i currently have 2 512 sticks of OCZ PC3200 Value (OCZ4001024WV3DC-K), the ones with the good chips on them. this is on a dfi lanparty nforce 4 ultra-d and san diego 3700+. i want 2gb of ram. should i grab 2 more 512 sticks of the same ram or do you reccomend 2 1gb sticks of ram. what's really good, pretty decent priced ram that you would reccomend if i went the 2 1gb stick route?
