M391A1K43BB2-CTDQY - Samsung 8GB DDR4-2666MHz PC4-21300 ECC Unbuffered CL19 288-Pin DIMM 1.2V Single Rank Memory Module

Description

The Samsung M391A1K43BB2-CTDQY is an 8GB DDR4 memory module designed for standard computing needs. Operating at a speed of 2666MHz, it provides reliable performance for everyday tasks, gaming, and general productivity in desktops and entry-level servers. As an Unbuffered DIMM (UDIMM), it directly connects to the memory controller without intermediate buffering, making it suitable for systems where memory capacity is not extremely high and direct signaling is preferred. This module features a 1Rx8 rank configuration, indicating a single rank of memory chips, each containing eight data bits. This configuration is common for standard capacity modules and offers a good balance of performance and cost. Unlike RDIMMs, UDIMMs do not have onboard registers, which can limit the maximum memory capacity a system can support but also results in slightly lower latency for certain operations. With a CAS Latency (CL) of 19, the M391A1K43BB2-CTDQY offers a standard level of responsiveness for DDR4 memory. This module is ideal for users looking to upgrade their existing systems or build new ones that require a straightforward and cost-effective memory solution. It is important to note that this is a non-ECC module, meaning it does not have error-correcting capabilities, making it best suited for applications where data integrity is less critical than in enterprise server environments.
