In system profiler the card reads as an 'NVIDIA Chip Model 256 MB'. My 27' and my 23' display both lid up as Lion loaded to the desktop.

Booting up the system with the new card in the machine worked like a charm. I have carried out a test of installing an Nvidia Geforce GT630 in my Mac Pro 1.1.īefore plugging the card in, I installed the Nvidia drivers for 10.7.4 Lion. « Last Edit: October 29, 2012, 06:39:59 PM by Kristian Thomsen » A question regarding this is whether the 10.7.4 Fermi drivers are suitable for the GT630 DDR3 card (Fermi chip), or the card will require 10.7.5 Kepler drivers as a result of being a 6 series card - thus making the GT630 unsuitable for a Mac Pro 1.1 with OS X Lion? Therefore, although you can force the installation of the driver software on a Mac Pro 1.1, the drivers are not going to work properly. The Kepler drivers for 10.7.5 are 64bit drivers that do not load on a 32bit kernel. What i know about this subject already, from clever minds on netkas, is that: I would like to thank everybody in advance for their time reflecting about this post. How is this relevant?: More and more, GT440 and GT430 cards are becoming unavailable due to stockouts. Or does it somehow have specs that are different from those of the GT440/GT430 - that will make it impossible or difficult to make it work with Lion 10.7.4, on my Mac Pro 1.1? Device ID / Differences regarding hardware.? The Geforce GT630 DDR3 is supposed to be a rebranded GT440 - but is it compatible due to being a Fermi card? Will a Geforce GT630 DDR3 card work with Lion 10.7.4 and the Nvidia drivers, on a Mac Pro 1.1?īased on my reading I know that several Fermi cards are supported in 10.7.4, counting the GT440 and GT430. I would like to know (what remains an unanswered question for me inspite of fairly profound reading): I have spent hours reading through the posts about GPU upgrades for Mac Pro 1.1's.įor all the information shared I thank all the authors!
