Description
This HP P9A76AR memory kit offers a significant boost in system memory, consisting of four 64GB DDR4 Load-Reduced DIMMs (LRDIMMs). LRDIMMs are crucial for high-density memory configurations as they employ a memory buffer chip to isolate the memory controller from the DRAM devices, reducing electrical load and enabling more memory modules to be installed per channel. The kit operates at a speed of 2133MHz, also known as PC4-17000, providing ample bandwidth for demanding enterprise workloads. The 4Rx4 configuration signifies that each module has four ranks, with each rank having a 4-bit data interface, optimized for server environments requiring high capacity and reliability. With a CAS Latency of CL15, these modules offer a good balance of responsiveness and stability. The inclusion of ECC (Error-Correcting Code) ensures data integrity, a critical feature for servers handling sensitive data or running mission-critical applications. This kit is specifically designed and tested for compatibility with HP ProLiant servers.
