Hey All, 2 Quick Questions 1. Being I bought my T4220 with a 2 gig (x1) stick and wish to upgrade it to 3-4 gigs but I keep hearing that vista 32x doesnt support 4 gigs of ram. So I called fujitsu and they said of course it does, and they had never heard of that before. So I just wanted to know what everyone else heard. 2. Would this type of ram be compatable with my t4220 http://www.newegg.com/Product/Product.aspx?Item=N82E16820145097 and also why are some RAM sticks so much more expensive and some so much cheaper with similar specs?
