Product Description
The Hynix HMA81GU7CJR8N-VKT0-AC is an 8GB DDR4 Unbuffered DIMM (UDIMM) memory module, suitable for a range of computing applications including mainstream servers, workstations, and high-performance desktops. It operates at a speed of 2666MHz, providing a good balance of performance and capacity for everyday computing tasks and more demanding workloads. The CAS latency is rated at CL19, which is standard for this speed grade and ensures efficient data access. This UDIMM features a 1Rx8 configuration, meaning it is single-rank with memory chips organized as x8 (eight data bits per chip). This configuration is common for standard DIMMs and offers a good density for general-purpose computing. Unlike RDIMMs, UDIMMs do not have a register chip; they communicate directly with the memory controller, which can offer slightly lower latency in some scenarios but typically supports lower maximum memory capacities per channel compared to RDIMMs. This module is a non-ECC (Error-Correcting Code) memory, meaning it does not have built-in error detection and correction capabilities. While ECC memory is preferred for mission-critical server environments where data integrity is paramount, UDIMMs are widely used in systems where the risk of memory errors is lower or where cost and compatibility with standard chipsets are primary considerations. It operates at the standard DDR4 voltage of 1.2V.
