COMPTIA A+ Practice Exam

Which technology supports DDR2 memory?

1. AM2

2. AM3

3. Hyper-threading

4. EDB

The correct answer is: AM2

The reason AM2 is the correct answer is that it is a CPU socket designed by AMD specifically to support DDR2 memory. The AM2 socket was introduced in 2006 to accommodate the newer generations of AMD processors that required DDR2 memory for improved performance and bandwidth compared to its predecessor, DDR. This socket allows for a direct electrical connection to the memory module, effectively enabling the CPU to leverage the advantages of DDR2 technology, such as faster speeds and lower power consumption. Since DDR2 was a popular memory standard during the era of the AM2 socket, this connection was essential for the proper functioning of compatible processors. In contrast, AM3, introduced later, is designed to support both DDR2 and DDR3 memory but is not limited to DDR2 alone. Hyper-threading, which is a technology developed by Intel, refers to the ability of a CPU to act like multiple separate processors to the operating system, thereby improving performance in multi-threaded applications; it does not directly relate to memory support. EDB, which stands for Enhanced Data Out, is associated with memory performance and I/O operations but does not define a memory type or socket standard. Thus, AM2 is specifically tailored for DDR2 memory compatibility, making it the correct choice
