If your computer requires that you install memory in pairs, it doesn't matter if the two memory modules are the same type, size,

monitta

Answer:

False

Explanation:

If your computer requires that you install memory in pairs you should always keep in mind that

1. Both are the same type(DDR4+DDR4, DDR3+DDR3, DDR2+DDR2...)

2. Both are the same size (2GB+2GB, 4GB+4GB, 8GB+8GB...)

3. Both are the same speed (800MHz+800MHz, 1666MHz+1666MHz, 3200MHz+3200MHz...)

This is important, because of the predefined slots that are located on the Motherboard.

Although you can change the RAM speed from the BIOS you can not change the predefined slot values
