A PC technician must upgrade memory from 2 GB to 4 GB in twenty Windows 7 notebook
computers. Some of the laptops have DDR2 memory, and some have DDR3. The memory
purchased for the upgrade is DDR3.
Which of the following is the MOST likely outcome of this upgrade?
A.
The DDR2 notebooks will work with DDR3 provided the DDR2 is installed in the first
DIMM positions.
B.
The DDR3 notebooks are the only ones that will accept the new memory.
C.
The DDR2 memory will fit into the DIMM positions and work.
D.
The DDR3 memory will not work correctly unless the CAS (CL) values are the same.
Explanation:
A DDR3 memory can only work with other DDR3 chips. It cannot work with DDR2.
Therefore, the DDR3 memory purchased can only be used to upgrade notebook computers
that have DDR3 memory installed.
