No. You can't. They do it for a reason. They do it because if some retard super oc's they're computer then asks for a new one because it melted they will have to because it's under warenty.
this is true with just about any store bought PC. this is the laymens terms version of what AMDs' and Intels' public announcement on the issue is.
The main reason ocing isn't allowed is yes the big company doesn't want to deal with warranty issues, but tests can be run on broken, overheated CPUs to see which pins carried what voltage and it fried what part of teh architecture, but also, it allows them to make more money because you get what you pay for and if u want something nicer or better, you have to go through them.
some are a little nicer, (toshiba, Sony, and gateway) but by and large, theyre pretty mean and impossible to play with. you could check ur BIOS version, see what oc capabilities it has, then, if it has none, u could try to update the BIOS through dell, and see if it the new version has any OCing. I have heard of Dell hate sites that have tweaked versions of the BIOS but i don't know where they are and ive heard horror stories about it.
im pretty sure ur outta luck on this one.
