I have an Abit kn8- sli with 1gb (2x512mb) OCZ platinum pc3200 ram. I would like to go to 2gb. If I add 2 more stix of 512mb, will I take a performance hit versus 2x1gb set? I would really like to keep my old OCZ ram as it's really good stuff. I know the older n-force 2 chips didn't like using 4 dimms, but I don't know about the n-force 4 chips. Thanks for your help, Al
