    If upgrading my Mac Pro to 32 GB, will any PC2-5300F 667 MHZ DDR2 RAM work in it? (4G or 8G Sticks)

    I read and watched a video that mentioned doing 4 8 GB sticks was a bad idea...anyone have this configuration and not have any issues?

    Again, I appreciate the help!

    Regular FB-DIMMs will work fine in your Mac Pro

    the one thing to look out for is, "4Rx4" Ranking RAM will not work in a Mac Pro 1,1-2,1. make sure to only get "2Rx4" ranking RAM

    4 8GB sticks will work fine :) (Just make sure to get "2Rx4" RAM)
