I'm reading about the cosair xms dominator ddr2. I'm going to upgrade my ram and my psu. My board natively supports ddr2 800. Would it natively run the xms ram at 1000 or would I have to go into bios and change it myself. Also I'm lookin for a fanless psu if I can find a good one. Any suggestions. Just lookin for a really quiet syste, Also going to purchase the new phaxe cooler from CoolIt.
