PIN MOD not applicable to Intel M cpus/mobos?

ironic · 06-13-2006, 10:09 AM

Hey guys.

Im looking to start an Intel Pentium Mobile powered system. I am also looking for the corresponding mobo but, i looked for the PIN MOD page, and it only states for AMD cpu supported mobos.

is there an intel pin mod or Intel cpus and mobos do not need pin mod to combine together?

The pin mod is for AthlonXPs to lock in voltage, clock and multiplier speeds when the motherboard can't auto-detect.

There is no equivilant I've seen for Intel CPUs.

Ok.

Would that mean that i can't use a Pentium 4 Mobile cpu on a P4 Asus desktop mobo?

Do you have a Pentium 4 Mobile or Pentium M, they are different, you can not use a Pentium M on most desktop motherboards, but there is a socket adapter that will let you.

As far as Pentium 4 mobile....I would assume you could use that in your desktop motherboard.

Easy way to find out is to email Asus and ask them if their board supports P4 Mobile processors.

On ebay it says its an

Intel Pentium 4 Mobile 1.7Ghz:

Whats the difference btw?

Does anyone know a compatible mobo???

DarquePervert · 06-13-2006, 11:05 AM

Motherboards that work with a P4M will state that specifically. A P4M CPU will not work in a standard P4 motherboard.

ironic · 06-13-2006, 11:12 AM

Where can i find these P4 M compatible motherboards.
I dont know any that support them.

Can anyone give me a model number or summin?

I dont know whats happenned to AMD Mobile cpus on Ebay!!!
There arent any more!!!!! :@

Thats why i have to power mine with a Pentium 4 M.

Any suggestions guys? DP?

Mobile AthlonXP CPUs aren't manufactured anymore, so they are harder and harder to find.

Here's a miniITX motherboard for the Pentium M (which is the correct name) in the store here: http://www.mp3car.com/store/product_...roducts_id=163

I think the confusion stems from this ebay seller incorrectly identifying the CPU. Search for Pentium M Motherboard and you'll find plenty of options.

ironic · 06-13-2006, 11:29 AM

i foresee a big budget problem.

If there arent any more xp-m's available we've only got a few options:

Pentium M cpu which require the above mentioned mobo ($300+)
or

mini-itx systems ($400+)

or

AMD Sempron M cpus which are still too expensive ($200??)

THIS SUCKS MAN!!

I have yet to look at the auction, but there was a Mobile Pentium 4 and it sucks balls, well the P4 sucks balls as well.....stupid netburst. The Pentium M has a different architecture than P4s, it's actually based on the P3. "The next generation of processors using the Pentium M microarchitecture, codenamed Yonah, has been released under the Intel Core brand, as Core Solo and Core Duo." and we know that the new Conroe, very nice proc., is based on this architecture as well.
P4 vs Dothan:
http://www.tomshardware.com/2005/05/...over_netburst/
Good article on Dothan:
http://www.mobilityguru.com/2004/05/10/intel/index.html
To make matters worse there were indeed two versions of the Mobile P4. The Mobile P4 and the Mobile P4-M, again neither one has anything to do with the Pentium M. The Mobile P4 used 70 watts of power while the Mobile P4-M used 35 watts, had SpeedStep, and no Hyper Threading.

That auction is for a Mobile P4-M as the L2 is 512KB and the lowest L2 cach for Pentium Ms was with the Banias cores which had 1MB.

"Intel's naming conventions made it difficult at the time of the processor's release to identify the processor model.There was the Pentium III mobile chip, the Mobile Pentium 4 M (or the P4-M), the Mobile Pentium 4 (or the Mobile P4), and then just the Pentium M which itself was based on the Pentium III."

Oh I almost forgot there are also two types of Pentium M sockets 478 and 479, but there is an adapter to use a Pentium M 479 in a desktop 478 motherboard. I am unsure of where the change took place as it seems to Dothans with both 478 and 479? I believe the Pentium that I refer to as Sonoma is still called Dothan and is compatible with the Sonoma chipset, but I saw people on the Pentium Ms refer to as Sonoma as well.
"Although Intel has marketed the Pentium M exclusively as a mobile product, motherboard manufacturers such as AOpen, DFI and MSI have been shipping Pentium M compatible boards designed for enthusiast, HTPC, workstation and server applications. An adapter, the CT-479, has also been developed by ASUS to allow the use of Pentium M processors in selected ASUS motherboards designed for Socket 478 Pentium 4 processors. Shuttle Inc. offers packaged Pentium M desktops, marketed for low energy consumption, and minimal cooling system noise."

"Intel left the speed of the front side bus (FSB) unchanged. The launch of Dothan models with a faster FSB of 133 MHz (533 MHz quad-pumped) are slated for launch in the second half of the year at the earliest. By then, a new platform, Sonoma, should be waiting in the wings,"\

It's weird many tech sites and even some forums make it seem like all the 533Mhz FSB Dothans were 479 pin, but I keep finding 533MHz FSB Dothans on hardware sites listed as 478 pin.

Slow down a second first what are your space requirements? If you need to fit the PC in some place tiny then yes you'll need to go with the Mini-ITX form factor. If you have adequate space I would look at Micro-ATX motherboards. Newegg has a decent Pentium M Micro-ATX mother board for $140 new and they had two open box for $100.

Next, now that you know the difference between Mobile P4s and Pentiums Ms you should also realize there are 3 different versions of the Pentium M. You can find plenty of Pentium M processors on eBay and you can find the 1st generation Ms, Banias, very cheap. The second gens, Dothan, have smaller cores which use less watts and output less heat. The Dothan’s also double the L2 cache of 2MB vs. 1MB of the Banias. The third Pentium M, Sonoma, very similar to the Dothan’s but with FSB increased from 400 MHz to 533 MHz and NX bit protection.

As you can imagine prices are lower for the earlier generations. Pentium M prices range from $20-$90 on eBay. Now if you want to use the Mobile P4-M I with your existing motherboard I sugget you email their tech support and ask if it can support it.

Oh I almost forgot there are also two types of Pentium M sockets 478 and 479, but there is an ASUS adapter to use a Pentium M 479 in an ASUS 478 desktop motherboard. The 479 pin Pentium Ms are the 3rd generation, IIRC. I am unsure of where the change took place as it seems to Dothans with both 478 and 479? I believe the Pentium M that I refer to as Sonoma is still called Dothan and is compatible with the Sonoma chipset, but I saw people on the Pentium Ms refer to it as Sonoma as well. If it were me I would stick with the 478 Pin 400Mhz FSB Dothans as they require the lowest amount of power of all the Pentium Ms, 21 watts:
"Although Intel has marketed the Pentium M exclusively as a mobile product, motherboard manufacturers such as AOpen, DFI and MSI have been shipping Pentium M compatible boards designed for enthusiast, HTPC, workstation and server applications. An adapter, the CT-479, has also been developed by ASUS to allow the use of Pentium M processors in selected ASUS motherboards designed for Socket 478 Pentium 4 processors. Shuttle Inc. offers packaged Pentium M desktops, marketed for low energy consumption, and minimal cooling system noise."

Link to Newegg for Pentium M boards, both 478 and 479:
http://www.newegg.com/Product/Produc...ubCategory=280

There are also Celeron-Ms as well. The MSI board support 478 pin Pentium Ms and the Aopen boards support 479 pin Pentium Ms. THen ther is always the ASUS adapter and some have even used it with non-ASUS boards.
