Product Description
The Dell 0HWTT1 is a 2GB DDR2 Fully Buffered DIMM (FB-DIMM) memory module, specifically designed for server platforms that require the DDR2 memory standard. Operating at a frequency of 667MHz, this module offers a capacity boost for systems that may be nearing their memory limits, enabling better performance for memory-intensive applications and increased virtual machine density. The 2Rx8 configuration signifies a dual-rank module, where each rank consists of eight memory chips. Dual-rank modules can sometimes offer performance advantages by allowing the memory controller to access different ranks concurrently. The CL5 CAS latency is characteristic of DDR2 memory operating at this speed, providing a reasonable balance for the technology generation. FB-DIMMs incorporate an Advanced Memory Buffer (AMB) chip, which buffers both command/address and data signals, reducing the electrical load on the memory controller and enabling higher memory capacities per channel compared to standard unbuffered DIMMs. This module also includes ECC (Error-Correcting Code) capabilities, which are essential for server environments to maintain data integrity and system stability by detecting and correcting memory errors. The use of FB-DIMMs was prevalent in servers during the DDR2 era, offering a path to higher memory configurations before the advent of DDR3. This specific module is suitable for upgrading or populating memory in compatible IBM, Dell, HP, and other server systems that support DDR2 FB-DIMMs.
