the answer is no. You can only put CPU's with 400mhz FSB. The fastest cpu that can be used is a 2.6. I recently upgraded my stock 1.6 to a 2.2. took 6 minutes to replace and it went great. it's much faster now. Though for you to get the max speed it needs to be connceted to the ac adapter, otherwise it goes into conservation mode where it drops the cpu speed.
btw, if you didn't know this, Dell's specs tell you only 1 gb (2x512) can work. But this info is old and many use 2gb (2x1gb) in theri system with no problems..check the link..
