Hi everyone,
I have spent hours reading through the posts about GPU upgrades for Mac Pro 1.1's.
For all the information shared I thank all the authors!
I would like to know (what remains an unanswered question for me inspite of fairly profound reading):
Will a Geforce GT630 DDR3 card work with Lion 10.7.4 and the Nvidia drivers, on a Mac Pro 1.1?
Based on my reading I know that several Fermi cards are supported in 10.7.4, counting the GT440 and GT430.
The Geforce GT630 DDR3 is supposed to be a rebranded GT440 - but is it compatible due to being a Fermi card?
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...?
How is this relevant?: More and more, GT440 and GT430 cards are becoming unavailable due to stockouts.
I would like to thank everybody in advance for their time reflecting about this post.
What i know about this subject already, from clever minds on Netkas and Macrumors, is that:
The Kepler drivers for 10.7.5 are 64bit drivers that do not load on a 32bit kernel. 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.
- 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?
Best regards
