Okay, so I have PearPC running fine, but here's my only problem, it doesn't matter what I put in main_memory in the config file, Mac OS X always reports having only 128 MB of RAM, when I have it configured to 1 GB. How do I work around this?

Also, OS X seems to be reporting different processor speeds every time PearPC boots, like last time I used it, it reported having a 1.9 Ghz processor, before that it thought it had 959 Mhz processor, and now it says its 1.8 Ghz. Why is it doing that?

I am running PearPC 0.4 on Windows 7 Home Premium on a i7 Quad Core processor.

Although I'm offtopic and not helpful, are you using a GUI or just the basic PearPC as it is? (I've never got PearPC working, I need a GUI, like VirtualBox, VMWare... )

I'm using basic.

The processor speed is probably dependent on what the rated bus speed of your processor which sometimes fluctuates depending on the activity of the computer.
Not sure about the RAM though...
