Description
The HP 5006661-B21 is a high-capacity memory module designed to boost the performance and expand the memory footprint of compatible server systems. This module features 16GB of DDR3 SDRAM, providing ample capacity for running multiple applications simultaneously and handling large datasets. The DDR3 technology represents a significant advancement over previous generations, offering improved power efficiency and higher data transfer rates. Operating at a speed of 1066MHz, this memory module ensures rapid access to data, which is critical for server workloads that demand high I/O performance. The CL7 CAS Latency indicates the number of clock cycles required to access data, with a lower latency generally translating to faster response times. As a Registered DIMM (RDIMM), it includes a register chip that buffers the command and address signals, reducing electrical load on the memory controller and allowing for more memory modules to be installed in a system, thereby increasing overall memory capacity and stability. The 4Rx4 organization signifies that the module is composed of four ranks, with each rank utilizing x4 (4-bit) DRAM devices. This configuration can offer advantages in terms of performance and density. This specific HP memory module is engineered for reliability and compatibility within HP server environments, making it a suitable choice for upgrading existing systems or configuring new ones that require robust and high-performance memory solutions.
