DDR had twice the throughput of SDRAM at the same system clock speed due to the ability to clock two words per clock cycle, one on the rising edge and one on the falling edge of the clock. DDR2 doubles the throughput of DDR by _____.

Clock doubling the input/output circuits on the chips within the DDR2 module

Doubling the width of the data bus from 32 bits to 64 bits

Doubling the buffer size used by DDR

Increasing the voltage used

DDR3 increased the throughput from that of DDR2 by _____.

Clock doubling the input/output circuits on the chips within the DDR3 module

Doubling the width of the data bus from 64 bits to 128 bits

Doubling the buffer size from that used by DDR2

Increasing the voltage used

Match the voltage to that used by the correct type of RAM.

SDRAM 1.2 V

DDR 1.5 V

DDR2 3.3 V

DDR3 2.5 V

DDR4 1.8 V

In order to take advantage of dual-channel memory, an equal number of modules must be used on each channel and there must be the same amount of memory installed in each channel.
