What is the approximate bus speed of DDR2 memory rated at PC2-5300?

333 MHz Explanation DDR2 memory rated at PC2-5300 has a bus speed of 333 MHz and an internal frequency of 667 MHZ (or DDR2-667). The bandwidth is around 16 times the bus speed and 8 times the DDR- designation. for DDR2, the PC2- designation identifies the bandwidth instead of a number derived from the bus speed. For DDR, DDR2, DDR3, and DDR4 the number following the DDR-designation is always twice that of the bus speed, specifying that the double data rate memory transfers double the data in a single clock cycle. This means that DDR2-667 has a bus frequency (speed) of 333 MHz.

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

Assuming the same operating frequency, what are the advantages of DDR3 over DDR2?

DDR3 doubes the data transfer rate of DDR2. DDR3 uses less power than DDR2. Explanation DDR3 doubles the data transfer rate of DDR2 and generally requires less voltage than DDR2 memory. DDR3 accepts eight consecutive 64-bit words per bus clock cycle, not four as found in DDR2. Both DDR2 and DDR3 memory includes a buffer between the data bus and the memory.

Which of the following memory ratings identifies the fastest memory?

DDR3-1600 Explanation DDR3-1600 has the fastest memory rating. It has a bus frequency of 800 MHz and bandwidth of 12800 MB/s. For DDR, DDR2, DDR3, and DDR4, the number following the DDR designation is always twice that of the bus speed, specifying that the double data rate memory transfers double the data in a single clock cycle. This means that DDR2-667 has a bus frequency of 333 MHz. The older PC designation identified the bus frequency, so PC-133 has a frequency of 133 MHz. The newer PC- designation identifies the bandwidth, so PC-2700 has a bandwidth of 2700 MB/s. To get the frequency from the bandwidth, divide the bandwidth by 16, giving you 166 MHz for PC-2700 and 200 MHz for PC-3200.

Which memory rating identifies the fastest memory?

DDR3-2000 Explanation DDR3-2000 has the fastest memory rating. It has a bus frequency of 1000 MHz and a bandwidth of 16000 MB/s. For DDR, DDR2, DDR3, and DDR4, the number following the DDR-designation is always twice that of the bus speed, specifying that the double data rate memory transfers double the data in a single clock cycle. This means that DDR-400 has a bus frequency of 200 MHz. The newer PC-designation (used with all DDR2 and DDR3 memory) identifies the bandwidth, so PC3-8500 has a bandwidth of 8500 MB/s. To get the frequency from the bandwidth, divide the bandwidth by 16, giving you 533 MHz for PC3-8500 and 667 MHz for PC3-10600.

Assuming the same operating frequency, what are the advantages of DDR4 over DDR3?

DDR4 doubles the data transfer rate of DDR3. DDR4 uses less power than DDR3. Explanation DDR4 doubles the data transfer rate of DDR3 and generally requires less voltage than DDR3 memory. DDR4 accepts eight consecutive 64-bit words per bus clock cycle, the same as found in DDR3. Both DDR3 and DDR4 memory includes a buffer between the data bus and the memory.

Which of the following are terms used to identify memory modules?
