Which RAM frequency?


Mar 18, 2010

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?

Thanks :)
