Hi all, I recently got a mid-2007 MBP off of Craigslist (model A1226). Only has 2GB DDR2-667 RAM. FSB on C2D is rated at 800 MHz. I cannot find any clear answer online as to whether I can upgrade the RAM to DDR2-800 RAM or if I should stick with 4GB DDR2-667. Does anyone have knowledge/experience of this? Does Apple throttle the FSB like I've heard suggested in other forums? Thanks. (If this is a repost of an old topic, sorry; I could not find it in the forums).
