Siccome nn ho mai visto un P4 Mobile volevo sapere se ci vuole una scheda madre dedicata, appunto per P4 mobili oppure si puo' montare anche su socket 478 o ci sono adattatori?

Ke io sappia esistono solo x notebook!

Io ho un portatile ECS G732 e vorrei sapere i Pentium 4 Mobili, non i Centrini, se si possono montare sul 478, nessuno lo sa!!!!

Mi sembra usi lo stesso socket, però non vorrei sparare una cazzata:)

Si pare sia perfettamente compatibile:)

A P4 Mobile CPU

So what is so special about the P4 Mobile CPU? First of all the P4 Mobile are normal Northwoods but built to run at a lower Vcore and built to produce less heat. Therefore it can be said that they are specially-selected Northwoods. This would give rise to the chance of a wonder chip being found. Because they perform the same as a normal Northwood, but yet they have to run at a lower core voltage, it tends to reason then that the core on these Mobile Northwoods would almost definitely be selected from the middle of a Wafer to obtain the best of Silicon. Having read this far, most users not new to overclocking would have already picked up that you would be able to reach higher speeds with these selected Processors or have them at normal speed with much less Voltage. However, I do realize sometimes that numbers or rather figures speak louder than words so have a look at this link and note the Wattage and Vcore and Thermal Design Power and Thermal Specifications =).

Rather than bore you with all technical aspects of the P4 Mobile CPU, we'd concentrate more on the more general details. For those who feel more challenged and would like to know more about the Mobile CPUs you can do so at this link The gist of it is that they have a normal "optimized" Vcore of 1.2 Volts (With Battery power) and a Vcore of 1.3 Volts for performance optimized via AC power. This information would be the most useful to yourself as you definitely do not want to put too much Vcore into this CPU without knowing what it is Spec(ed) at.

When u insert a mobile CPU into a normal Motherboard, the board's BIOs should default to the use of 1.5 Volts, as per a normal Northwood. Some Boards do have voltages as low as 1.1Volts should the need arise for you to run it at stock which you should see why in a moment.


So What is different about the Mobile CPU as compared to the normal Northwood?

Since we've already stated what happens when you put one of the Mobile CPUs into a Desktop Board, you'd have by now no doubt guess that the CPU is pin compatible with the normal P4 Northwood (Socket 478). What is different however is the packaging of the CPUs

Ciao;)

ma i pentium M non erano saldati sulla mobo?

Non mi risulta.In effetti se guardiamo alcuni notebook hanno diverse versioni dello stesso modello , cambia solo cpu! La piastra madre è sempre quella. Significa che deve essere compatibile x forza.

Non me lo ricordo, ma se fai una ricerca ne trovi a centinaia di articoli a riguardo!!:)

Risolto il dilemma.

Guardate qua:

http://processorfinder.intel.com/scripts/list.asp

in pratica ho scoperto che il processore è lo stesso e viene interpretato dalle schede madri in modo diverso ed è interscambiabile con quelli di vecchia generazione adatti a socket a 478 pin.

Mi ero posto il problema poichè tempo addietro ho acquisato un p4 a 2.4 bus a 533 molto strano;

http://processorfinder.intel.com/scripts/list.asp?ProcFam=1025&PkgType=ALL&SysBusSpd=ALL&CorSpd=ALL

era una serie D1 e di default lo overcloccavo a 18*180; successivamente ho acquistato un portatile ECS G732

http://www.ecsusa.com/products/g732.html

e decisi di montarlo sopra. Poichè avevo anche un NW P4 a 1.8 C1 con BUS a 400 decisi di provare quale dei due andava meglio in oc visto che con un programmino riesco a modificare il PLL via software e portare il bus fino a 155 stabile. In questa circostanza ho avuto la sorpresa di appurare che il D1 veniva gestito dal sistema in modo diverso dal 1.8 C1 quando nn era alimentato dalla rete. In pratica la batteria con il 1.8 C1 durava meno della metà.

In sostanza sono arrivato alla conclusione che i processori mobili con bus a 533 della serie D1 indicati in questo link non sono altro che dei comuni processori per desktop e vengono gestiti come mobile o desktop a seconda che vengono montati su schede madri normali o portatili. Infatti il mio D1 quando è legato alla rete è alimentato a 1,55 v mentre a batteria va a 1.2 V; quindi è un processore mobile.

Guardate qua:

questo è il processore per desktop:

http://processorfinder.intel.com/scripts/details.asp?sSpec=SL6PC&ProcFam=483&PkgType=ALL&SysBusSpd=ALL&CorSpd=ALL


e questo è un processore mobile:

http://processorfinder.intel.com/scripts/details.asp?sSpec=SL723&ProcFam=1025&PkgType=ALL&SysBusSpd=ALL&CorSpd=ALL

cambia solo il Thermal Spec

a questo indirizzo è possibile scaricare le caratteristiche dei P4 Mobili con bus a 533 ed è evidente quello che ho detto:
