johnak47 Posted October 10, 2011 Share Posted October 10, 2011 Hello there , i am using snow leopard 10.6 gm hazard release to boot to SL i can not get it running with both CPU cores. I ran a copy of marvins amd utiility to patch the CPUIDS right after install , when i try to boot using the cpus=2 flag, only 1 cpu core only ever shows up in system info , the cpu itself is a AMD 2.6ghz am2+ dual core . i find it too slow too work with in single core mode as i am always usually running DJ software or Music making programs and really want too try get something sorted asap the motherboard in question is a msi k9agm3 i have no bios updates and no customiation for cores in my bios . also 2 things im slightly unsure of , the FAKESMC and DMOS from the hazard install disk were left as default could perhaps changing any of these settings stop me from booting in dual core mode ??? can anyone point me in the right direction as to anything else that could perhaps help me get this fully set up =D Link to comment https://www.insanelymac.com/forum/topic/269918-amd-cpu-problem/ Share on other sites More sharing options...

TheDub Posted October 27, 2011 Share Posted October 27, 2011 Use Nawcom's ModCD or ModUSB to do a retail snow leopard installation. Then you can use the combo update to install 10.6.8 (don't reboot) then install the Legacy Kernel (also available from Nawcom) for 10.6.8 which includes 64 bit support - make sure to check the AMD force64 option or add it yourself to com.apple.boot.plist. You will then have to patch some files to enable 32bit applications to run properly in a AMD 64bit userland. So. 1.)Use Nawcom ModCD or ModUSB to install a Retail Copy of Snow Leopard (don't be a pirate!) 2.)Once installed download the OS X 10.6.8 Combo Update from Apple 3.)Install the Combo Update - DO NOT REBOOT! 4.)Install the 10.6.8 Legacy Kernel which you can get here: http://blog.nawcom.com/?p=791 5.)Read this forum post and follow the instructions carefully to patch your binaries to be AMD64 friendly: http://osx86.co/f57/amd-and-legacy-t7263/ (specifically look at Post #4 by Akimoa - that is what you have to do) 6.)Enjoy Snow Leopard!
