Product Description
This 4GB DDR RDIMM from ATP, identified by SKU AB12L72P4SMB3S, is a memory module designed for server and workstation environments that utilize DDR memory technology. The RDIMM form factor includes a register chip that buffers command and address signals, reducing the electrical load on the memory controller and enabling higher memory capacities and improved system stability. The module operates at a speed of 333MHz (often referred to as PC2700 in the DDR era) with a low CAS Latency of CL2.5. This combination provides efficient data access for applications that were common during the DDR memory generation. The 4Rx4 organization signifies a quad-rank configuration, where each rank consists of four data chips. Quad-rank modules can offer higher density and potentially improved performance in systems that can fully utilize their capabilities, though they may place a higher load on the memory controller. As a server-grade memory module, it features ECC (Error-Correcting Code) support. ECC memory can detect and correct common types of internal data corruption, which is critical for maintaining data integrity and system reliability in continuous operation environments like servers and workstations. The standard 2.5V operating voltage is characteristic of DDR memory.
