can Pentium 4 mobile be used in normal mainboard

no i think there socket 479 which is intels mobile socket, you can however buy an socket 479 to 478 adaptor, could be wrong mind

No, socket 479 is Centrino. Before that Intel have the mobile version, which somehow use less energy than the Pentium. They are indeed 478.
 
thats why im not sure about pentium 4 M, i know pentium M and celeron M are socket 479 but im clueless in all truth about a 4 M
 
I believe that it will run, but not very fast as it will default to the lowest SpeedStep multiplier and can't be changed.
 
Most boards will run it, as said before, only at the lowest speedstep multiplier, however this gives you the opportunity to ru the FSB way higher for stock speed, i think most default to 12x. So on a 1.7GHz mobile you can run 12x142 for example, rather than 17x100, or go as high as the chip will. Another consideration is that if you can't manipulate vcore on the board it might run at standard Northwood (for e.g) voltage of 1.5V+ instead of the lower mobile voltages, theres a pin removal you can do to bring it to the lowest voltage it defaults to, this severly limits overclocking but i've found of the 13 i've had all run stock speed at lowest vcore. I've even got a 3.2 Prescott mobile to work on an MSI Neo2 board by using an older BIOS! it runs at 14x lowest so 14x200 = 2.8GHz 1.25v at boot and RMclock bumps it to 3.4GHz 1.25v in Windows by using the speedstep multiplier, prime/3D stable. Unfortunately the Northwood cored mobiles don't have enhanced speedstep.
 
Ive got a mobile celeron in a normal motherboard and had a mobile pentium in it before that. I did have some aggravation, not all boards are very happy and I renember something about bending one of the pins over, but really dont renember any details.

I bookmarked a thread on AnandTech that had a load of info on mobile celerons, most of it applys to pentiums too, it was titled Unofficial Guide to mobile Celeron overclocking success! (no linkage as unsure of rules).

TDF.

The hint and article on Anandtech that you mention was great. It removed all doubt. Unfortunately as Internet is so pervasive, there is also no guarantee about reliability of its data. I ahve come across at least one forum ( can not remember exactly ) that confidently state that using mobile version will cause damage to both CPU and mainboard.

BTW, in searching around for more information, I came to this.
http://www.sysopt.com/tutorials/article.php/12034_3608801_5. Celeron 310 can be modified to 3.2G. Has anyone ever tried or know about the other similar experiment. Does "releasing one pin " simply mean bent it.
 
I have a mobile Celeron modded to run in all 478 desktop boards without an adapter. Trouble is it defaults to 12x multiplier, meaning I get 1.2ghz instead of 1.5ghz. However, it has a thermal power of 14W at that speed and can run with a passive heatsink.
 
You mean PIV celeron? PIV mobiles don't need an adapter, just BIOS support in most cases. Can you up the FSB to match default speed? If you mean mobile Banias/Dothan Celeron i'm interested in that mod! :D

Yes. In fact, these usually do 3ghz without too much problem.
 
Yea i had one at 3.2ish when i used to mess around with them, funnily none of my Northwood PIV mobiles did much over 2.6Ghz, only had 1.6, 1.7 and 1.8 mobiles though. Most likely the extra cache holding em back.

If you can find any 533fsb mobiles, they had HT ;)

You can bend or remove it, about it causing damage, i don't see how.

You mean one pin can be removed without any harm :confused: . I want to ask if in the picture, one pin was bent to TOUCH other pin. 3.2 G is tempting result for a bit risk ah

Thats for reducing the voltage to the lowest, highlighted in white, can be bent or removed.

Oh that is even more interesting. How about the other pin. BTW, in the
http://www.sysopt.com/tutorials/article.php/12034_3608801_5, the blue pin seems to bent toward the red one. Can you tell me exactly what happen. I do not want to lose money (!!!!). BTW, unfortunately now it seems I am going to have Cel 315 instead of 310. Is there the same Economic tricks like 310 in 315.

Where are there generally information about modded pin for CPU.

Regards.
 
The bending and contacting of those pins make whatever board its put in detect it as a 200FSB cpu instead of a 133MHz one, this can come in handy in boards where you can't change the bus speed etc.. However your chip has to be capable of running a 200FSB speed
