I bought a SSD drive to have less heat and noise. Less heat is important to me so my pc will be less noisy fan wise. Right now I have two sticks of ram that are 1.95 volts. If I go to 65 bits windows, I will need 4 gigs of ram for: 2 gigs for 64 bit windows, 1 gig for Windows XP emulation, the rest for software, paging file, and TMP TEMP directories. Would haveing 4 sticks of ram at 1.5 volts contradict my goal of having less heat?
