Description
The ATP AP56K72S8BFD5C is a 2GB memory module based on the DDR2 Fully Buffered DIMM (FB-DIMM) standard. This type of memory is characterized by its use of an Advanced Memory Buffer (AMB) chip on the module itself, which serializes and deserializes data. This buffering mechanism significantly reduces the electrical load on the memory controller, enabling higher memory densities and improved scalability in server systems compared to traditional Registered DIMMs. Operating at a speed of 533MHz (PC2-4200), this FB-DIMM provides a solid performance level for its generation. The CAS Latency (CL) of 4 indicates the number of clock cycles it takes for the memory to respond to a column address command. The 2Rx8 configuration means the module is dual-ranked, with each rank consisting of x8 (8-bit wide) DRAM chips. This configuration can contribute to increased memory bandwidth by allowing the memory controller to interleave accesses between ranks. The standard operating voltage for DDR2 FB-DIMMs is 1.8V. These modules were commonly used in servers and high-end workstations during the DDR2 era to achieve higher memory capacities and improved system stability. The ATP AP56K72S8BFD5C is suitable for upgrading or populating memory in compatible server platforms that require FB-DIMM technology for their memory architecture.
