Dude, you can overclock a dell but it will cost you some money.
heres how:
1. Go to your local store and buy a big steardy clock (preferably one that can handle about 30-40 lbs of weight)
2. Place your clock on the floor
3. Place your "DELL" over the clock
Dude, you got an "OVERCLOCKED" Dell.
i did a lot of research into overclocking a Dell. Theres no way you can do it. I ended up selling my system (for a profit ofcourse) and built my own. right now i have my 1.6a @ 2.4 and have plans on going higher soon.
hold on....you said you got a P4 1.9 Ghz ? Now thats a willy (willamette) P4 with lesser cache (only 256k) instead of 512k on the newer northwoods. Get rid of that willy now. As far as i know.....Willy hardly overclock. They will hardly cross 2.0 Ghz mark and you are already there.
Dude, you got a DELL with a WILLY in it :Q
hope that helps.
