184-pin memory modules are primarily associated with DDR RAM (both DDR1 and DDR2) configurations used in older desktop computers. These modules are generally larger than their SO-DIMM counterparts and were once the standard for desktop memory in the early 2000s. While not commonly used today, 184-pin modules are still found in older systems, however, these older memory modules provide reliable performance for everyday tasks but lack the speed and bandwidth of modern memory standards like DDR3 and DDR4.
