hi guys! i would like to know if i can combine three differend rams in my motherdoard, which have two channels (A & B) with two slots each! now i have two ddr2 512mb rams each on the first slot of the two channels. I was thinking to buy one 2gb ram and one 1gb and place them in the empty slots. that would make the first channel to be populated with two rams one 512, one 2gb and the other channel one 512 one 1gb (all together 4gb ram). is it possible? if not can i use the 512 rams i allready have in the first channel and one 2gb in the other channel or is it a must the channels to have the same amount of bites to wokr properly? thanks in advance!! and sorry if i selected a wrong sub-category... 😛
