Cpu never goes to 2,81 Ghz after CPU upgrade
Yesterday, I have upgraded my cpu. Today I have run linpack for stress testing, however powetop and /proc/ show that processor is not fully utilized:
Package | CPU 0
Turbo Mode 0,0% | Turbo Mode 0,0%
2,81 GHz 0,0% | 2,81 GHz 0,0%
2,14 GHz 100,0% | 2,14 GHz 100,0%
1,60 GHz 0,0% | 1,60 GHz 0,0%
800 MHz 0,0% | 800 MHz 0,0%
Idle 0,0% | Idle 0,0%[rok@rok-laptop ~]$ cat /proc/cpuinfo | grep "MHz"
cpu MHz : 2133.000
cpu MHz : 2133.000What have I tried?
Setting governor to "performance".
[root@rok-laptop rok]# cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
performance
performanceWhat else should I do?

Re: Cpu never goes to 2,81 Ghz after CPU upgrade
What CPU? Consider pstates driver? Running mprime give a different result?

Upgrade from T6570 to T9600, both old Intel Penyrn. Pstate not available for such CPU.
Mprime has same results.
I'm suspecting now that TLP (I don't use laptop-mode-tools) is interfering with old configuration. What do you think?
