My current machine has 3 GB RAM, one 1GB stick and one 2 GB stick. If I buy another 2 GB stick, does it have to be the exact same brand as the 2 GB stick already installed? Or can they be different brands and still be identical (DDR2, etc)?
I'm looking at the 2 GB options on this page for a Dell 1735: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&Configurator=MemoryConfigurator&CFG=CFG001M595821|1735&DEPA=0
