It is possible.. you will be running Quad Channel then...but... I don`t think it can sustain the pc3200 standard.. so i believe i`ve one`s heard that it will go back to pc2700 or even pc2100 speeds if you set more than 2 modules on your motherboard.. So it is possible..but i don`t think you will gain anything in performance... But you can still try O ..and for that on-board features.. they will consume only a small percentage of your CPU .. (1 or 2 %) (sorry for Bad english)
