I have two machines with 4GB (2x2GB) of RAM in each, they are different brands but look to be the same spec. I need to upgrade to 8GB in one of the machines and it wouldn't hurt to upgrade the other. I noticed for almost the same price I can get 2 x 4GB of another brand for the price of 2 x 2GB of the two I already own. So, here are the questions:
Can I combine the two different brands i already have (2 Corsair x 2 Kingston x 2GB) into one system?
If I can combine them would it make a difference as to what system I put the unmatched pair into? (The two systems and their uses are below)
If I can't combine them what are the drawbacks, if any, of having the same brand but different size sticks? Like 2 x 2GB and 2 x 4GB sticks bringing the total to 10GB or or maybe 2 x 2GB and one 4GB to bring it to 8GB if thats better for some reason?
