Description
The ATP AB28L72U4SQB0S is a 1GB memory module engineered for demanding computing environments such as servers and high-performance workstations. It utilizes DDR (Double Data Rate) SDRAM technology, operating at a frequency of 266MHz, which corresponds to the PC2100 standard. This speed offers a significant improvement over older SDRAM generations, enabling faster data access and processing. This module is a Registered DIMM (RDIMM), which means it incorporates a register chip that buffers command and address signals. This buffering reduces electrical load on the memory controller, allowing for more memory modules to be installed in a system and improving overall stability, especially in multi-processor configurations. RDIMMs typically also support ECC (Error-Correcting Code) functionality, which detects and corrects single-bit errors, crucial for data integrity in critical applications. The 2Rx8 designation indicates a dual-rank configuration with eight memory chips per rank. This arrangement can enhance performance by allowing the memory controller to access different ranks concurrently. With a CAS Latency (CL) of 2.5, this module provides a balance between speed and timing, suitable for a wide range of server applications requiring dependable memory performance.
