Contact Information:
Installation of the processor daughtercard is the same on all
systems, simply align the 3 screw holes in the card and gen-
tly place over the logic board. Gently but fi rmly press straight
down on the two rearmost screwholes until you feel the card
“click” into place. Insert the included screwdriver and tighten
the encapsulated 3 Phillips screws into the 3 screw holes.
You’re all done - Enjoy your new processor!
Remove the protective cap from the OWC Mercury Extreme
G4 processor upgrade. The cap is located on the bottom of
the card, between the screw holes. Place the cap onto the
processor card you just removed.
Place your fi ngers gently underneath the edge of the
processor daughtercard, and with your fi ngertips, pull straight
up. Do not pull at an angle, you risk breaking the processor
socket if you don’t pull straight up.
