re-book Posted June 13, 2009 Share Posted June 13, 2009 Hi Folks Is there a way to get sleep working with more than 3 GB RAM. My install is fresh from DVD 10.5.6 (Retail) used Chameleon RC1 and dsdt-patcher. I using EFI-String for my 7600 GT and only a view patched kext (AppleAzalia, JMicron, AppleYukon2). With 2 GB RAM my ASUS P5B Premium is mostly working fine. The sleep an wakeup is working perfect. If I put more RAM in, the sleep is broken and leads to a unusable state. I guess it has something to do with feature we call "memory remapping", which puts all the resource related information above the amount of the installed RAM. Is there a way to overcome this?

re-book Posted June 15, 2009 Author Share Posted June 15, 2009 Hi What I found now is that you have to run the dsdt-patcher again, when you change from < 3GB to > 3 GB RAM. If you don't do so it will hang with "IOAPIC version 0x20 vectors 64:87". Also, i found with file-merge 11 differences in the dsdt.aml if I compare both cases. BOOT_DFE was not affected by the amount of RAM. The option of "Memory Remaping" in the BIOS of the P5B Premium has no effect for OSX. re-book Link to comment https://www.insanelymac.com/forum/topic/170563-upgrading-ram-to-3gb-sleep-broken-solved/#findComment-1178076 Share on other sites More sharing options...
re-book Posted June 15, 2009 Author Share Posted June 15, 2009 Hi finally got sleep to work. I had to change the RAM-Modules against other brand. Additionally I had to boot with BOOT-DFE CDROM without dsdt patching. I did compile a new dsdt.aml for 4 GB RAM. Now sleep is working perfect again. solved - re-book Link to comment https://www.insanelymac.com/forum/topic/170563-upgrading-ram-to-3gb-sleep-broken-solved/#findComment-1178111 Share on other sites More sharing options...
