Question 5

4 steps to install RAM?

3.2 Given a scenario, install the appropriate RAM

Answer 5

1. Orient RAM
2. Insert RAM to slot
3. Press down until the retention clips lock
4. Test

Question 6

What happens if 2 different speeds of RAM is installed?

3.2 Given a scenario, install the appropriate RAM

Answer 6

System will underclock RAM speed to the lower of the 2 speeds

(it will run at the lower of the 2 speeds)

i.e. If you add a DDR4 RAM module with a speed of 3200 MHz to a PC with a DDR4 module at a speed of 2400 MHz, the system will run both modules at 2400 MHz

Question 7
