I have a laptop and I would like to upgrade the memory. I currently have 3 Gb of ram in a configuration of a 1gb stick and a 2gb stick. My laptop has 4 available slots so I have two spare.
I am thinking of buying a 4 gb stick so that I have a total of 7gb. Will that be okay to have an odd amount? I know that I have to buy compatible memory to what I have in there, but will having a 1, 2 and 4 configuration affect the performance? Or should I try and sell the one and two gig sticks and have two lots of 4?
