Sorry if I confused some with my previous post.
I did not mean "all" CPU's are the same batch, and just relabeled, but only that they might make 2 or 3 batches, and label these to 4 to 6 different speeds. We use the stampings to determine which batch CPU's came from, then know how overclockable they are from comparing the batch with others.
All 1.6GHz Pentium M's should easily hit 2.1 to 2.4 GHz.
Of course we can not in our Dell's yet, but with a DFI Pentium M motherboard, no problem.http://www.gamepc.com/labs/view_cont...d=dfipm&page=6
"The end result is that our Pentium-M 755 (2.0 GHz) was 100% stable and solid at a clock speed of 2.53 GHz "http://www.madshrimps.be/?action=get...55&articID=289
"was able to run the Pentium M at 1600Mhz and overclocked to 2000Mhz without CPU fan!!" (with fan ran P-M 1.6GHz at 2135MHz)
So will this speed really make much difference?
Check out the before and after gaming benchmarks from links above.
Well worth it.
Why not just sell them as faster CPU's?
Simple answer is customers budgets.
Many can not afford to spend more money.
Solution is to modify the jumpers so that CPU is slower, then lock it at that speed.
Both AMD and Intel have been doing this for years.
It is cheaper to manufacture the faster units, then adjust these down as market requires.
This is especially important when new naming comes out.
With P4's labeled at over 3.4GHz, the P-M 1.8GHz may look like a huge downgrade.
Will consumers want the faster labled, or the cheaper model?
They can sell both with chips from the same batch.
The 20% mentioned above was conservative, as many will overclock 40% or higher.
Check out one of the dozens of forums devoted to overclocking to see how things really are.

I have never seen a CPU that would not overclock 20% on air, but have only messed with AMD's the past few years, and this is my first Intel in a while. Others in the forums I regularly visit have had similar results with Intel's for year as well. These P-M's appear to be an overclockers dream so far.
In the early days, I though everyone ran the Pentium 75's at 100Mhz or AMD 100's at 166MHz? Guess not.. We in the overclocking community have been saving money for years (70%-300% or more saved when you overclock), by always buying a slower labeled CPU, then running it at the speed we wanted. AMD's have been in the 4000+ range for nearly a year now, but you can't buy one at that speed from the factory.
Just going from the default i9200 CPU of 1.6GHz to the 1.8GHz cost $100 extra. $300 to go to the 2GHz. Now if someone could figure out how to overclock the Dell's, we could be using the savings for extra memory, DVD burners, etc.
