Description
The Samsung M391A4G43MB1-CTDQY is a 32GB DDR4 Unbuffered DIMM (UDIMM) memory module, designed for mainstream desktop computers and some entry-level servers. UDIMMs do not have a register chip, meaning command and address signals are sent directly to the DRAM chips, which can limit the maximum memory capacity and speed compared to RDIMMs. This module operates at 2666MHz (PC4-21300), a common speed for DDR4 memory. It features a CAS Latency (CL) of 19, defining the timing for data access. The 2Rx8 organization indicates a dual-rank configuration, where the memory module has two independent sets of memory chips (ranks) that the memory controller can access. This dual-rank design can sometimes offer performance benefits in systems that support it, particularly in multitasking scenarios. With a substantial 32GB capacity, this UDIMM is suitable for users who require significant memory for tasks such as gaming, video editing, running virtual machines, or handling large datasets. Its compatibility with standard desktop motherboards and systems that support DDR4 UDIMMs makes it a versatile option for memory upgrades.
