Dell SNP9F035C/4G 4GB DDR2-667MHz FB-DIMM 2Rx4 CL5 Memory

Product Description

The Dell SNP9F035C/4G is a 4GB memory module utilizing DDR2 SDRAM technology, specifically designed in a Fully Buffered DIMM (FB-DIMM) form factor. FB-DIMMs were introduced to overcome the signaling limitations of traditional unbuffered DIMMs (UDIMMs) in high-density memory configurations. They incorporate an Advanced Memory Buffer (AMB) chip on each module, which serializes and deserializes data, allowing for higher clock speeds and greater memory capacities per channel. This particular module operates at a frequency of 667MHz, providing a substantial bandwidth for memory-intensive applications. The 2Rx4 designation signifies that it is a dual-rank module, with each rank consisting of memory chips organized as x4 (four data bits per chip). Dual-rank modules can offer performance benefits in certain system architectures by allowing the memory controller to access different ranks concurrently, effectively increasing the available bandwidth. Designed primarily for server and workstation environments, this FB-DIMM includes Error-Correcting Code (ECC) functionality. ECC memory can detect and correct single-bit errors on the fly, which is crucial for maintaining data integrity and system stability in mission-critical applications. The SNP9F035C/4G is compatible with systems that specifically support the FB-DIMM interface and DDR2 memory speeds, often found in servers from the mid-2000s era.
