That will NOT accept DDR2, if you put that in the voltage difference could fry the MB.
You could however get a quality DDR memory of higher bandwidth and it will automatically clock itself to the right frequency (in most cases).
Why would you do this?
Sometimes legacy components actually fetch a premium
as they age. Weird, but where else you gonna get it?
So, DDR-2700 may actually be more expensive than a higher bandwidth RAM.http://www.killernotebooks.com/images/logos/micro_insignia.gif
