how is turbo boost supposed to work on an i7m? i know for the 2500k i have it can go to 3.7ghz on one core, but i have it overclocked to 4.4 on all cores.

with power state min/max at 100% i never hit the rated 2.9ghz speed. its always at 2.5ghz maximum. i stress test to make sure and it never went over 2.5ghz. tried 1 thread too.

It's pretty much the same as the desktop counterparts. If you reach 100% load, the CPU automatically activates turbo-boost.

As for why you never reached 2.9ghz, it's cause that's only when a single core is being used at 100%. If you're using all cores at 100%, it only reaches a max of 2.6ghz.

Also, you can do core parking to lower temperatures. I haven't noticed any FPS differences, other than FPS spikes in DA:O, but it happens regardless. Also, you won't have to deal with CPU throttling.

Turbo boost is part of the overheating problem, but the laptop I did my fix on is AMD.

I just got my dv7 to 94C today testing crysis 2, but then it was on a bed.... not the perfect circumstance, and it is 30c+ ambient here.
Though mine idles at 50C with dedicated on, and about 40C without. So its still pretty damn hot :/

Only click it if you can read Japanese, or willing to deal with Google translate. Only guide I can find, but it's not that difficult, you should be able to do it since it's mostly adding "_" in front of a few registries. As for whether it's worth it or not, well it lowered my temps from 80C? to 74C in DA:O. So if you don't need the extra cores, it's nice to get some extra battery life and lower temps.

Can a script be made to enable and disable the core parking through registry?

All the registry editing does is enable hidden CPU management options in the power options feature. So if you want to switch between say, 8 threads and 4 threads, you can just make custom power plans to easily switch between them. I can make a simple picture guide if you want.
