Don't worry about it Jon cuz this one will make you sound like a f****in genius. Okay here it is, I'm running 256 ram and some of my newer games run real slow especially if i add max armies to a RTS games campaign. It slows down to almost a freeze. I would like to upgrade to 512 or 1024 but i don't know exactly what it will do if it will help. So this is why i am putting the question out. What exactly will upgrading the ram do? One more question, 2nd gen said no need for ram that operates above you cpu fsb. What is the cpu fsb?
