ok so my friend is upgrading to a 2x1 GB kit since he has windows vista. I have it too and im in dire need of more RAM. he offered to give me his two old 512's but i was wondering would it be bad to run 4x512mb... like worse than 2x512 is?
plus it automaticly drops to 2T and some times drops to 333MHz
EDIT: i think if all the sticks are matched it will (thats what it says in my DFI manual) and it will normally hurt you oc by not letting you get as high as you would if you only had 2 sticks
