Dell CPU upgrade question...

I bought a Dell with an Intel P8700 processor (2.53GHz, 3M L2 Cache, 1066Mhz FSB), but I got a good deal on an T9800 processor (6M Cache, 2.93 GHz, 1066 MHz FSB) so I decided to upgrade.

(Shh, don't tell Dell I swapped out the processor!)

Anyway, Device Manager still shows the P8700 as the processor, but it registers as the T9800 in the BIOS. I'm assuming the BIOS is correct, but, because it's a Dell AND running Vista, I'm concerned that somehow, for some reason, the computer is being limited to the P8700 specs.

Should I just ignore Device Manager?
 
Did you try to update the driver under device manager for your CPU?
Did you reinstall your OS when you swapped them out? That's the problem, your OS didn't change itself, it's still stuck on the P8700.
 
yes when swapping out Cpu you must reinstall your OS and sometimes update the bios.

Is that just a notebook thing? Or possibly a Vista thing? I've installed new processors on my Desktops and have never had to reinstall Windows before (they were all running XP or older, though).
 
No sometimes you dont have to update anything if the bios picks it up right away. That only happens when the version of bios you have is compatible with the chip u installed. its a 50/50 chance but when ever updating something major like the cpu its best to reinstall windows.


If windows isnt picking it up but bios is then you need to reinstall windows to have everything in sync.

It's just like installing an OS on a hard drive then putting that hard drive into another computer system and using it as the master - It installs itself 'accordingly' to the hardware, if not then it won't run as efficiently as it should and you will just end up wasting resources.

Well that definitely worked. Windows recognizes the new CPU at full speed.

The only problem now is I'm hearing some weird squeeling noises coming from inside the computer. If I'm not touching anything it's usually pretty quiet (some occasional clicking), but if anything is happening it makes the noise. For example it will squeal as I drag a window across the desktop. It's not super loud or anything, but it's definitely there. Should I be worried? :(
 
loud noises like that is a sign of faulty hard drive.

It's really not all that loud. I had to put my ear next to the keyboard to be able to pinpoint that it was definitely coming from the laptop. I doubt it's the hard drive, since this lappy isn't even 2 months old.

I'm worried that the new CPU is either faulty, or not getting the proper power it needs. I know the previous processor had a 25W max tdp rating, and a VID voltage range of 1.00V - 1.25V. The new processor has a 35W max tdp rating, and a VID voltage range of 1.050V-1.212V.

I'm not smart enough to know what those things mean exactly, just that they're different.

I do know that my laptop had the current processor listed as an option when I was building it, so it should be compatible, but I don't know if voltages or anything need to be changed in order for it to work properly. I just know the BIOS does not allow voltage changes, so I might be kinda screwed if they do need to change.

EDIT: Ah, I just did some research on laptop voltages. The "VID" before the voltage ranges seems to indicate that I shouldn't need to adjust the voltage manually for the processor to work.

Woah! I just realized most of the noise is actually come from my power supply! The power pack itself makes a clicking sort of nose any time the computer is working, a page is loading, or if I'm scrolling a window.
