The HP 500203-061 is a DDR3 1333 Module that operates at a frequency of 1333MHz, designed for use in computing systems that require high-speed data processing and reliability. With a specification of DDR3-1333 512Mx72 ECC Reg/RDIMM 2Rx4, it offers a capacity of 4GB, making it suitable for enterprise-level servers and workstations where memory density and error-correcting capabilities are critical. The module is outfitted with ECC (Error-Correcting Code) which detects and corrects data corruption, ensuring data integrity and system stability. It uses a Registered DIMM configuration (Reg/RDIMM) which adds a register between the DRAM modules and the system's memory controller to enhance stability in environments where multiple memory modules are installed. Furthermore, its 240pin interface ensures compatibility with a wide range of motherboards designed for DDR3 memory. Manufactured by HP with a configuration of 256Mx4 36 chips, this memory module is engineered to deliver dependable performance and durability for critical system operations.
