You can use some higher speed memory but the system will only run at the bus speed or the slowest installed memory speed. If you install 800 Mhz memory it will not run at 800 Mhz.
Keep in mind Dell's have a history of not working with all brands of memory (and there is no pattern). I have G-Skill memory in my E510 (four 1GB memory modules) and it's working OK. For 3rd party (non Dell) memory, we usually suggest Crucial Memory as it is guaranteed to work in Dell's. www.crucial.com
