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		: 2133.000

What have I tried?

Setting governor to "performance".

[root@rok-laptop rok]# cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
performance
performance

What else should I do?

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?
