Description
The HP B4U37ATR-P is an 8GB DDR3 Unbuffered DIMM (UDIMM) memory module, engineered to enhance the performance of compatible desktop computers and workstations. It operates at a high frequency of 1600MHz, corresponding to the PC3-12800 standard, which allows for faster data transfer rates compared to lower-speed DDR3 modules. This module is Non-ECC, meaning it lacks error-checking capabilities, making it suitable for general-purpose computing where the highest levels of data integrity are not a primary concern. As an Unbuffered DIMM (UDIMM), this memory module features a direct connection between the DRAM chips and the system's memory controller, which is typical for consumer-grade motherboards. This design contributes to lower cost and power consumption. The module has a CAS Latency (CL) of 11, indicating the number of clock cycles required to access data after a command. It utilizes a standard 240-pin interface and operates at the standard DDR3 voltage of 1.5V. The B4U37ATR-P is also configured as Dual Rank. Dual Rank modules contain two independent sets of memory addresses (ranks) on the same module, enabling the memory controller to switch between them. This can potentially improve performance by reducing wait times and increasing the efficiency of memory access. With its 8GB capacity and high speed, this DDR3 UDIMM is an excellent choice for upgrading systems to improve multitasking, application responsiveness, and overall computing experience.
