cheo Posted August 17, 2013 Share Posted August 17, 2013 Hi, any help would be appreciated!!!! SPECS Custom rig using Mac Pro 3,1 SMBIOS ML 10.8.2 CPU: AMD phenom II x 4 955 (black edition runnng stock 3.2 Ghz) using Sinetek 10.8 patched kernel Graphics: Powercolor ATI HD5670 (DDR3 1gb) (http://www.powercolor.com/global/products_features.asp?id=308) Ram: 8GB Ram: 2 x Kingston 1333MHz 4gb modules (Part Number 99U5458-005.A00LF) Mobo: ASUS M4A88TD-M/USB3 (http://www.asus.com/Motherboards/M4A88TDM_EVOUSB3/) STORAGE : DVD DRIVE HL-DT-ST DVD-RAM GH10L DVD-R/RW drive HDDs (ALL HDDs set on AHCI via bios) 160GB Seagate ST3160815AS (SATA II [fully functional Snow Leopard Partition, 10.6.8]) 1TB Seagate ST31000524AS (SATA III [Windows 7 x64]) 160GB Western Digital WDC WD1600AAJS-22PSA0 (SATA II [Mountain Lion]) Currently booting using boot flags: PCIrootUID=1 Cpus=4 Busratio=16 GraphicsEnabler=Yes (changing this doesn’t make a difference) I have not been able to get proper working graphics using my powercolor HD 5670 on OSX 10.8.2, after many (and I mean a lot) attempts over the past few months. By attempts I mean using different sets of kexts etc. Display is set on the right resolution and QE/CI appears to be enabled (though I’m guessing only partially=transparent menu bar) however I frequently get graphics artifacts on my screen, making osx virtually unusable. Everything other than my graphics is working e.g. sound, networking (internet) etc in ML. I also have a working snow leopard setup, with graphics fully functional at my disposal. I'm taking a huge guess here (note my sarcasm) but I believe this to be the root of my problems: My powercolor card is working fine in Windows 7 & SL 10.6.8. Display is set to 1366x768x32 in ML (using a small monitor). I have tried using a lot of different Apps and the results are the same, even when disabling hardware acceleration options (where available) and the grand finale... Any help would be greatly appreciated. thank you Link to comment Share on other sites More sharing options...

k3nny Posted August 21, 2013 Share Posted August 21, 2013 You should take care of your setup first. You have some duplicate kexts and dependency problems. If the problem still persists, then I would try creating a custom framebuffer. Link to comment Share on other sites More sharing options...
