RDIMMs ideal for systems with many memory modules installed. The module operates at a speed of 1600MHz (PC3-12800), providing significantly faster data transfer rates compared to lower-speed DDR3 modules. The 2Rx4 configuration indicates two ranks of memory chips, each with a 4-bit data width, which is common for higher-density RDIMMs. Crucially, this module supports ECC (Error-Correcting Code) functionality, which detects and corrects single-bit memory errors on the fly, thereby improving system reliability and data integrity – a critical feature for mission-critical applications and servers. With a CAS latency of CL11, this module offers a balance between speed and timing. While higher latency than some lower-speed modules, it is appropriate for the 1600MHz speed and RDIMM architecture. This 16GB DDR3 RDIMM is a robust solution for upgrading server memory capacity and performance, ensuring that demanding workloads can be handled efficiently and reliably. Always confirm system compatibility before installation.
