Description
The ATP AB56L72Z4BFB0S is a 2GB Registered DIMM (RDIMM) module, specifically engineered for server and high-performance computing environments. This memory module operates at a speed of 266MHz, which corresponds to the PC2100 standard for DDR SDRAM. The Registered DIMM architecture includes an onboard register that buffers command and address signals, reducing electrical load on the memory controller and allowing for greater memory capacity and stability in systems with many memory modules. This particular module features a CAS Latency (CL) of 2.5, indicating the number of clock cycles required to access data after a command is issued. The 1Rx4 configuration signifies that the module is single-ranked, with four memory chips (or sets of chips) per rank. This configuration is often chosen for its balance of performance and density in server applications. As an RDIMM, it also typically supports Error-Correcting Code (ECC) functionality, which detects and corrects single-bit memory errors, crucial for maintaining data integrity in critical systems. Designed for compatibility with servers and workstations that utilize DDR memory, the AB56L72Z4BFB0S provides a reliable and efficient upgrade or replacement option. Its specifications make it suitable for a wide range of applications, from general server tasks to more demanding workloads that benefit from stable and error-corrected memory. The 2GB capacity, while modest by today's standards, was significant for its time and remains useful in specific legacy or specialized system configurations.
