bbeepp Posted January 9, 2013 Share Posted January 9, 2013 Hi, Here is my story how I got my system to work My config: • CPU – i7 2700k CPU • Motherboard – Asus P8Z68-V/Gen3 • GPU – Radeon 6850 XFX (model HD-685X-ZNFC) • 32 GB RAM • OSX 10.7.5 BIOS I use patched bios from: http://biosrepo.word...s.com/asus/z68/ These are my bios settings, the rest is default or auto. - http://dl.dropbox.co...1/osx/bios1.jpg - http://dl.dropbox.co...1/osx/bios2.jpg - http://dl.dropbox.co...1/osx/bios3.jpg For my i7 2700k CPU I have set all x-Core Ratio Limit to 39. Set it higher if you want to overclock BOOTLOADER I use latest chameleon – anything above r1820 should be fine. EXTRA In extra folder I have: • patched DSDT.aml file with proper audio section, • SSDT.aml file with speedsteps - http://dl.dropbox.co...1.speed3900.zip • SSDT-1.aml file with sata section (extracted from bios), • in org.chameleon.Boot.plist I have set DropSSDT to Yes, GraphicsEnabler to YES, AtiConfig to Gibba, and UseKernelCache to YES, • and smbios.plist with macmini 5.3 definition. Speedstep works. Tested with MSRDumper and IOReg: http://dl.dropbox.co...sx/ioregCPU.png 7,63 pts in Cinebench 11 and geekbench 14500 pts. FakeSMC I use this version of fakeSMC with plugins: http://db.tt/E6yoA1Ij and hardware monitor to check temps, clocks, voltages and fans. http://dl.dropbox.co...x/HWMonitor.zip AUDIO ALC892 kext from toleda with proper DSDT patch: Name (_ADR, 0x001B0000) Method (_PRW, 0, NotSerialized) { Return (Package (0x02) { 0x0D, 0x05 }) } Method (_DSM, 4, NotSerialized) { Store (Package (0x0C) { "subsystem-id", Buffer (0x04) { 0x36, 0x84, 0x00, 0x00 }, "subsystem-vendor-id", Buffer (0x04) { 0x43, 0x10, 0x10, 0x10 }, "layout-id", Buffer (0x04) { 0x7C, 0x03, 0x00, 0x00 }, "codec-id", Buffer (0x04) { 0x92, 0x08, 0xEC, 0x10 }, "device-type", Buffer (0x11) { "ALC892" }, "PinConfigurations", Buffer (Zero) {} }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } Latest Mountain Lion is different: Method (_DSM, 4, NotSerialized) { Store (Package (0x04) { "layout-id", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "PinConfigurations", Buffer (Zero) {} }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } GFX RADEON 6850 XFX (HD-685X-ZNF) works great with GraphicsEnabler. Almost 50 FPS in Cinebench 11. Haven't tested other ports. OTHER Kexts for ethernet and esata: http://dl.dropbox.co...tAndJMicron.zip I don't use USB 3 and it does't work natively. You have to patch DSDT section and use modified kexts to make it work: http://www.osx86.net...working_...html Feel free to ask. Cheers! ps. this was also tested with latest OSX vesion 10.8.2 and worked fine! ---------- • audio edits only for ML: if you don't want to patch DSDT put this into your org.chameleon.Boot.plisl file: <key>device-properties</key> <string>7700000001000000010000006b0000000200000002010c00d041030a0000000001010600001b7fff040028000000500069006e0043006f006e00660069006700750072006100740069006f006e00730000000500000000180000006c00610079006f00750074002d006900640000000800000001000000</string> and install optimized alc892 from toleda for ML. ---------- Thanks to buoo for his great guide which was very helpful in seting up my system 1 Link to comment Share on other sites More sharing options...

pfilipp Posted May 23, 2013 Share Posted May 23, 2013 Hello, may I ask why you chose Macmini5,3? Have you tried MacBookPro8,3? I'm running similar configuration - same CPU and Mobo but with Radeon HD7850. Right now I'm running MacBookPro8,3 and Clover instead of Chameleon. I'm asking just because I'm curious. My actual config works quite fine. Link to comment Share on other sites More sharing options...
bbeepp Posted October 3, 2013 Author Share Posted October 3, 2013 I used macmini smbios because of cpu power management. Link to comment Share on other sites More sharing options...
