Well yeah I'm sure there's a link. But the thing is, is that the Athlon Mobile chips are just Desktop chips which passed more tests. Meaning they can run faster speeds using less energy, making them cooler.
That's why they are extremely nice chips for overclocking.
Ummm, bad news. If it doesn't boot it must be in the bios. Check if your MB manufacturer has a bios update that would allow use of the Athlon M.
I'll go surfing to see if I can find any more details. What is your MB make/model?
It may have to do with the cool and quiet function of the 754 M chips. Definitely look at the bios as the problem.
EDIT - cut from an AMD message board. I was right in my guess. Special Bios required. And a special heatsink too?
"IIRC not too many motherboards will recognise them without a bios flash. And by that, I mean they will not even post. So you would have to use a regular A64 to flash, then you could put in the mobile. Also, IIRC there are few heatsinks that will work with them, because of the decreased height of the cpu (no heatspreader).
Please note that the only real advantage with them is that they run on slightly less vcore, and they are clawhammers with extra cache. They, like all non-fx A64's are unlocked for the lower multipliers only.
