Description
The Lenovo 5458-A3QC is an 8GB DDR3 Unbuffered DIMM (UDIMM) memory module, designed for standard computing platforms such as desktops and workstations. It operates at a speed of 1600MHz, also known as PC3-12800, providing a good balance of performance and compatibility for everyday computing tasks and moderate workloads. The 2Rx8 rank configuration signifies a dual-rank module where each rank has an x8 data organization. Dual-rank modules can offer performance benefits in certain scenarios by allowing the memory controller to access data from different ranks concurrently, potentially improving throughput. The CL11 CAS latency indicates the number of clock cycles required for data access, offering a reasonable response time for general use. Unlike RDIMMs, UDIMMs do not have an onboard register. This makes them suitable for systems with fewer memory slots or where the memory controller can handle the direct load. This specific module is non-ECC, meaning it does not have error-correcting capabilities, which is typical for consumer-grade and many business desktop systems. It is a cost-effective solution for upgrading system memory for improved multitasking and application performance.
