Lab 3-8: Identify Memory Technologies

How wide is a DIMM's dual-channel data path compared to a single-channel data path? 64 bits instead of 32 bits 128 bits instead of 64 bits 512 bits instead of 256 bits 256 bits instead of 128 bits

128 bits instead of 64 bits A standard single-channel data path is 64 bits. A dual-channel data path is twice that at 128 bits.

What's the difference between DDR3 and DDR3L? A) DDR3L requires less power than DDR3 B) DDR3L is faster than DDR3 C) DDR3L is smaller than DDR3 so it can fit into smaller cases D) DDR3L has the same number of pins as DDR4, not DDR3.

A) DDR3L requires less power than DDR3

Why do we usually put the first memory card in the DIMM slot closest to the CPU? A) This slot uses the shortest bus. B) A DIMM in this slot is less likely to get damaged by cables and other components near the motherboard. C) All these are true D) This slot stays cooler next to the CPU fan.

A) This slot uses the shortest bus.
