Cross-compatability with processors

[NoodleKnight]

Hi,

I have a Sony VAIO PCV-RX 463-DS desktop; apparently there were higher models built (480, 490TV) which used a Pentium 4 ~ 1.7ghz processor. My desktop uses a P4 clocked at 1.4.
Would I be able to just take the 1.7ghz processor from a higher model and put it into my RX463DS?

Thanks,
-Noodle

why would you want to? unless it was broken wouldn't it be better to just use the pc you are taking the cpu from. in addition it would be cheaper to just purchase the cpu rather than source it from a pc unless you happen to have a dead one of those models lying around

faster processor; I'm just curious and I couldn't find any clear explanation online. Plus, these are old computers, it isn't hard to find an old one at a local electronics flea market/swap meet.

ok good enough reason. but if i were you i would try and get the cpu seperately.

Buy one on Newegg, it'll work.

A few potential issues.

-You need to find out the socket of the CPU's and match them
-A more powerful CPU creates more heat

Find out what model motherboard you have and post it, we should be able to find out what Socket your cpu is and find you a compatible on on Newegg
A more powerful cpu creates more heat, true, but will also come with a better fan to compensate.

Oh, sorry I thought this was a laptop we were talking about...

This is a prebuilt computer; I'm pretty sure its a socket 478/400mhz bus speed/northwood core. The motherboard, i'm not sure, I'm guessing sony built it in house because there's no company name/brand name stamped on the board.
Some online sources say that the processor is upgradable, some say it isn't. I have a good feeling it is upgradable, since it looks like other models in its class used the same motherboard.
As for heat, I'm not too worried, pre-built computers usually have a good airflow/cooling setup -- or at least mine does.

This is what a Newegg search yielded for Socket 478 P4 Chips:

These look like they'd work, but I could be wrong.
And here's a similar refurbished one:

OEM Processors won't come with any sort of a fan, you'll need to buy an additional one if you get one. Otherwise, retail processors do come with a fan.
