If you install your memory sticks in dual channel mode, obviously your computer speeds up.
But I have two 256mb DDR ram sticks in slot 1 and slot 2. I have one 256mb DDR ram stick in slot 3 and one 512mb ram stick in slot 4.
Would it be better to get a 512 mb ram stick to replace the DDR ram in slot 3? OR
Would it be better to just get a set of two 1 gb ram sticks to replace the memory in slot 3 and 4 ?
Or other suggestions ?
