Which type of RAM should you install if your motherboard has sockets for 184-pin DIMM RAM?

1. DDR1

2. DDR2

3. DDR3

4. SDRAM

The correct answer is: DDR2

The correct choice for a motherboard that has sockets for 184-pin DIMM RAM is DDR2. DDR2 (Double Data Rate 2) RAM uses a 240-pin design but has versions adapted for 184-pin sockets, specifically the DDR1 (or DDR SDRAM). This is critical in understanding the transition from DDR1 to DDR2 technology, as they both share the same physical dimensions in terms of pin count. DDR2 offers improvements over DDR1, including higher bandwidth and reduced power consumption, making it a more efficient choice for performance and energy use. This evolution between RAM types is essential knowledge, especially when considering compatibility with a motherboard's specific configurations. The distinction between these RAM types lies in their architecture. DDR1 still functions in the same 184-pin sockets but lacks the enhancements that DDR2 brings. On the other hand, DDR3 uses a different 240-pin configuration that would not fit into a 184-pin socket. SDRAM (Synchronous Dynamic RAM) is an older technology that relates to RAM types but does not specifically denote the pin configuration relevant to the question. In summary, DDR2 RAM is the appropriate choice for compatibility with a motherboard featuring 184-pin DIMM sockets, as it maintains compatibility with those
