8. Replace the memory riser assembly by carefully aligning the connectors of the
assembly and the motherboard.
Caution – When you install the memory riser assembly in the next step, tighten
both of the assembly's thumbscrews simultaneously to avoid damaging the
connector.
9. Using your hands, tighten the thumbscrews simultaneously until they are both
finger-tight.
Caution – Do not apply more torque than needed to close the torque-indicator
drivers's gap. If you apply more torque than needed to close the gap, you might
damage the connectors.
10. Using the short leg of the torque-indicator driver, alternately turn each
thumbscrew clockwise one turn at a time. Stop turning each thumbscrew as soon
as the torque indicator driver gap closes.
11. Press straight down on the middle of the top of the memory riser assembly to
ensure that it is firmly seated in the motherboard connector.
12. Using the torque-indicator driver, alternately turn each thumbscrew clockwise
again to ensure that the thumbscrews remained properly torqued after you
pressed downward on the assembly in the previous step.
