When you say "attached together". what do you mean. Do you have a picture of the card? Do you mean like a GX2 type card? SLi on a mac is impossible as there are not the drivers, however I have managed to set up Sli'd cards so that OSX sees 2 separate cards. Then if you dual boot windows you will not have to keep swapping your hardware and they will work as SLi.

Hey Aqua-mac,

 

I tried to PM you but it seems your mailbox is full.

 

I noticed you mentioned you knew a way to cause Mac OS to recognize both cards as two separate cards?

 

I have two 8800GTS 640MB set up in SLI and would love to be able to switch back and forth between Mac OS and Windows without having to swap out the second card. I currently only have one of the cards in using NVinject.

 

Can you provide me any direction or point me to another thread for how I can get this figured out? I'd greatly appreciate it. Thanks!

Hi apexmusic,

 

I have made a dual GFX strings file for you that you can download here:

 

http://rapidshare.com/files/141469244/aqua...trings.zip.html

 

You will need to follow my walk through which is here:

 

http://aquamac.proboards106.com/index.cgi?...&thread=569

 

But you will not need to download the files suggested at the top as I have included modded ones for the 8800 GTS here.

 

You will need to do do 2 things to get this to work:

 

1. Find the PCIe addresses as explained in the walkthrough and edit the file here. I cannot do this for you as every motherboard is different.

 

2. You will have to make sure you delete NVInject as this overwrites the GFX strings info and there would be no change to your current situation if you leave it in.

 

Good Luck, let me know how you get on.

Mr.Aquamac, just the man I need to see. After following you (and several other similar) guides on using EFI strings to use dual video cards, I find myself lost somewhere in between "it works" and "wtf". I have gotten to the point where I can indeed see both cards listed in System Profiler, and my system is usable without any kind of panic happening. However, in order to make it this far, I had to remove several kexts (NVDANV50HAL.kext, and NVDAResman.kext) that were giving me the language screen of death (the black one, not the grey one) when the system goes graphical.

A little more about the system:

 

Gigabyte X58A-UD7 mobo

Core i7 920

6GB OCZ triple channel

and what im trying to do: dual Nvidia Geforce 9800GT Silent Cell (Gigabyte brand)

I installed Snow Leopard from the Retail DVD using Kakewalk for gigabyte boards, everything worked with the exception of the sound needed one last kext. I used software update and went to 10.6.3 with no problems at all.

 

I followed the swapping procedure, and I can use either card in either slot on its own with full acceleration, QE/CI all that jazz. I can even run dual monitors on the one card just fine. In order to make it all the way to finder, I have to remove those two kexts I mentioned, but now im stuck with only 1 monitor, 1024x768 resolution, and System Preferences shows no other modes available. Unless it was part of Kakewalk, which I dont think it was, theres been no tomfoolery with NVinject, NVenabler(64), natit or any of that sort. I created .plist files with OSx86Tools for each card indiviually. I combined them using OSX86tools as well. I got the same results doing things by hand with PlistEdit Pro and gfxutil. I guess the forum wont let me upload the files, so ill paste them here at the end.

I don't care about SLI, I just want 3 monitors (maybe 4 later) For the love of god what am I doing wrong?

 

EDIT: apparently these codeboxes dont like xml much. let me know if you want the original files.
