Um... in everest, it's just the memory that you overclock. Just benchmark's... Anyways, unless you have a nice cooling system in that comp, I would highly not recommend you do that. If you truly want to, go into BIOS and just adjust the clock settings from there. If dell has locked the bios, I think you would have to flash it. I'm not too sure. But if they have it permanently locked, you're screwed. No other way. There might be some software, but I doubt it can be very effective...
