my computer currently has 512mb of 3200 pc400/ ddr ram. So I bought 512mb more of the same kind, but a different brand. As soon as I instlled the ram, it just made my computer keep crashing and re-starting over and over. SO i had to remove the ram, and now my computer is running fine. Is it possible that since it is a different brand its is conflicting wiht the original brand, or is more likely that my computer has a memory maximum?
