  1. Geforce 460GTX Supported!

    I had an Intel DP55WB mobo, Intel Core I7-760 and Gigabyte GTX 460 1GB O.C. The random freezes, crashes made me upset for a long time. I did some experiments in last week and got a good result to share with GTX 460 users. Followings are my procedures: Prepare: 1. Set BIOS to proper settings for Snow Leopard running - AHCI, HPET,...,etc. 2. Turn off Core i5 Turbo boost, speed step, enhance speed step. Actually I overclocked my FSB to run 4 cores at 3.4GHz maximun. 3. using DSDT auto patcher under windows to get a proper dsdt for my hardware. I also verified my hardware stability under windows, too. Installation: using latest tonymacx86, [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]/[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] and Chameleon 2 rc5 trunk 700, SleepEnabler (downloaded from kexts.com) 1. Install snow leopard. 2. Update 10.6.6 combo 3. Install retail nvidia fermi card drivers and patch device id manually. 4. run [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] and just install the kexts I need but didn't use easy beast or user dsdt installation. The kexts I installed: ACPIMonitor.kext IntelThermal.kext ALC8xxHDA.kext JMicron36xATA.kext EvOreboot.kext JMicron36xSATA.kext FakeSMC.kext NullCPUPowerManagement.kext IONetworkingFamily.kext SleepEnabler.kext Intel82566MM.kext SuperIOFamily.kext 5. Set system information to "MacPro 3,1" 6. edit "/Extra/com.apple.Boot.plist" add "DSDT" 7. boot into fresh new 10.6.6 and then download a small utility "Wallsaver" from macupdate site. run Wallsaver to enable any quartz screensaver as my desktop background. 8. Start installing other softwares and my daily works. I had more than 2 days uptime without any freeze, crash. That was not happening before. I don't know why or which steps make fermi card system more stable. Maybe turn off CPU speed stepping, turbo boost features, sleepenabler or Wallsaver. But no doubt, stablity was improved quite a lot. I'm sick about fermi card problem under OSX86. I will not try to modify any settings of my current OSX86 installation. compare to my previous unstable installation, the differences are: 1. disable Core i5 CPU all speed stepping features, turbo boost from BIOS. 2. SleepEnabler. 3. New version of Chameleon, [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] 3.1 4. Set system as "MacPro 3,1", I used "MacPro 5,1" and AppleGraphicsPowerManagement.kext patch before. This time I just used MacPro 3,1 without AppleGraphicsPowerManagement.kext patch. 5. Wallsaver If you want to figure out why, please follow above procedures and start your experiments. Good luck. Update my OpenGL Extension Viewer and Cinebench scores: OpenGL Extension Viewer Old unstable installation: 3000~3200 New installation: 3500~4200 Cinebench: Old unstable installation: 21~22.x New installation: 27~29.x
