Dropping the Screws into the Aligned Mounting Holes
10. Using your fingers, turn all four screws until they take up just the first one or two
threads in the metal hex standoffs (see
FIGURE A-14
).
This helps to align the connectors of Board D with the sockets of Board C,
preventing any sideways movement of the stack when you press home the
connectors of Board D.
11. Now press home fully the connectors of Board D.
You might find it helpful to seat the middle connector properly before the other two
connectors.
12. Tighten the screws into the metal hex standoffs so that the stack sits firmly on the
motherboard.
Tighten each screw a little at a time to avoid bending and possibly damaging any of
the boards. (The recommended tightening torque is 0.3 Nm.)
13. Replace the processor cover which you removed in Step 2.
Make sure that you put the tabs on the processor cover back into their original
position underneath the rear I/O card.
