GFX Strings - DUAL CARDS - How To

Hi Everybody!

I have a strange problem. I have two MSI GTX 480 card running in SLI in windows(i.e. SLI Bridge is also connecting the two cards) with 120Hz Benq Display connected through DVI-D. For using the same PC in hackintosh, I was using EFI Strings for both cards (with Graphics Enabler=No) from your site. It was perfectly fine upto 10.6.7. When I tried the same set of Strings in 10.6.8, everything goes fine up to the point where the screen finally flashes to get to the main desktop. There, my LED monitor goes blank saying no signal detected. Surprise, the same EFI Strings work perfectly fine in Lion 10.7, but then not again in dev preview 10.7.2, the same "No Signal Detected" problem. This is the case with my first card. As for SLI in windows all display comes from 1st (Master) card only. But if at that point of display going blank, if I connect my DVI-D cable to second card after detaching it from first card, then the display is there and everything is normal. In the console log there are two messages

Kernal: NVDA, Display A: Not usable
Kernal: NVDA, Display B: Not usable

though both cards show up in System Profiler along with all the infos put into the EFI.

The location paths for the Cards are

PCIROOT(0x0)/PCI(0x3,0x0)/PCI(0x0,0x0)
PCIROOT(0x0)/PCI(0x7,0x0)/PCI(0x0,0x0)

Tried all sort of combinations suggested like, rolling back AppleACPI, IOPCIFamily. Changing NVDA, Geforce to NVDA, Parent for first card, then for second then for both, but not resolved. Yes changing to NVDA, Parent does give KPs, using HDMI instead of DVI-D. Nothing works in 10.6.8 and 10.7.2 other than connecting the display to second card.

Using one card at a time is fine with all versions. I am using DSDT for my board, MSI Big Bang Xpower and it doesn't have any edits for Graphics.

May be something needs to be modified in the in.plist for the first GTX 480.

Strange, any suggestions will be highly appreciated.

Solved.... Set the first GTX 480 as NVDA,Parent and second GTX 480 as NVDA,Child

and it worked in 10.7.2. Going to check in 10.6.8, will update the results.

Well spotted, should work in 10.6.8 too.

I am having similar problems, I have installed 3 video cards (2 gtx 480's and 1 8800 gt). I can start it up and it works, and they are all recognized by system profiler, However, I don't see qe/ci being intialized, and I have the fermi drivers installed and the graphics enabler blank in plist. Also the 480 in the first slot will display the apple logo in the startup but when to show the desktop it will not display anything. However the 2'nd 480 and 8800gt can display, but the first one cannot, even though it is recognized.

My questions is that how do I get the first 480 to display (is it the parent/child solution above, and if so how do I do that)
2nd: is there a way to get my qe/ci working and/or verify its working other than just looking the system profiler.

I have included my in.plist

Thanks....

YUP!!! it works in 10.6.8 too. My nightmare of past 1-1/2 months has ended. I would have almost ended up buying an imac if i would not have solved it.

Ahhh... Saved USD 1500

Thanks everybody.

In my view you should make one card NVDA,Parent (the one you wanna use for boot display) and the other two NVDA,Child. at

Hey guys,

First of all: Thank you for this aqua!
Second of all I would like to give something back. I read in one of the pages before that some of you had problems with one of the cards showing up as "Display" instead of its name. This also happened to me.

Simply what I did to make it work is that I redid the whole process of the gfxutil -f display thing (also make sure to use sudo). I got different results from my first time, only this time it worked!

So what I would like to say is that you should rerun just in case you have the same problem as I. Also I think that the first (0x0) or (0x1) has to be the same for both cards, which it wasnt for me the first time. However I am not sure about it, maybe someone can confirm?

[3square]

hello! great to be here, appreciate your help regarding this problem.
I've read through the post and follow the instruction, like many other i couldn't get it to work. if you can please kindly give me some extra guidance. below are some info regarding my setup and hardwares.

graphic cards & pci address:
geforce 8800GT 512MB pci-e DVI-DVI
PciRoot(0x4)/Pci(0x1,0x0)/Pci(0x0,0x0)

BFG geforce 6200 256MB pci (overclock model if that matters) DVI - VGA
PciRoot(0x4)/Pci(0x1e,0x0)/Pci(0x4,0x0)

dell xps 420 running lion 10.7 everything works : able to play dvd, iTunes showing album artworks, quicktime can play movie

remove nvenabler64.kext, uncheck graphic enabler.

currently booting with only the 8800GT installed using the efi string below.

when i boot using safe mode -x. it shows both card as loaded through the efi string
also in safe mode only the 6200 card is working




when boot normally only show a white screen and stay like that forever. although it seem lion is loaded and processing, since my hd activity light seems to show activities.

i've read on insanelymac that another member succeeded following your guide. their setup is a 8800GT pcie and a 6200 128mb pci. They did mention having to install driver from nvinstaller 9f23

www.insanelymac.com/forum/index.php?showtopic=124073&hl=6200
www.insanelymac.com/forum/index.php?showtopic=125377&hl=6200

-----worst case scenarios-------
ithough some reading i figure i can use a pci-e 16x card in the x8 slot....sooo that open up a wider range of cards.
i went through the HCL list via the osx86 wiki, i see some potential card but there are conflicting entry; one would say it work and one would say it won't. also i'm not sure if my card combo would work together

any recommendation for a nvidia pci-e 16x card that will work with my 8800 GT card, price range below $100 would be great. thank you everyone.

thanks so much! hoping that you guys can help.

[waggie]

this is the last hurdle in my snow leopard hackintosh: dual video cards.

I've followed the instructions on the first page, but the two video cards refuse to work together. I have two EVGA GeForce 210 512MB cards. They're not the flashiest cards, but they're fanless.

both video cards work independently and show 512MB in the hardware profiler. After following Aquamac's instructions, and selected the second pci-e slot as the init display (8x)... the monitors hooked up to the card in the first slot gets no signal, only the monitors hooked up to the second video card worked. meanwhile, in hardware profiler, the card on slot one shows "VRAM 1MB"

there's no "graphics enabler = yes" in any of the .plists

what am i missing?

thanks in advance for your help.


here's the .plist before i hex'ed it:

[robertdes69]

sorry for the sum question but i am a noob at this once the in.plist is done where do u put it

[mrchrister]

Hey aquamac thanks for the tutorial.

I have a ATI Saphire 5770 and a NVIDIA GTX285. SInce both gfx cards work fine together in Win7 I hope I get it to work in OSX!

With Graphics Enable=Yes I can boot to OSX 10.6.8 and in System Profiler I get both cards displayed.
BUT when I start an application that uses CUDA like Premiere CS5 I get a kernel panic.

I had no success with EFI string so far (only kernel panics).
Here is my in.plist that I tried:

I suspect the ATI part to be the problem.
Can I even run ATI and NVIDIA together?

Thanks for any help

[aquamac]

Hi there, as you have found out, GFX strings only works with Nvidia cards and ATI are not supported. Graphics enabler will set both cards but I am not supprised that CUDA does not work. I think your best bet is to use 2 identical cards I am afraid.

[mrchrister]

thats what i thought... thanks for confirming this mate! much appreciated! I already have a friend who wants the nvidia card, so everything is good

Hello all

I hav been having an issue with two cards for few days now ( not that I have been running this dual card setup for Leopard and snow leopard without any issues) recently updated to Lion and it will worked correctly on 10.7.0. The I took the 10.7.2 update and only one of the two cards work now. Basically my set up is dual 9800 GTX on a EVGA x58 MB. I used the process explained by aquamac on the 1st post. I regenerated the string in lion with no luck also. One thing that I notice that is very unusual is that with a string in place and both cards plugged in its the second card that work and I can use both DVI from that card. The 1st card is shown in the system profiler but no monitors that are plugged into the card are working or shown.

any help or advice would be greatly appreciated.
thanks

in ur in.plist, make the device type of first card as NVDA,Parent and the second NVDA,Child and it should work

for three cards, what should the third <key>device_type</key>
be? have tried parent, child, child - parent,parent, child - etc = always hangs on begin pci config. have also tried the same in dsdt. 2 cards work great. have 3x gtx570. thanks
