PC cpu into a laptop MB?

post #1 of 12
Thread Starter 
i have a dell inspiron 1150 and it has a p4 2.6Ghz ,and i have a p4 3Ghz ht laying around both are the same socket but the 2.6ghz is mobile and the 3ghz idk
my question is can i use the PC chip on a laptop seance they have the same socket?

EDIT: I just don't like the idea of losing out on 400 MHz of processing power.....especially if its HT I would love to hear anybody who has had good experiences with a desktop processor on a laptop.

one more question -

Is the performance of a mobile P4 processor equal to a desktop P4 processor running at the same clock speed?

No, this will not work. Yes they are the same socket, however they run at very different voltages, which is probably not going to be configurable on a laptop. There is also the issue of heat on this. The desktop processors have a much higher thermal output, meaning that desktop CPU would generate far too much heat for the cooling system on a laptop. I'm not really sure on the other questions, C2D was my first CPU so I don't know about the power of P4 desktop v. laptop.

You should be able to: http://www.cpu-world.com/Sockets/Soc...mPGA478B).html

Socket 478 (mPGA478B) is a Pin Grid Array (PGA) socket for microprocessors based on Intel NetBurst architecture. This socket was introduced in August 2001 as replacement for short-lived socket 423. The socket 478 supports desktop and mobile Pentium 4 and Celeron processors from 1.4 GHz to 3.46 GHz with effective front-side bus frequencies 400 MHz - 1066 MHz (100 MHz - 266 MHz QDR).
Laptop CPUs have different idle voltage and often have different TDPs. However, I think your two CPUs have similar TDPs. Also, your chipset has to support the CPU.

Desktop to Laptop CPU switches usualy don't work. As said, there is the voltage differnce, but also most Laptops will not support the CPU, and the BIOS is very limited as to what can be changed.

Laptop to desktop usually does work though.

wow i cant believe it, even though it cut its speed in 2 the os booted in 16 seconds (this is a clean install) while the original is about 30 seconds ,also the refresh rate is faster and such ,and i now know why it cut my speed ,the p4m is 533fsb while the desktop p4 is 800fsb so u get the point

i want to know why it was faster even though the speed was reduced

A limitation of the laptop's mobo/bios, perhaps?

that would mean that the CPU is unsupported unless it some how throttled the voltage
