dcook Posted February 6, 2008 Share Posted February 6, 2008 I'm looking to upgrade my old G3 B&W to run Leopard (or at least Tiger) with a 933Mhz G4 from a Quicksilver 2002. Is there anything I'd have to do to get it to work in the G3's motherboard? What about mounting that huge heatsink? Thanks. Link to comment Share on other sites More sharing options...
SticMAC™ Posted February 6, 2008 Share Posted February 6, 2008 As far as i have read you cant some of the websites say it is a buss speed issue, if it physically fits? and some refer to a power wire that must be soldered onto the processor-board from the mainboard, and so forth! It is even a problem to get an older G4 to work with any processor from the Quicksilver Machines! I'm waiting for my Dual 1.8 to arrive so I can stick it in my G4 Checkout: http://www.macmod.com/content/view/75/193/ its very rudementry Be very careful as you know the parts are not that available any more!

dcook Posted February 6, 2008 Author Share Posted February 6, 2008 Hmm, ok. What about a CPU from an older Sawtooth G4. Those are the same socket as the G3 aren't they? Link to comment Share on other sites More sharing options...
dcook Posted February 6, 2008 Author Share Posted February 6, 2008 Also, would a CPU from a quicksilver run on a logic board from a digital audio? There aren't any differences between the two that I'm aware of, but I figure I'll check anyway before I start spending all my money again . EDIT: nvm, I did some more research, and apparently the quicksilver cpu would need to be modded slightly. I think i'll just look for one that was pulled from a DA.

I think i'll just look for one that was pulled from a DA. the first gen g4 used the same socket as the g3 but it was quickly changed. the quicksilver is easily modded to function in a digital audio, all that is required is the edition of 12v to one of the screw terminals. I have a quicksilver cpu in a da board overclocked to 866 running leopard and it is pretty darn slow Link to comment Share on other sites More sharing options...
Dainas Posted February 8, 2008 Share Posted February 8, 2008 Yeah, dually at 1ghz or single 1.4ghz seems to be the lowest 'usable' speed for a G4 today in leopard. You can limp along in with a single G4 slower in that OS, I just don't know how people stand it. Also single Quicksilver G4 are supposed to be gimped in cache, and far worse than the 7447a people whine about. I do have a B&W G3 that runs Tiger pretty well with a powerlogix 1.1ghz 750GX (big L2) upgrade. I would actually recommend this over any G4 upgrade for G3 or Yikes (old socket G4) as any good program that relies on Altivec would be beyond such a machine anyways.
