HP A3T21AV 128GB Kit (8x16GB) DDR3-1600MHz RDIMM 2Rx4 CL11 Memory

Product Description

The HP A3T21AV is a substantial 128GB memory kit designed to empower high-performance servers and workstations. This kit includes eight 16GB DDR3 Registered DIMM (RDIMM) modules, operating at a robust speed of 1600MHz (PC3-12800). The larger module size (16GB) combined with the quantity (8 modules) allows for significant memory expansion in systems that support it, making it ideal for memory-intensive applications, large databases, and extensive virtualization environments. Each module is configured as 2Rx4 (Dual Rank x4), which means it has two independent banks of memory chips (ranks), each with four data bits per chip. This dual-rank configuration can improve performance by allowing the memory controller to interleave operations between the ranks, effectively increasing bandwidth. The RDIMM format includes onboard registers that buffer address and command signals, reducing the electrical load on the memory controller and enabling higher memory capacities and improved system stability, especially in multi-processor configurations. With a CAS Latency of CL11, these modules offer a good balance of speed and timing. Crucially for enterprise environments, the memory supports ECC (Error-Correcting Code), which automatically detects and corrects single-bit memory errors, thereby enhancing system reliability and data integrity. This 128GB kit is a powerful upgrade for HP systems requiring substantial memory resources to handle complex computations, large datasets, and demanding server workloads.
