Chapter 3, Problem 12TC
Explanation of Solution
Given:
The DIMM rated at PC4 24000.
To find:The speed of the DIMM rated at PC4 24000 in MHz.
Solution:
The speed of a DIMM at a rate of PC4 24000 is 3000 MHz. The speed of a DIMM rated at PC4 24000 is calculated by dividing the PC rating by 8 bytes...
