[SOLVED] Dual 480 DSDT setup in Lion

[viztang]

Update: After fiddling with this issue for 1 week, I finally got to upgraded my DSDT and customized it for Lion. For anyone how is in the same boat, I have attached my DSDT code here for EVGA 480GTX 1.5G on my RAID setup. There is no freeze, no KP, I have enjoyed CUDA every since.

Hi guys,

I had a working 10.6.7 with dual 480GTX using DSDT mod. Everything was fine before I upgraded to 10.6.8. First thing it took me two days to revive my machine due to the APCIPlatform issue, and then the dual graphics setup and sleep just wouldn't work. I am curious if anyone could point me to a source that has shown such successful setup? Or is there any additional DSDT mod I need to put into the file?

Thanks much!

Will this work on Zotac 480? I have VRAM issues as posted here. Where do i copy/paste that code and how?

I think in general this should work with your card. The only thing I would watch out for is the PCI address for your system. I had two cards, which is on PCI bridge 3 and bridge 7 respectively. Now, you can use IORegisterExplorer to find out exactly where your card is, and replace the one in my code.

If you could give me more information, I might be able to help you create a customized version.
