Hmm... No wonder the lower spec i7 CPU's are going to have problems overclocking...
"Overclocking is very different on the Core i7. Unlike the Core 2 or Pentium D processors, the Core i7 CPU can monitor the current it draws as well as its power consumption—if it exceeds a certain level, the processor automatically reduces its clock speed. Intel calls this feature "Overspeed Protection." The limits hard-wired into the core are 100 A and 130 watts. Only the Extreme Edition allows the user to increase these values as they like, effectively circumventing the protection mechanism altogether.
Thermal power loss rises especially quickly when the core voltage is increased. Thus, it is entirely possible that a lower model Core i7 may offer excellent overclocking potential, but it will be constrained by the Overspeed Protection feature when its power dissipation triggers it. Obviously, Intel wants to prevent customers from buying an inexpensive processor and then overclocking it to very high or even extreme levels. Apparently, Intel has realized that the good overclocking potential of its processors has led ambitious users to choose less expensive models, relegating the faster (and more expensive) CPUs to the sidelines."

So, this means, basically that no longer could someone do what they have done with the Q6600 and overvolt it like crazy.
Then again, to get my processor to 3200mhz from 2400mhz, it was as simple as raising the FSB, but even this in the new processor is changed to something else.
What are your thoughts on their direction with this?
I understand why, in the companies eyes, but for us? Where overclocking hasn't exactly been welcomed, but it has become a bi-product of buying computer parts that has just been accepted?
It looks like some may use less wattage at full load, and this is where people will find overclocking head room from now on... strange.
