Product Description
The Samsung M391A4G43MB1-CTD7Y is a 32GB DDR4 Unbuffered DIMM (UDIMM) memory module, intended for use in desktop computers and entry-level servers that support unbuffered memory. UDIMMs are the standard type of RAM for most consumer PCs, offering a direct connection between the memory controller and the DRAM chips. This module operates at a speed of 2666MHz (PC4-21300), providing good performance for a wide range of applications. It features a CAS Latency (CL) of 19, which is a common timing parameter for DDR4 memory. The 2Rx8 organization indicates that it is a dual-rank module, meaning it has two independent sets of memory chips (ranks) on the module. This configuration can sometimes enhance performance by allowing the memory controller to interleave accesses between the ranks, improving efficiency. With a substantial 32GB capacity, this UDIMM is well-suited for memory-intensive tasks such as professional content creation, running multiple virtual machines, complex simulations, or demanding gaming. Its compatibility with standard DDR4 motherboards makes it an excellent choice for upgrading the memory capacity of existing systems or for building new high-performance desktop computers.
