[QUOTE="Toolbox88, post: 1397111, member: 249491"] [b]Possible Solution[/b] I know this thread is old, but this solution might be helpful for anyone who is running into this problem as well. I have the same model MBP and ran into the same exact problem when I was upgrading from 2GB RAM to 4GB. I tried resetting the PRAM and now both sticks are recognized. For instructions on how to reset the PRAM, please see this link: [url=http://support.apple.com/kb/ht1379]Resetting your Mac's PRAM and NVRAM[/url] I can't say it will work for everyone with this problem, but it's certainly worth a shot. When I did it, I ended up mistakenly holding down the buttons to the point where the grey screen flashed 3 or 4 times. Not sure if that mistake helped. :\ [/QUOTE]
