I currently have 2- 256MB of DDR333/PC2700 in my system. The maximum is 2GB of 2700 or 3GB of 2100. I was wondering if I could add one 512MB of DDR266/PC2100 in the 3rd slot for a total of 1024MB Ram. My ASUS user's manual says that if more than 2 DIMMS of 2700 is installed the system will revert to a maximum speed of 266. Since I'm not adding a 3rd 2700 DIMM what will happen? Or should I just get the 2700 and let it revert back to 266Mz?
