dynamic single core frequency change?

HEHE, 3 dedictated memory channels for each processor with enthusiast grade unbuffered DDR3. And each CPU running 8 threads
we still don't know if overclocked Yorkfield's will come out on top of stock Lynnfield yet. Remember the boost to memory bandwidth/latency will be large, and with the revamped implementation of SMT this will be an effective 8 threaded chip as opposed to 4. Turbo mode, dynamic single core frequency changes for single threaded apps, will also most likely come in to play just like it has been implemented on the new penryn based mobile platform.
I have an inspiron 1525 with a T7250 in it. I loaded up prime 95 on it the other day on just one core, then locked the affinity to core 0. I literally saw a 1/2 second jump up to an 11x multi, but could never get it to repeat. Why, do you ask? Because the stupid computer kept tricking itself into thinking that both cores were being loaded. Idontcare and I had a fairly long discussion in the AT forums about this, with the tentative conclusion being that the computer doesn't know HOW to use just one core most of the time. I understand that nehalem will be able to jump up 3x instead of 1x, but if they don't figure out a way to improve the feature then it will continue to be nearly useless.
