1. Thanks for introducing me to the i7z tool, which I didn't know about earlier. I also enabled cpu msr support in my kernel which I didn't have earlier (and i7z requires it for detailed statistics), so now I can see the turbo clocks too .
2. Second, I meant that the CPU temperatures are high when it runs at full load, for example while compiling kernel with "make -j4" or emerging some gentoo packages like gcc (without any renicing). (And even then, I have never noticed any slowdown.) For example, running a simple openssl benchmark (which runs 8 threads)
Code:
# for i in $(seq 10); do openssl speed aes-128-cbc -multi 8; done
Code:
