Product Description
The HP B4U17AV is a comprehensive 24GB memory kit designed to significantly enhance the performance and capacity of compatible servers and workstations. This kit comprises twelve individual 2GB DDR3 Unbuffered DIMM (UDIMM) modules, providing a substantial memory upgrade. The DDR3 technology offers improved bandwidth and lower power consumption compared to previous generations, while the 1333MHz speed (also known as PC3-10600) ensures rapid data transfer rates essential for demanding applications and multitasking. Each 2GB module in the B4U17AV kit features a CAS Latency (CL) of 9, indicating the number of clock cycles required for the memory to respond to a command. This timing is standard for DDR3-1333MHz memory and contributes to efficient system operation. The 2Rx8 organization signifies that each module is dual-ranked, with each rank utilizing x8 data width DRAM chips. Dual-rank modules can offer performance benefits in certain system architectures by allowing the memory controller to access data from different ranks more efficiently. Furthermore, these memory modules support ECC (Error-Correcting Code) functionality. ECC memory is crucial in server and workstation environments as it can detect and correct common data corruption errors, thereby enhancing system stability and data integrity. The UDIMM form factor is typically used in non-ECC or registered ECC environments, but these specific modules are noted as ECC capable, indicating their suitability for systems that require error correction for critical operations. This kit is a robust solution for upgrading memory in compatible HP systems.
