Which RAM frequency? Tags: Memory DDR2 RAM Motherboards Last response: February 18, 2012 6:48 PM in Memory Share chrismani February 18, 2012 6:11:06 PM I have a pretty old desktop pc and it uses DDR2 Ram. I was going to install 4GB ram since ddr2 is getting phased out around the world and I want to pc to last some more. On the motherboard its written DDR2 667 I was wondering if I can install a ram of higher frequency in that and if my motherboard will use that whole frequency? I don't want to install a higher frequency if my motherboard cannot use that frequency because I will be wasting money. It is Acer Aspire T7925 I am sorry that I don't know about rams and it would be a great help if anyone can help me out and tell me more about these frequencies. I tested a 800 something ram on it and it worked but is it using all the 800 mhz or just 667 and idling the rest?
