Black BD2G400MER14 Diamond 2GB DDR-400MHz RDIMM 2Rx4 CL3 Memory

Product Description

The Black Diamond BD2G400MER14 is a 2GB Registered Dual In-line Memory Module (RDIMM) operating at DDR-400MHz. This type of memory is specifically designed for server and high-end workstation environments where stability, reliability, and the ability to support larger memory capacities are critical. The 'Registered' aspect means the module includes a register chip that buffers address and command signals between the memory controller and the DRAM chips. This reduces the electrical load on the memory controller, allowing for more memory modules to be installed in a system and improving signal integrity, especially at higher speeds. The 2Rx4 organization indicates that the module is dual-ranked, with each rank consisting of memory chips organized as x4 (4-bit wide). This configuration can offer performance advantages in certain server workloads by allowing the memory controller to interleave accesses between ranks. The CAS Latency (CL) is rated at 3 clock cycles, which is a measure of the delay between the memory controller requesting data from a specific column and the data becoming available. DDR-400MHz represents a significant speed for its generation, enabling faster data processing. This RDIMM is built to the stringent standards required for server-grade components, featuring ECC (Error-Correcting Code) functionality. ECC memory can detect and correct single-bit errors on the fly, preventing data corruption and system crashes, which is paramount in mission-critical applications. The BD2G400MER14 is an ideal choice for upgrading or populating memory in compatible servers and workstations that require registered, ECC memory with DDR-400MHz support. Always verify system compatibility with RDIMMs and specific speed/rank configurations.
