Product Description
This 32GB DDR4 Unbuffered DIMM (UDIMM) from Samsung, model M391A4G40MB1-CTD00, is a standard memory module suitable for a wide range of server and workstation applications. It operates at a speed of 2666MHz (PC4-21300), providing good performance for everyday computing tasks and moderate workloads. As an Unbuffered DIMM, it does not have onboard registers like RDIMMs. This makes UDIMMs generally less expensive and suitable for systems that do not require the highest memory densities or extreme stability under heavy load. The 2Rx8 configuration signifies a dual-rank module using x8 DRAM chips, offering a balance of capacity and performance for typical computing needs. With a CAS Latency (CL) of 19, this DDR4 module is designed for reliable operation. While UDIMMs themselves are not always ECC, many server platforms that use UDIMMs support ECC functionality through the memory controller. This module is a cost-effective choice for upgrading memory in compatible systems where high-capacity, registered memory is not strictly required.
