camley88 Posted December 25, 2010 Share Posted December 25, 2010 Had my system up and running great for a few weeks when I decided to upgrade to 4GB RAM. Now it crashed and I can't restore from a time machine restore although it goes through the whole restore. I also can't reinstall this sites image file. It crashes about 5 minutes into the install Any ideas? Link to comment Share on other sites More sharing options...

Administrators Bronxteck Posted December 26, 2010 Administrators Share Posted December 26, 2010 You should reseat the memory maybe it's not seated properly. I had a stubborn time installing 4gb of ram. Had to upgrade the bios then put one 2 gig module in let it register then add the other 2 gig's.

Mikk P. Posted December 28, 2010 Share Posted December 28, 2010 I can't start installation from an empty HD with 3GB of memory. I need to remove the 1GB stick and then re-try. It gives me a Memory-Allocation error. Try installing with 2GB and adding the extra 2GB when installed. Link to comment Share on other sites More sharing options...
camley88 Posted December 29, 2010 Author Share Posted December 29, 2010 What I found is that you cannot install OS X with more than 2GB RAM. I reinserted my old 1GB sticks, installed, then replaced with the 2GB sticks. Also, I kept getting a memory error on booting that said to reseat. I kept reinserting to no luck. What I did was disconnect the small cable next to the watch battery at the top under the keyboard. With the battery out, this resets the BIOS (I think). When I do this, the first time I reboot, it takes me to setup where I reset the clock and everything works fine. Link to comment Share on other sites More sharing options...
