CPU Under-clocked???

Hello,

I just recently found the bill for dell Dimension 2400 and i was reading the the paper that came with it explaining everything that came with it. and when i was reading it it said i had 2.8 GHz CPU ...but on the computer it says i have 2.6 Ghz CPU. So, I called them and they said during the time that i bought my computer they ran out of 2.6 GHz CPUs and put in an under-clocked 2.8Ghz processor.

Is there a way to bring my CPU back up to 2.8 that it should be?

it's an Intel Celeron.

I tried in the BIOS but when i press the button or move my arrow keys nothing happens it wont go down or up..or is that not the place to do it at?

And how dangerous is it to bring the computers CPU back up 2.8 after its been 2.6 for so long?

 

You might get more help if you post this to the overclockers forum.
Generally, overclocking can damage you computer, or, invalidate Dell's warretry.

 

if you OC it back up (though technically its not overclocking since you're bringing it back to stock specs) it wont hurt the proc though it may stress the motherboard components since they make each mobo specifically for what they want to put in it. you're not going to be able to OC via the BIOS though, youve gotta use one of those OC programs
