Hey all, I had 4x4GB of RAM in my computer totalling 16GB. I had to send back two 4GB RAM sticks (one was bad) to Corsair. I now have 2x4GB in my computer totalling 8GB of RAM. I received the package with my new RAM in it today and for some reason Corsair sent me back one 16GB stick. I'm now not sure what to do. Is it ok to use 2x4GB and 1x16GB of RAM (totalling 24GB) or will that cause performance issues? Or is it best to just bite the bullet and go buy 2x4GB of RAM so in the end I will have 4x4GB of RAM bringing me back to where I started, but unfortunately costing me money. Any help would be much appreciated. Thanks!
