My laptop (Compaq x1000 series) has several banks to add up to 4GB of RAM. Right now I have 256 and want to increase that to either 768 or a 1 GB. The question is... What configuration will work? Does all the RAM have to be in the same size, or can I "mix" sizes (i.e. 1 stick 256, 2 sticks 512, etc)???
