Description
The Samsung M391A1K43BB2-CTDDY is an 8GB DDR4 Unbuffered DIMM (UDIMM) memory module. UDIMMs are commonly used in desktop computers and some entry-level servers. Unlike RDIMMs, UDIMMs do not have a register to buffer commands, making them simpler and generally less expensive, but typically supporting lower total memory capacities per channel. This module operates at a speed of 2666MHz (PC4-21300), providing good bandwidth for everyday computing tasks and applications. This memory module features a 1Rx8 configuration, indicating it is single-rank with x8 memory chips. Single-rank modules are standard for many consumer and business systems. The CAS Latency (CL) is 19, which specifies the delay in clock cycles from when the memory controller requests data from a particular column until the data is available. This speed is typical for DDR4 modules at this frequency. It is important to note that this is a non-ECC (Error-Correcting Code) memory module. Non-ECC memory does not have the built-in error detection and correction capabilities found in ECC memory, making it suitable for applications where data integrity is less critical or where the motherboard does not support ECC. This Samsung UDIMM is a suitable choice for upgrading memory in compatible desktop PCs and entry-level servers.
