but rarely will it ever use one core. you usually end up between the slowest(rated) and fastest(turbo) speeds.
If you want it to stop throttling of the cpu speeds then disable turbo and it will run at the rated speed. You can then do a slight overclock to your stock turbo speed with ease, but may run a little hot under load if you have a stock cooler.
ps, after reading your post again I think you have the mistaken assumption that the turbo kicks in under load. But the more load you have the slower it runs.
My problem is that the CPU is "locked" at 3.9GHz all the time -- in essence it's boosted while idle. The only time any throttling happens is when 4-5 or more cores are fully loaded at which time the CPU will randomly throttle cores down to, but not lower than, 3.6GHz.
I've tried all combinations of toggling C1E, C6, C&Q, explicitly turning the Turbo Core function on and setting the speed to 4.2GHz, but nothing seems to have any effect. The only thing that does have an effect, albeit a negative one, is changing "APM Master Mode" to something other than "auto." If I change it to "enabled" then the processor sits at 3.6GHz all the time and under load boosts cores to 3.9GHz but not to 4.2GHz. If I set it to "disabled" then my processor just stays locked at 3.6GHz.
I've tried testing with Fritz Chess Benchmark, Prime95 and SuperPI Mod 1.5. I tested with the full range of 1-8 cores with each program ( using Hyper PI for a front end to SuperPI Mod for multi-core testing). Nothing had any effect.
