Description
The ATP AP12K72G4BJE6S-F is a 4GB DDR2 Fully Buffered DIMM (FB-DIMM) memory module, engineered for server and workstation environments. This module operates at a frequency of 667MHz, commonly referred to as PC2-5300, providing a balance of performance and capacity for memory-intensive tasks. The CAS latency is set at CL5, which dictates the delay between the memory controller requesting data and the data becoming available. This particular FB-DIMM is configured as 2Rx4, meaning it is a dual-rank module where each rank uses x4 DRAM chips. The FB-DIMM architecture utilizes an Advanced Memory Buffer (AMB) chip on each module to serialize data transfers, reducing electrical loading on the memory bus and enabling higher memory densities and speeds. This design is crucial for systems that require large amounts of RAM, such as servers running multiple virtual machines or handling complex databases. As a DDR2 FB-DIMM, the AP12K72G4BJE6S-F is designed for compatibility with motherboards and chipsets that specifically support this type of memory. It is a reliable choice for upgrading or expanding the memory capacity of compatible servers and workstations, ensuring smooth operation of demanding applications and multitasking workloads.
