Product Description
The ATP AL12P72L8BKH9S is a 4GB DDR3 Registered DIMM (RDIMM) memory module, engineered to enhance the performance and stability of server and workstation systems. Operating at a frequency of 1333MHz, this module provides a significant boost in data processing capabilities compared to lower-speed memory. The Registered DIMM architecture 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 system stability, which is crucial in demanding server environments. This memory module features a CAS Latency (CL) of 9, indicating the number of clock cycles it takes for the memory to respond to a column address command. The 2Rx4 configuration signifies that the module is dual-ranked, with each rank composed of x4 (4-bit wide) DRAM chips. Dual-rank modules can offer performance advantages in certain scenarios by allowing the memory controller to interleave access between ranks, effectively increasing bandwidth. This configuration is common in enterprise-grade memory solutions. As an RDIMM, the AL12P72L8BKH9S typically supports ECC (Error-Correcting Code) functionality, which is vital for detecting and correcting single-bit memory errors, thereby preventing data corruption and system crashes. This makes it an ideal choice for mission-critical applications where data integrity and system uptime are paramount. The 4GB capacity is suitable for a wide range of server configurations, providing a solid foundation for multitasking and running memory-intensive applications.
