Hi there!

I'm trying to install two identic EVGA GeForce 8600 GTS (256mb) video cards on a ASUS P5W DH DELUXE mobo.

Fist, I installed the system (Leo4allv3 + JaS ComboUpdate 10.5.3) with only the first card. It worked fine, using NVinject... all resolution, QE/CI, two DVI outputs. I had to remove the Ninject to follow up this guide... I did the "merge" of two plists, generated the hex file, pasted on com.Apple.boot.plist... and OK: Systems boots and shows (on the Apple System Profiler) the two Video Cards.

BUT, here's my problem: now I can't change resolutions, the QE/CI are disabled and there isn't any image on the 2nd and 3rd (this one in the second video card) monitors. So, only the first one has images, but still in low res.

What should I do?? Any one could help??

Thanks a lot
AHSF
ps: sorry for the bad english

try first each card single in the according slot with the correct string file for this card in this slot - send me also your plist file

I'll be home tonight and then I send you the plist file...

I've done the process: first one card, copy its PCI address (like PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)), then the other card (alone in 2nd slot, something like PciRoot(0x0)/Pci(0x3c,0x0)/Pci(0x0,0x0)), copy its address, then the two cards running together.

But before doing this, I've removed all the kexts (NVinject, NVDANV, NVDANV50HAL, etc..) related to GeForce. Is that a problem? I know I can't use both NVinject and GFX strings together...

There's no Kernel Panic, the system boots fine, but no resolution and no signal in the other monitors.

Thanks a lot, man

there is no need to deinstall this kexts except natit or nvinject - Im pretty sure that you even need some of them to get QE/CI working.
boot with debug=0x100 to find whats really causing the kp.

Ok, I'll try with NVDAResman.kext (and the ...10HAL, 20HAL, 30HAL, etc.) and tell you if it works.

By the way, my IN.PLIST (zipped) is attached.


Thanks for your help!

IT WORKED!!!!

I used the GFX strings you provided above to generate a new HEX file and paste it on com.apple.boot.plist, and also installed back the NVDAResman kexts.... and voila!!!

All resolutions, QE/CI working, three monitors!

Thank you very much, peach-os.

Hello,

I have been trying to run a 8800Gt and a 7300GS, I have done
all the strings, but the problem is that an a BADAXE2, and the
start the OS X the system freezes, not the KP and neither error
simply stop loading the KEXTS.

What would you tell me what might be happening?, Already looked in
BIOS and there is no option to do the BOOT by PEG1 or PEG2.

Thank you for your help

BTW: peach-os, when you come to Brazil can be sure that take many caipirinhas ... ;)

try also first to make each card working with strings in its specified slot. that way you are safe to use the correct strings.
on my asus board teher wasnt also an option like PEG 2 - but it worked.

send me also your plist to check it.

dont worry about the quantity of caipirinhas over here - I had enough of them.......but you know Im talking about the one and only very special caipirinha on the beach when having my first trip to brazil someday :)

Does Logic still perform good? If so this could be cool and open up lots good things, I bought a silent pretty cheap 7300gs 512 mb from Honkong might order one more. Good work man

you have to do it like everybody: trial and error.
if the cards work single withs strings - it will

with two cards the graphics seems even to be faster than before - and yes logic performs still good :D

Thanks man guess Ill have to shop in Honkong one more time then.

http://cgi.ebay.com/...em=290245141341

Got it in a week which is pretty good since Honkong is not so close to Scandinavia. Maby you can find them even cheaper but I took a chance with this card and it works good, only DVI VGA though.

I am about to build a new box, my plan is to use 3 dvi connected displays. I was thinking about 2 pci-e 7600gt. Is that a good choice or what kind of card is good to use. Is it better to use 2 similar cards or not?

from my experiences it could be even easier to use two different cards, but should work with two 7600gts

you cant merge the hex files.
you have to merge the plists and create one hexfile from it.
for example: find the plist file A that gives you the working hex file for the first card. find working plist B for the second card.
now merge plist A and B to plist C. create the hex file from C and add it to com.apple.boot.plist
