Alright i have an NF7-S with 2x256 pc3500. I wanted to know if i should take a loss by selling my ram then buying 2 sticks of 512, or if i should just get a 512 stick and use the 3rd slot? I dont know how much more unstable using all 3 ram slots will make my pc. As of now im at 210 fsb with timings of 2-2-2-11 at 2.8v. Any opinions would be great. Also if you know 1024mb vs 512mb in games would even make a difference please fill me in. Thanks.
