4GB Ram + 10.5.8 = Hang on Boot?!, Any help will be greatly appreciated.
Hey guys I have a Acer Aspire 5600. Recently, I bought myself a 4gb ram kit for this laptop. The laptop does support up to 4GB of ram. So before the upgrade I had only 1.5GB of ram. Leopard would boot perfectly fine, everything worked and nothing ever gave me a panic or crash. Now once I pop in my new 4GB kit into my laptop, windows boots perfectly yet Leopard hangs on boot. If I take one of the sticks out and leave just 2GB of ram, it works fine. Is there some sort of kext I can install to make it work with 4GB? I even memtested this ram and its stable no errors whatsoever. Could anyone please help me out?
Also, I have noticed that my chipset even though i945GM is documented to support 4GB on manufacturer's sites, people have stated that there is a hardware limitation that the chipset does not support memory remapping for the 4GB. So in my bios I only see 3GB yet in like programs such as CPU-Z I can see I have 4GB just not 4GB effective just 3GB unfortunately. So I am wondering can this present a problem for Leopard? I mean Windows would perfectly. Yet, even with a 2GB stick and 1GB stick Leopard does not work. The only way Leopard worked would be in these configurations:
Single 2GB Ram Stick
512Mb stick plus 1GB Ram Stick
2GB Ram stick plus 512Mb Ram Stick
Any other config hangs the bootup of Leopard.
