I have a Dell XPS 630i with a Q9550, and I want to overclock it to atleast 3.2GHz so that I can get better frames in WoW in crowded cities and 25-30 man raids. I tried Google, but couldn't find anything. Same with the BIOS.

 

I thought it was my dual HD 4850s causing the lag at first, so I tried putting the settings as low as possible, but that only gave me an extra 5-8 fps than the 5 or 6/10 settings that I'm using atm. It goes down to 20 in Orgrimmar when it's really crowded.

Is there a program I can download that will help me with this? Maybe a BIOS update?

Dell doesn't usually pubish a whole lot about their MOBO configurations  and whether they can be changed from the BIOS or jumper  settings on the board.  Beware that overclocking will void most units warranty.  The hazardous part of overclocking is that you may exceed the CPU's specs and push it into instability but other chips on the MOBO will have their specs exceeded too and are more likely to overheat and do permanent damage.

Since overclocking can damage my CPU/mobo, is there a way I can monitor this before it happens? Also, after what frequency (from 2.833GHz) would it be considered potentially harmful to my PC? Would 3.2GHz be alright?

It's not frequencies that do the damage, it's excessive temperatures and voltages.  You can monitor these with a general purpose hardware monitor program like HWMonitor.  CPU temperatures, the lower the better generally, but I prefer to see core temps not exceed 75 degrees c.  Perhaps a bit more is tolerable for short bursts.  Those CPU's I believe throttle performance (forcibly slow to prevent damage) when core temps approach 95 c. I may be wrong.  I should think the limiting factor will probably be the Dell motherboard, which aren't really designed with overclocking in mind.

 

The link I posted above gives some actual settings to use for the Q9550.

Shouldn't the PC shut itself down to protect it from overheating when it exceeds, let's say, 80C? I'm going to try to up the frequency to 3.103GHz.

It's possible, it will depend on the particular PC - sometimes that is configurable in BIOS.  Thermal throttling is I believe controlled by the CPU itself.

 

The sensible thing to do before you start is monitor current temperatures at stock speeds.  Make sure there is not a pre-existing problem.  It's not a bad idea to clean out dust from fans, heatsink etc. if it hasn't been done recently.

This PC has shut itself down before (maybe 5 or 6 times in the year that I've had it) to protect it from overheating. Not sure what exactly was overheating, though. I got the BSOD every single time. This hasn't happened in while, though.

 

Edit: With WoW running in the background, this is what I'm getting (Max):

 

Core #0 - 53C

Core #1 - 49C

Core #2 - 48C

Core #3 - 47C

It was faulty GPU drivers, not my CPU overheating whenever my PC shut itself down.
