Description
The Hynix HMT42GR7CMR4C-G7D3-AC is a high-capacity 16GB DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module. Engineered for server and workstation environments, this module operates at a frequency of 1066MHz, providing efficient data throughput for demanding computational tasks. Its Registered DIMM (RDIMM) architecture helps to alleviate the electrical load on the memory controller, enabling systems to support larger memory configurations and maintain stability under heavy workloads. This memory module incorporates Error-Correcting Code (ECC) functionality, which is critical for maintaining data integrity in mission-critical applications. ECC detects and corrects single-bit errors on the fly, preventing data corruption and system crashes that can occur with unbuffered memory. The CAS Latency (CL) of 7 indicates the number of clock cycles required to access data, contributing to the module's overall responsiveness and performance. Specified as 4Rx4, this module is a Quad Rank configuration with a data width of x4 per rank. This design enhances memory density and bandwidth, making it suitable for memory-intensive applications such as virtualization, large-scale databases, scientific simulations, and high-performance computing. The Hynix HMT42GR7CMR4C-G7D3-AC is a reliable choice for upgrading or populating servers that require robust and high-performance memory solutions.
