XPS M1330 Processor Question

Question

Quick question on the XPS M1330. I have recently purchased a Dell XPS M1330. I am looking at the processor and wondering if I will have the ability to upgrade from the Socket P "T" series to the "P" series. I know the 1330 Motherboard may not recognize a FSB speed higher than 800 mhz (from what I hear), so if it works, chances are the "P" series which runs at 1066 mhz will be downclocked. I want to try to switch for the added bonus of a lower operating voltage, and 25w of used power instead of the 35w of the "T" series.

Does anyone have any information as to if this is possible. I don't have much experience with swapping different processors. I used to think that as long as they are the same socket size, you shouldn't have a problem. I'm willing to do it, as long as the only problem is it downclocking the FSB down to 800 mhz.

Let me know what you think, and I will let you know how it works if I end up trying it!

You cannot run a 1066 MHz bus Core CPU in the M1330.   Even if the CPU will boot - and it's unlikely - you'll get only 75% of the rated speed from it.

800/1066*2.0 Ghz = 1.5 GHz.

that is, IF the CPU will even boot - Intel has a history of rearranging pins on newer CPUs and requiring different voltages - my guess would be that the 1066 MHz FSB CPUs won't even power up in an M1330 - they require a new chipset and probably different voltage regulator and socket pin assignments.

So what you are saying, is if I was able to get a 1066mhz fsb processor to boot, lets say a 2.0ghz processor would act like a 1.5ghz one? or the 1066fsb would only perform as a 800 mhz one. where would the 75% performance hit happen?

Thanks for the info!

Well, it sounds like a bust!   Thank you so much for the info.  Looks like my dream of an even more efficient M1330 will have to wait.   Thanks for the answers.
