Installed 6 GB RAM now machine is super slow
2.2 GHz A1226 machine: Last night I installed the 4GB SODIMM in place of a 2 GB one to upgrade to 6GB RAM which they say is allowable for my machine. I had 2x2GB for a long time and it worked well but I just installed a new drive a few months back so I wanted to max out the RAM. Immediately upon installing and the initial boot up, the machine was smoking fast feeling and life was good. The 6GB of RAM showed up as there in the About This Mac menu. I then put the machine to sleep and went to bed. The next day my old lady started complaining about the computer being too slow to use so I rebooted again and it took about 20 minutes to boot up. It's so slow now that it's useless. I powered down, took the battery out and reinstalled the old RAM but the problem persists. Any suggestions as to what to do next? I'd really like to use the 4GB + 2GB arrangement as this 4GB stick wasn't cheap. Thanks in advance.
Is this a good question?
