Dell 0YT206 4GB Kit (2x2GB) DDR2-667MHz FB-DIMM 2Rx8 CL5 Memory

Product Description

The Dell 0YT206 is a 4GB memory kit designed for systems utilizing DDR2 Fully Buffered DIMM (FB-DIMM) technology. This kit includes two 2GB modules, providing a total of 4GB of high-speed memory. FB-DIMMs were an advancement over standard DIMMs, featuring an Advanced Memory Buffer (AMB) chip on each module that serializes data, allowing for higher densities and speeds while reducing the electrical load on the memory controller. This makes them particularly suitable for demanding server environments. Operating at a frequency of 667MHz (PC2-5300), these modules offer substantial bandwidth for memory-intensive applications. The 2Rx8 configuration indicates dual-rank modules with 8-bit memory chips, which can enhance performance by allowing the memory controller to access different ranks concurrently. The CL5 CAS latency is a measure of the delay in clock cycles for data retrieval. These FB-DIMMs also incorporate ECC (Error-Correcting Code) to detect and correct memory errors, ensuring data integrity critical for server operations. Each module in the Dell 0YT206 kit is equipped with heat spreaders to manage the thermal output generated by the AMB chip and memory components. This is essential for maintaining stability and longevity in densely populated server chassis. The 1.5V operating voltage is standard for DDR2 FB-DIMMs. This kit is an excellent choice for upgrading Dell servers that support DDR2 FB-DIMM memory, offering increased capacity and performance for virtualization, databases, and other enterprise workloads.
