I have a Mid 2010 21.5" 3.2 GhZ Core i3 with 4GB of RAM. I just purchased 2x4GB to add, and left in the old RAM when I did this. This is ok, I assume? Also, the computer does not seem to be much faster when launching apps, etc., which I assumed it would be. The Mac is correctly displaying 12 GB RAM, I reset the PRAM, NVRAM and SMC. Is there anything I seem to be missing that would not make a noticeable bump in boot time, app launch time, etc.?
Thanks
