ibr4him Posted August 26, 2012 Share Posted August 26, 2012 Hi, I didn't research enough and unfortunately got a Sapphire 6750. Although I managed to get it working at native resolution but I'd really appreciate if you can help also get QE/CI working. This is the hardware: Core i5 Intel DH67BL-B3 Motherboad Sapphire Raedon HD 6750 ioreg info: daves-Mac-Pro:~ dave$ ioreg | grep ATY | | | | +-o ATY,ATY,RadeonFramebuffer@0 <class AtiFbStub, id 0x100000282, registered, matched, active, busy 0 (5154 ms), retain 8> | | | | | +-o ATY_ATY,RadeonFramebuffer <class AMDFramebuffer, id 0x10000028f, registered, matched, active, busy 0 (261 ms), retain 16> | | | | +-o ATY,ATY,RadeonFramebuffer@1 <class AtiFbStub, id 0x100000283, registered, matched, active, busy 0 (0 ms), retain 8> | | | | | +-o ATY_ATY,RadeonFramebuffer <class AMDFramebuffer, id 0x10000029b, registered, matched, active, busy 0 (0 ms), retain 13> | | | | +-o ATY,ATY,RadeonFramebuffer@2 <class AtiFbStub, id 0x100000284, registered, matched, active, busy 0 (0 ms), retain 8> | | | | | +-o ATY_ATY,RadeonFramebuffer <class AMDFramebuffer, id 0x1000002a1, registered, matched, active, busy 0 (0 ms), retain 13> my current boot.plist: <key>AtiConfig</key> <string>Vervet</string> <key>DSDT</key> <string>/Extra/DSDT.aml</string> <key>EthernetBuiltIn</key> <string>Yes</string> <key>GUI</key> <string>No</string> <key>GenerateCStates</key> <string>Yes</string> <key>GeneratePStates</key> <string>Yes</string> <key>Graphics Mode</key> <string>1920x1080x32@75</string> <key>GraphicsEnabler</key> <string>Yes</string> <key>Kernel Flags</key> <string>-v npci=0x2000</string> <key>PCIRootUID</key> <string>1</string> <key>PciRoot</key> <string>1</string> <key>RestartFix</key> <string>No</string> <key>SMBIOS</key> <string>/Extra/smbios.plist</string> <key>Timeout</key> <string>10</string> Thanks a ton!
