Can I use a 800 mhz DVI logic board

History

I have a PowerBook G4 667 mhz DVI 15 inch with a bad logic board. Can I replace it with a 800 mhz DVI 15 inch logic board? are they interchangeable? Also, what about switching display assemblies from one to the other?

Yes, you can put a 800 MHz DVI board in a 667 MHz machine, but it is recommended to also install a secondary fan as well (the 667 MHz machines do not have the secondary fan). As for the displays, DVI displays are also interchangeable. You cannot, however use earlier Titanium model displays (Mercury or Onyx machines).

Good luck!

I knew you would know. Can he also go to the 1000 MHz board? +vote

yes! but he would need a different secondary fan.

You may be in luck. There are four logic boards listed for the G4 Titanium. A 667, 800, 867 and a 1000. Ben Eiseman is the parts man around here. He should be able to tell you in the morning which ones will work. Here's the boards: http://www.ifixit.com/Mac-Parts/PowerBoo...
