Not to contradict what OvrClkr is telling you because I too am a Dell owner and was very disapointed in my investment because of the difficulty in upgrading and the inability to overclock the processor but not to worry my freind, I too was like you! Scouring every forum I could find, looking for usefull upgrading information on my Dell POS and I found that there is hope!( Not in the forums ironicly) Actualy, I have a licensed computer programer freind whom I lost touch with for a while and then ran across him again and was happy to find out he was a technition for Dell. Anyway, Long story short. He gave me a solution on how to upgrade my processor.
I think I can provide you with a solution because our systems are very much alike.
My OEM system was a Dell XPS 410(same board & system as a Demen. 9200)
Processor: Intel Core 2 Duo E4300 1.8Ghz Conroe (yours is better)
Socket: 775 LGA (Same as yours)
Motherboard is: Dell Inc. 0CT017
Chipset: Intel P965/G965
Southbridge: Intell 82801HH (ICH8DH)
BIOS ver. : 2.2.3 .................................................(all same as yours)
First of all, dont waste your time trying to overclock from windows with clockgen. DOESN'T WORK! clockgen doesn't recognize the right chipset.
Dell made sure of that. Fkn Dell! the Guy at starless.com is a genus and I have seen it work on many other PC's. NOT dell 0CT017!
So, to the solution...
Dell has a new bios release that was posted on 12/17/2007
Just go to Dell website / Support / Drivers & Downloads, put your service tag in and download the new BIOS ver. 2.5.3. Unzip it and double click it and it will flash your BIOS with the new version and restart your computer for you.
You now have the new BIOS!
This new BIOS will support ALL these processors.
(This is from a dell Technition right off the dell forum where a person asked for all supported Processors)

I decided to go with the MP626 Kentsfield Quad Core Q6600, 2.40G, 8MB, 1066FSB, G0
now, I shut down My computer.
Removed the case cover.
removed the fan & heat sink
removed & replaced the processor
used the thermal grease (VERY IMPORTANT)
Replaced the OEM FAN as an aftermarket fan will not fit
and rebooted the system
BIOS detected the new processor without a hitch and so did windows vista...
I was worried about the OEM fan not being enough to handel this CPU so I decided to test the heat by running it normaly.
the temps ran about 40 C Normaly wich is wonderfull
then i decided to pushit hard.
I opened about 10 IE windows wich each of them where streaming youtube videos.
I ran a compleate virus scan with my virus program
I ran a disk defragment
and decided to play need for speed undercover
(all at the same time)
the temp ran about 64 c wich was perfect because the the papperwork that came with the new processor said the maximum running temp was 71C.
SO, there you have it! a way to do everything you wanted to know.
OH, and P.S. I do recomend that you upgrade your RAM to 4Gigs if you haven't already. As this will help alot if your a moderate to heavy gamer....
