Okay, so I just bought RAM for my eMac (the newest model) and everything seems to work fine. However, when I go to system profiler, I notice that the speed of the memory I got is less than the memory that came with the machine. The eMac came with 256MB of PC3200 RAM while I bought PC2700 RAM (as I was instructed to do by the salesperson). When I check online at everymac.com it confirms that the 1.42 GHz eMac takes PC2700 RAM. So why does Apple include PC3200 memory and will it hurt my system to have two different types of memory in it?
