  2. ATI5970 Mountain Lion - QE/CI is not enabled

    hmm... just tried. It looks like this key AMDHemlockGraphicsAccelerator is not being read in the plist. System boots ok but without QE/CI. what framebuffer does it specify? Any instructions on patch the binary?
  3. ATI5970 Mountain Lion - QE/CI is not enabled

    and I seem to have this extra display problem: I have only one display connected but the displays shows 2. One display is ID 756E6B6E-0000-0717-0000-00005B81C5C4 and another one ID is: 00000610-0000-9236-02D9-061300000000 How do I remove the other display? (set AtiPorts=1 doesn't help)
  4. ATI5970 Mountain Lion - QE/CI is not enabled

    Thanks fantomas1, Yes, only one core is actually working. Is there anybody managed to get two cores in 5970 to work? I checked over the plist, it looks like the settings are the same with Cypress Family. It's probably won't work since it didn't disable the second GPU. I tried to add the device ID to the Cypress Family without Disable GPU, it fails to boot. But do you know if anybody manage to get two cores of 5970 to work?
  5. ATI5970 Mountain Lion - QE/CI is not enabled

    I think i just got this to work. Previously in Snow Leopard, 5970 needs to disable the second GPU by adding: <key>IOPCIClassMatch</key> <string>0x03000000&0xFFFF0000</string> in the ATIRadeonX3000.kext. But later on in Lion, this constraint is not needed anymore. But in the mountain lion, ATIRadeonX3000 is replaced with AMDRadeonAccelerator.kext, and I need to explicitly disable the GPU again as well as adding the device card in the Cypress family.
  6. ATI5970 Mountain Lion - QE/CI is not enabled

    Greetings, I am not sure if anybody tried to enable QE/CI for ATI5970 in MountainLion. The card has been working great since Snow Leopard to Lion. The only thing need is just a modification of ATIRadeon5000Controller.kext by adding the cardID and VendorID in IOPCIMatch as "0x689C1002". Mountain Lion always installs fine. I use xMove and modified the ATIRadeon5000Controller.kext in the Installer before start the install. And it boots fine into Mountain Lion. The only problem that I have is the QE/CI (QE/CI was enabled in the Lion and SnowLeopard). From my reading so far, it looks like I need to add the card ID and vendor ID to the AMDRadeonAccelerator.kext. But ATI5970 belongs to Class Name "Hemlock" which is not listed in the AMDRadeonAccelerator.kext. I tried to add it to the Cypress IOPCIMatch key, but doesn't work out for me. It stuck after [iOBluethController] Started, which i think it's related to that change. Can anyone share some light into this? It's kinda frustrated when QE/CI is not enabled (feels like screen got torn sometimes) Thanks in advance.

  8. Kernel Panic after installation

    ya, I am installing it on to SATA 2 but it can boot. So I guess that's not the problem of SATA 2 even though it took me like 3 days to get it to work. Did you overclock your Opteron? And where did you hear about the SSE3? I think Opteron 165 Support SSE3, doesn't it?
