Troubleshooting Tips:

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. 

Boot Issues:

• 

Make certain you updated the fi rmware to version 4.2.8. If you did not, 

you will have to reinstall your original processor and boot into Mac OS 9 

to perform this task.

• Press the reset button marked “S1” on the logic board. This is located 

on the corner of the logic board near the PCI slots on most machines. 

You will need to reset your date & time settings as well as any AppleTalk 

settings after doing this.

• Reset the PRAM on your computer by pressing and holding the 

command - option - P and R keys at startup until the machine chimes 

3 times. You will need to reset your date & time settings as well as any 

AppleTalk settings after doing this.
