Product Description
The HP PQ1437 is a high-performance memory module designed to upgrade or expand the RAM in compatible computing systems. This module features 4GB of DDR3 SDRAM, operating at a speed of 1600MHz, which translates to a PC3-12800 designation. The inclusion of ECC (Error-Correcting Code) technology is crucial for maintaining data integrity, as it detects and corrects single-bit errors, making it ideal for servers, workstations, and other mission-critical applications where stability is paramount. This memory module is classified as Unbuffered, meaning it does not have an onboard register to buffer commands and addresses. This typically results in lower latency and power consumption compared to registered (RDIMM) modules, making it suitable for systems that can directly handle unbuffered memory. The module is also Dual Rank (2R), which can offer performance benefits in certain system architectures by allowing the memory controller to access different sets of memory chips simultaneously. With a CAS Latency (CL) of 11, the PQ1437 strikes a balance between speed and stability. This 4GB DDR3 UDIMM is a reliable component for enhancing system responsiveness, improving multitasking capabilities, and ensuring smooth operation of demanding software applications. Its specifications make it a suitable choice for upgrading systems that support DDR3 memory with ECC and unbuffered configurations.
