On my Windows 8 laptop, whenever I'm doing video transcoding with Handbrake, it seems to limit the CPU usage to 44% and the CPU frequency to 42% or 43% of max allowed.
That probably means the CPU runs at 100% but the frequency is about 1.14GHz only.
I know the Core-i5 has a thermal controller to issue Turbo boost when there's only one processor with intense use but I didn't knew that it would reduce frequency when all the cores are being heavily used.
Is it really possible? I live on a very hot place (it's about 35°C right now) and it's very common for computers to overheat here.
BTW, when I try to open the HW-Monitor (that I installed before upgrading to Windows 8) it freezes the computer and I have to hold the shutdown button to be able to use it again. There are other options to measure temperature?
More Info: After letting the PC cools a bit, it will use 100% of CPU power (at 2.66GHz) but then it will start going to 1.14GHz and back to 2.66GHz... It will repeat with larger and larger steps until it stays on 1.14 during the rest of the process.
