Hey guys im going to give my old acer aspire am5630 to my little brother. Right now it comes with 2gb ram a r7 250, q6600 processor (acer eg31m motherboard), windows vista 32bit, and a 320gb hd. I want to upgrade to 4gb ram but I know that windows vista only supports 3gb ram. If I install windows 7 64but on the pc will it be able to use 4GB+ ram? (the motherboard is a acer eg31m btw).
