Hi, I'm new here, so please don't flame me too much, haha. The title speaks for itself, I have found an incredible deal on a used G5 quad, and I noticed that the 3870 specs don't specifically list having a Mac Pro as a req., and also that it does automatically scale down to PCI-E 1 instead of 2.0. Does this mean that it could work? I would like maybe a little more performance then what is provided by the X1900.
 
I believe it should, as long as your running Leopard 10.5.2 you should be good to go.


ive flashed a few video cards for my G5 1.8 Single CPU that were PC and and recent MacPro cards and working fine under Leopard atleast.
 
it is running leopard, i wish somebody would take the plunge and try it. Oh wait, nobody has them yet because they aren't shipping for a while. :rolleyes:

Are you saying you are running Mac Pro PCIe cards in a PM G5 PCIe model system?
 
I'll be the first to say... never. Wont work. Not unless you can convince someone at ATI to write legacy PPC firmware for it.
 
There is a small chance it could work as a secondary card though. I contacted Rob from BareFeats and hes going to try it out and report back. :D
 
No, there is no chance at all of any kind that it will work in a G5. There is no bios to run it on a PPC system and no system drivers to use it. The X1900 is the most powerful card as you will ever get in the G5 unless you fork over a grand and a half for the Quadro FX 4500.

PCI/AGP and PCI-Express are very different technologies. What worked for PCI/AGP will not work in the more modern PCI-e.
 
The G5 quad does have PCI-E, so that's why I asked. Of course I know that it won't work in an AGP slot. But the dual core G5s have PCI-E.
