  1. 6870 with 4 monitors. Resetting display settings.

    Would gladly provide you with the temps, any suggestions on how to get them? My card has 2048 and it shows up as such, but maybe that's not what you meant? eep357: If you still have those files, I would love to try them out or did you need any more info to make them work?

    eep357: Yep, switching to scaled enables the resolution selector again. Thanks. My framebuffer line looks like this: ATY,AMD,RadeonFramebuffer@0 <class AtiFbStub, id 0x100000338, registered, matched, active, busy 0 (1965 ms), retain 8> The only problems I am having with it is the slight chopping when dragging a large window to the vertical screen (I can live with this) and when maximizing chrome, the transition effect is also choppy. Not so when doing the same with Textmate for some reason. Maybe it is just a product of having such a large amount of screen realestate? I just tried booting with Bulrushes and I got all black screens.

    The only problem so far is that I have one of the smaller monitors in portrait mode, and moving windows around on it, seems a bit choppy. Plus, I can no longer select what resolution I want for the monitors. Not that it has selected a wrong one. I suspect it is simply no longer an option in ML?
  4. 6870 with 4 monitors. Resetting display settings.

    I am speaking to you from the land 4 monitor goodness and "near-OOB" perfection. I am in a state of zen and nothing seems to bother me In other words, IT WORKS!!! For some reason, I cannot run the kakewalk installer with the ATI6000Controller.kext it provides, but when it is added back in after the installation is complete, it just works! Everything! I have been trying to see if it is running bad in some way, but I can play 720P movies and play flash games. Any other ideas to gauge if the driver is working like it should? All effects seem to be running. I cannot believe it was this simple. If only my initial ML image had not been corrupt, all this might have been avoided as I would probably have pursued that installation rather than trying to fix the old one. I did however learn something about how these cards a tied in with the system. So, to recap. Graphics card is a Club 3D Radeon HD 6870 Eyefinity 6 Edition I made a Kakewalk install stick (not sure how much this matters, it might also work with custom or myHack sticks). Then I copied the kext: /path to your Kakewalk install stick/System/Library/Extensions/ATI6000Controller.kext to an empty USB stick and removed it from the Kakewalk stick. I did not repair permissions on the Kakewalk stick, probably not important if you do or not. Then I was able to install 10.8 on the machine. I then finished installing Kakewalk to the machine and before I rebooted, I got the kext from the other usb stick and put it back in /System/Library/Extensions/ Repair permissions and reboot with boot options -v -f. It should now recognize all 4 monitors. TL;DR-version: The ATI6000Controller.kext cannot be present during OSX 10.8 installation, but must be injected afterwards to make the card work. My specs: Gigabyte X58A UD7 Club 3D Radeon HD 6870 Eyefinity 6 Edition 2GB Intel core i7 9200 12 GB 1079 MHz DDR3 Intel 80GB SSD Huge thanks to all who helped. Especially eep357 who let me waste such a large amount of his time with this enormous detour Thanks mate, I definitely ow you the infamous beer everyone seems to hand out This thread could be renamed, if you wish, to something that would help others with the same card, find this little workaround. Again, thanks for the help

    YAY! removing ATI6xxxController.kext from the usb installer did it. I now have a ML install running. Crappy graphics, but now I just need to get xcode and run ioreg to get you that file. I have a question: Do I have to add the removed kext back in before running ioreg? Because I fear that if I add it back, the system wont start up.

    Thanks I will try and then report back. And yes it has a chameleon menu, just forgot that's what it is called. So when I say "initial kakewalk screen" I am referring to the usb sticks chameleon menu.

    I have been searching for a way to do that. The installer is started by typing "exit", but that does not take any other parameters, do you know of any other way to start the installer from a booted stick?
  8. 6870 with 4 monitors. Resetting display settings.

    I would, but I dont know how. I dont have 10.8 installed. I can't get past the 2 white screens and the two flickering screens when the os installer boots up. Maybe using -x on the kakewalk installer, but I dont know if this is passed on further. I will give it a try. I could ofc also try to use duckweed to get at least 2 monitors working, I will try that too. Just a sec. Darn, none of it worked. Do you think it would make any difference if I used myHack instead to create the install stick? Wonder why that last line didn't get its own post. I can boot the kakewalk stick into singeuser mode, and it seems like any startup options I specify on the initial kakewalk screen, does not get sent along to the osx installer, but that is pure speculation on my part. Do you know of any way to type them again when performing a boot from singeuser mode perhaps?

    Hi again. Just got distracted by work. Gotta do it to try and make some of those "money" I have heard so much about. Anyway, thanks for the help so far. I have made a bios dump and I have been trying to make sense of the way it is converted into a personality, but I have given up. I have been reading something here: http://www.insanelymac.com/forum/index.php?showtopic=252061 about how to get from bios dump to personality, but I am afraid it goes a little over my head. It's actually a little embarrassing as I call my self a developer and then I can't wrap my head around this :S Could you either please help me understand? Or maybe it is just easier to do it for me? In any case, I am not sure of it makes any difference wether it is made for 10.7 or 10.8 Either way, thanks for your time so far Here is the result from the radeon_bios_decode script: ATOM BIOS Rom: SubsystemVendorID: 0x1787 SubsystemID: 0x2305 IOBaseAddress: 0x0000 Filename: B6615BHA.HH1 BIOS Bootup Message: BARTS XT 2G GDDR5 BIOS B6727BHA.HH1 PCI ID: 1002:6738 Connector at index 0 Type [@offset 44205]: DisplayPort (10) Encoder [@offset 44209]: INTERNAL_UNIPHY2 (0x21) i2cid [@offset 44341]: 0x90, OSX senseid: 0x1 Connector at index 1 Type [@offset 44215]: DisplayPort (10) Encoder [@offset 44219]: INTERNAL_UNIPHY2 (0x21) i2cid [@offset 44368]: 0x91, OSX senseid: 0x2 Connector at index 2 Type [@offset 44225]: DisplayPort (10) Encoder [@offset 44229]: INTERNAL_UNIPHY1 (0x20) i2cid [@offset 44395]: 0x92, OSX senseid: 0x3 Connector at index 3 Type [@offset 44235]: DisplayPort (10) Encoder [@offset 44239]: INTERNAL_UNIPHY1 (0x20) i2cid [@offset 44422]: 0x93, OSX senseid: 0x4 Connector at index 4 Type [@offset 44245]: DisplayPort (10) Encoder [@offset 44249]: INTERNAL_UNIPHY (0x1e) i2cid [@offset 44449]: 0x94, OSX senseid: 0x5 Connector at index 5 Type [@offset 44255]: DisplayPort (10) Encoder [@offset 44259]: INTERNAL_UNIPHY (0x1e) i2cid [@offset 44476]: 0x95, OSX senseid: 0x6

    robertx: Didn't think of that. Just tried it and it produced the same result. But thanks anyway. TH3L4UGH1NgM4N: Yep. I have just popped a new HDD in the machine and I am using that for 10.8 and no, it is not loading like 10.7. In Lion, only 2 of the screens are active. ML activates all 4 screen, but then only shows white on 2 and garbled background on the other 2.
  11. 6870 with 4 monitors. Resetting display settings.

    I have tried installing 10.8 via Kakewalk and it was not exactly a huge success. The bootloader for the installer shows up just fine, but as soon as the loading is done and the "installation desktop" is about to be shown, the monitors in the 2 first ports go all white and the monitors in port 3 and 4 comes on. They are showing the grey linen background and one time I could even see my mouse pointer, but the image flickers wildly and is broken up. The process does not seem to continue. Making it use Bulrushes, Zonalis and Duckweed and none of them work. Only Bulrushes active port 3 and 4 so I assume this is the one being used as default. The others fair slightly worse, but none of them can get rid of the whiteout on the screens connected to ports 1 and 2. I have tried switching the monitors around to see if it was my mixture of passive, active and true dp that did it, but it did not help. Not even disconnecting all the monitors except one, seemed to do anything. So it seems that 10.8 does, at least, one thing a little better. All 4 monitors are actually awake at the same time and producing light. Just not in any useful way, sadly. I still have my 10.7.2 HDD intact, so that is still an option. Just to make it clear, I have no care as to which version I end up using. Any ideas you may have please do share

    So, I googled around a bit and found a helpfull little guide to restoring kext's using singe user mode. And I am a little proud to report, that the machine is now back in the same state as before I broke it. Do you think it will help to upgrade the system to 10.8? As eep357 found, it has a slightly different Bulrushes. Maybe that does the trick?
  13. 6870 with 4 monitors. Resetting display settings.

    Yep, made a backup. And I remember the utility doing it as well. But the -x flag didn't work. Trying -x -v right now to see if it produces any meaningfull errors. Seems to have stopped as "DSMOS has arrived".
  14. 6870 with 4 monitors. Resetting display settings.

    Hi, I'm back. I used kext utility to with the file you gave, but something must have gone wrong. My chine can't boot now. It gets some kind of error, pictured below: I have let it sit there for about 20 minutes. So I am guessing something went wrong. I have read something about -s boot option will let me muck about with the files, but I thought it might be wise to seek some suggestions from here before I go and make it worse. On another note. I have an image for Mountain Lion, but I have only ever used Kakewalk and that requires a functioning mac to create the install stick.
  15. 6870 with 4 monitors. Resetting display settings.

    I am running 10.7.2 Sounds like it is worth a shot. So, do I just follow the guide in the other thread using xxd or is it just a simple text replace?
