Question

A DDR4 DIMM with a PC rating of PC₄-17000 is running at what speed?

1) 1800 MHz
2) 2000 MHz
3) 2133 MHz
4) 3000 MHz

Answer 1

A DDR4 DIMM with a PC rating of PC₄-17000 is running at 2133 MHz.

Step-by-step explanation:

A DDR4 DIMM with a PC rating of PC₄-17000 is running at 2133 MHz.

The PC rating of DDR memory modules indicates the maximum data transfer rate they can achieve. The PC₄-17000 rating corresponds to a transfer rate of 17000 megabytes per second (MB/s). To convert this rating into a frequency in MHz, we divide the transfer rate by 8 (since a byte is composed of 8 bits) and by 2 (since DDR memory is double data rate, meaning it transfers data on both the rising and falling edges of the clock signal).

Therefore, the running speed of the DDR4 DIMM with a PC rating of PC₄-17000 is 2133 MHz.
