Mobile Tualatins are showing up on Pricewatch. These are 512k like the server version but low voltage. Being low voltage should allow them to produce less heat in stock trim, meaning that an overclocked processor will usually also require less voltage increase, and less cooling. Anyone who's tried one contact me, I'm thinking about it!

Carshman - I couldn't find any mobiles but I did see dual mobo/tualatin server chip combos retailing for ~ $600 - $900 single cpu, $1000+ for dual cpus...

thats why I posted about the PIII-M and whether it is pin compatible with the Coppermine micro PGA processors.
I've seen an 866 PIII-M, 512K.
I think there was also a 1.13, but I'm not sure...
the cool part, it appears I'll be able to plug a Tulatin in my laptop.
700Mhz to 1400Mhz in one chip swap.
btw, during my absence from the board, I've managed to overclock my laptop.
700Mhz, up to 770Mhz w/110FSB, or speedstep of 550 @ 660Mhz w/120FSB.
I get BSOD's at 840, but my temperature controlled fan doesn't come on.
Rock stable at 770 and 660(w/1.35v no less)so I'm pretty sure its my processor hitting a brick wall.

The m-PGA form factor is different, hoping someone makes a converter. YOu probably need more voltage for overclocking, you'll have to examine the m-PGA documentation to find the voltage detection scheme. The Mobile Tualatin will only work if your chipset supports 133FSB.

you lost me dude. converter?
I have a mPGA PIII 700, do you know if the PIII-M is pin compatible?
I know they are both mPGA 495pins, but are there any different pins as they have with the desktop?
my motherboard is suppose to support 133mhz, it will definately go to 120, I've had it there.

Best documentation I can find only gives one spec for mPGA. But I would like to find a mPGA to FC-PGA converter to use it on my desktop! I'd like to see how many GHz I can get out of a mobile Tualatin at, say, 1.7v!
Although the Mobile processors have lower voltage requirements, they are built on the same size process as desktop chips, and should therefor tolerate just as much current (current increasing with voltage). And I believe the desktop Tualatins are 1.5v? So they should tolerate 1.7v? So a mobile Tualatin with the same sized transistors should tolerate 1.7v also!

mind posting a url if you have one handy?
I'm trying to find out as much as I can...
gracias.

For the specification? You can search Intel as easy as I can. I looked it up last night, took me all of 5 minutes.

I found one, just wondering if you have something better.
what signal names are for voltage and bus speed?

ok, I've found both bsel pins, question.
does a value of 0 mean open circut or closed?

0 means Closed! I had a hard time believing Intel would lable them that way, but they did! Even though it is backward from bianary code and backwards from power switches, 0 means closed and 1 means open. At least that's the way they did it on the FC-PGA chart. I can't see them changing it for the mPGA chart.

hehe
my CPU is stable at 770 w/1.6 v, stable at 660 w/1.35, I'm going to see if I can use my speedstep multiplier of 5.5 with a FSB of 133...
00 is 66, 01 is 100, 11 is 133...
but on another section is says 10 is 100...
on the same Intel paper...
either way, I can probably make both circuts open, rather than closed, that's what I'm going to try...

11 is also 133 on the FC-PGA and means open/open.
