Having followed Aqafadas's guide for dual graphics cards, I am able to view either card but not both.

SO far this is what I have done.

1 - created an EFI Hex script for both cards whether ini the 1st slot or second slot.

At this stage I have a hex script for both cards in my com.apple.Boot.plist that works whether there is a card in slot 1 or slot 2.

The moment I place both cards in the machine, the screen will go black after the boot screen.

Basically the machine is locking up as there are no further console messages aside from the ones you see when verbose logging.

Any guidance as to where to look is appreciated.

I am running 10.6.2 on a EP45-DS3P Mobo with 2-7600GS Video cards.

I'm also trying to do the same thing with 2 GTX 260's. I know I've had it working with a 260 and a 9500gt, but I forget how I did it.
I've tried http://aquamac.probo...a...&thread=569 and http://www.insanelym...howtopic=183349 with no success. Anyone running 2 X same GPU who's running 10.6.2 stable?

Hey DP user, after struggling for the past 2 days, I followed Kdawg's advice in that 2nd thread posted above. Go by his post on the second page! I now have both 260's running in 10.6.2!
You might have to use aquamacs thread to find the pci root for each card if you don't know them (works via windows too), then edit dsdt for each peg :)

I also have the following in my extra folder's com.apple.Boot.plist.
<key>Kernel Flags</key>
<String>GraphicsEnabler=Yes</string>

Hi Everybody,

I was Having trouble getting dual graphics to work on my MSI K9N2 Diamond in 10.6.3 as it is a NForce MCP 73 motherboard.

My Specs are
Athlon 3000+ CPU was Phenom X4 9850 had to get rid of heatin issues.
4GB DDR2 1066MHz Geil Memory
MSI K9N2 Diamond Motherboard.
Apple Airport Extreme Mini PCI-E
ASUS Xonar HDAV 1.3 Deluxe
2x Leadtek Nvidia 8600GTS 256MB(SLI) was ATI Radeon HD4870 but had to remove issues.

I tried this method http://digitaldj.net...deo-cards-more/ with no success.

Shortly After I read that Nvidia chipset Motherboards don't seem to like Multiple Graphics cards and EFI strings. but I was able to get into gui after spinning wheel with the help of evoenabler for some reason kept injecting my cards as ATI Radeon HD 4870 or 4890 depending on kext I was never able to get qe/cl and proper injection maybe some one can direct me to a unmodified evoenabler.kect for snow but then I tried nvenabler64.kext and got instant reboots. finally i gave the link above another try the pci roots seemed to be long and also every time i used the EFI string. I get Kenel Panic/Instant Reboot.

Now I knew I had a spare motherboard a Gigabyte GA-MA790FX-DS5 with my Athlon 7750 and tried to enable SLI in Windows using SLI patch 0.8 and it worked also I used the link in this post the first one.

Which worked for me and to notice the difference between my two card i use a different revision number. I have uploaded screenshot.

DP USER - if your using aquamac's dual cards guide, i assume you did the output hex on leopard? as the guide states output on snowleopard gives wrong info

also, for gigabyte boards you need set your bios to boot from PEG2 which i believe is in advanced bios features (usually towards bottom)

i had either card working 1 at a time with the combined hex/efi string, but kept getting kernel panic when i booted with both plugged in until the change to boot-PEG2 then everything worked

dont forget to remove any natit kexts or other injectors

when you have one 8400GS 512 card installed, do you get it recognized with proper driver support using EFI graphics strings?

basically as i understand it, any card you can get working WITHOUT injectors like natit, and use EFI graphics strings instead, you can get working with dual cards

you just have to get the PCI root info for each card installed 1 at time. each card installed in seperate slot will give you different hex strings, and using aquamac guide, you pretty much combine those strings as 1 long string, enabling dual cards to work

if you cant get your card to work with EFI graphics strings, you can't use the aquamac dual card guide.

i tested dual 9600 GT 512 (which show up in OSX as 8800 GT), and yes 4 screens work, all mirrored or all spanned desktop across 4 screens. pretty neat

Hello!
I have a x58a-ud3r rev. 2 with FF bios version, with Snow Leopard 10.6.8
I've been trying to install two graphic cards: a Gigabyte 8600 GT(256 mb) and a Gainward 9500 GT (1GB), and I got in the point where the I've put the 9500 GT in the 2nd PCI-X 16x slot, and the 8600 GT in the 4th PCI-X (8x) slot ( that was the easiest for me, as I have a moded G5 case, with the bios setting "PCI init dislpay set to PCI-X 8 ( 2 ), which is the slot that the 8600 Gt is mounted on .
After editing of the in.plist version, transforming it into hex and integrating it in the com.apple.boot.plist and repairing permissions, booting with -f, both of the video card appear in the Graphic/Displays, but the 9500 GTs appears as having only 1 mb and the displays are not working, because I didn't know what the corect code for that would be for the 1 GB value, so I assumed to be <00000040>, but I have tried with the <00000020>, an that didn't work, anyway.
The 8600 GT was set correctly ( <00000010> for 256 mb) and its outputs are perfectly working at highest resolution ( 2560 x 1500 ).
Do you have any idea how to solve that ?
Thank you so much in advance!
