i have a question about memory. i want to get the best possible memory i can, in 1 stick of 1gb form, and i can get another stick later. the best timings i found were 2-3-2-5, is that the lowest? also, can i use any speed of ram? im getting an ultra d, and even the sli-dr says it goes to ddr400. could i run faster ram on an ultra d? waht i'm looking for here is the best possible ram, that will run on an ultra d with the lowest timings for overclocking. preferably uner 150$.
