Description
The Hynix HMA81GU7DJR8N-VK is an 8GB DDR4 Unbuffered DIMM (UDIMM) memory module, suitable for a variety of computing applications including servers and high-performance desktops. It operates at a speed of 2666MHz, providing efficient data transfer rates for common computing tasks. Unlike RDIMMs, UDIMMs do not have onboard registers; they send command and address signals directly to the DRAM chips, which can offer slightly lower latency in some scenarios but typically support lower overall memory capacities per channel compared to RDIMMs. This module is configured as 1Rx8, indicating it is single-rank with eight data bits per DRAM chip. A key feature of this UDIMM is its support for ECC (Error-Correcting Code) functionality. While ECC is more commonly associated with RDIMMs, its inclusion in this UDIMM provides enhanced data integrity, making it suitable for applications where data accuracy is critical, such as in certain server configurations or professional workstations that require error checking but may not support RDIMMs. With a CAS Latency (CL) of 19, the HMA81GU7DJR8N-VK offers a standard performance profile for DDR4 memory. It is designed for compatibility with systems that support DDR4 UDIMMs, providing a reliable option for users seeking to upgrade their system's memory capacity and benefit from error correction capabilities.
