Product Description
This Lenovo memory module, identified by SKU 4X70S69155, is an 8GB DDR4 Unbuffered DIMM (UDIMM) designed to enhance the performance of compatible Lenovo computing devices. UDIMMs are commonly used in mainstream desktops and workstations where the memory controller can directly address the memory chips without an intermediate register. The module operates at a frequency of 2666MHz, offering a substantial improvement in data throughput compared to older DDR generations. Its CAS Latency of CL19 indicates the number of clock cycles required to access a particular memory column, providing a good balance between speed and latency for everyday computing tasks and moderate multitasking. The 1Rx8 configuration signifies a single-rank module with an x8 data organization per DRAM chip. This module is non-ECC, meaning it does not have built-in error correction capabilities, which is typical for consumer-grade and many business-grade systems. It is a straightforward and cost-effective way to upgrade system memory for improved responsiveness and application performance.
