Alright so currently I have 4gb of DDR2 800 ram in my pc (4 x 1gb)... I want to work my way up to 8 but i cant afford to buy all 8 at one time so... Im going to buy 4gb (2 x 2gb) first. So my configuration will be the 2 x 2gb and 2x 1gb. My question is... if I buy dual channel ram, will the dual channel feature be utilized? (assuming i have one 2gb card in socket 1 and the other in socket 3 while the 1gb cards are in sockets 2 and 4)
