879527-091 - HP 16GB DDR4-2666MHz PC4-21300 ECC Unbuffered CL19 288-Pin DIMM Dual Rank 1.2V Memory Module

Description

The HP 879527-091 is a 16GB DDR4 memory module designed for use in servers and workstations that support Unbuffered DIMMs (UDIMMs). This module operates at a speed of 2666MHz, providing a solid performance baseline for a wide range of computing tasks. DDR4 technology offers improvements in bandwidth and power efficiency over previous generations, making it a standard for modern computing platforms. This UDIMM is characterized by its 2Rx8 configuration, meaning it is dual-ranked and utilizes x8 DRAM chips. Dual-rank modules can sometimes offer a slight performance advantage over single-rank modules by allowing the memory controller to interleave operations between the ranks. The CL19 CAS latency indicates the timing for memory access, which is a common specification for DDR4 modules at this speed. Unlike RDIMMs or LRDIMMs, UDIMMs do not have a register chip and connect directly to the memory controller, which typically limits the maximum memory capacity per channel but can be more cost-effective for certain applications. Importantly, this module is a Non-ECC (Error-Correcting Code) memory module. This means it does not have the built-in error detection and correction capabilities found in ECC memory. While this makes it suitable for many desktop and some entry-level server applications where data integrity is less critical or handled at the application level, it is not recommended for mission-critical server environments that require the highest levels of data reliability. The HP 879527-091 is a standard memory upgrade option for compatible systems seeking increased capacity and performance.
