I am new to this forum and new-ish to computers. Anyways, I was thinking about overclocking my Toshiba satellite laptop with a quad core 1.4Ghz AMD a6 processor, but then realized that I had turboboost(and that overclocking a laptop was impractical). Turboboost was apparently supposed to boost my 1.4Ghz to 2.4(under load).
I installed CoreTemp and ORTHOS to check on my specs. On no load, all of my cores ran at aroung 1.6Ghz. How can this be? Under some load from ORTHOS, a couple ran at 2.7GHz and usually 1 or 2 ran at 4.5Ghz(the ones orthos put all the load on). So has turboboost made my 1.4Ghz cpu able to reach 4.5? I am really confused all help would be greatly appreciated.

first off, you will never get that 1.4 ghz CPU to 4.5 on a laptop-turbo boost or not, you will fry it. Secondly, its working right. Secondly, I would say its working right. what AMDs turbo core (turbo boost is intel, though they both work along the same lines) is attempt to improve performance by increasing the frequency of certain cores during certain applications. It does not raise the frequency of all 4 cores, in most cases it only raises the frequency of 2 cores, and only to the speed necessary to accomplish a task. So if you start an application, that turbo core thinks a higher frequency would benefit you more then four cores, then it will boost 2 of the cores up to the necessary frequency. The other cores will still be working, but at the stock frequency. If all 4 cores were initiated it would likely lead to a overheat, and if you want to overclock you should disable this feature before attempting any overclocking, not that you should overclock on a laptop.
