I have a HP Pavilion dv6-2190us Notebook, its got 8GB DDR3 and an i7 processor with 1.60GHz (Turbo Boost up to 2.80GHz)

I'm not sure if I'm doing something wrong or missing step or what but I can't for the life of me figure out how to get the turbo boost working.

It's a real pain because 8x 1.6GHz really sucks, I'm starting to wish I had an i5 with less cores but more clock speed per core...

Is there anything I can do either enable speed step/turbo boost or maybe just keep it overclocked all the time?

Oh, I'm running Ubuntu 10.10 64-bit.

THANKS!

Edit I followed the procure here but my results don't change at all when I execute the loop.

cpu MHz     : 1600.000
cpu MHz     : 1600.000

Can you please look in /proc/cpuinfo like I wrote in askubuntu.com/questions/37618/is-turbo-boost-working/…, then edit the results into your question? –  elmicha May 19 '11 at 5:34

Try installing turbostat (from the linux-tools package) and run sudo modprobe msr ; sudo turbostat and see what that says for the processor speed.

The frequency shown in /proc/cpuinfo is often capped at the "normal" CPU speed when in fact turbo boost is working fine.

In fact, all the info in /proc/ and /sys/device/system/cpu/ is always limited to regular frequencies by design; see kernel.org/doc/Documentation/cpu-freq/boost.txt –  Class Stacker yesterday

I have got a similar problem with my laptop, I never use ondemand option so I disable it by installing rcconf (sudo apt-get install rcconf). Just open it as root, look for ondemand voice and disable it (space key for select/deselect)!

This is a bad advice. First, the OP misinterpreted what he saw. Now you intend to help him addressing a problem that he does not have, not explaining what your assumed solution actually achieves or how it is supposed to fix anything. –  Class Stacker yesterday

Despite not getting any further using any of the solutions, according to i7z turbo boost is, in fact, working.

Not sure what did it, but hey I'm not complaining!

PS - CPU Frequency monitor applet is still stuck at 1.6GHz.

I tested the i7z script and it tells me Turbo Boost is enabled. However, using grep MHz /proc/cpuinfo does not show anything beyond the standard clock frequency of 2.3 as opposed to 2.9 GHz. –  n3rd Nov 1 '11 at 18:07
    
@n3rd All the info in /proc/ and /sys/device/system/cpu/ is always limited to regular frequencies by design; see kernel.org/doc/Documentation/cpu-freq/boost.txt Also, the CPU Freq Mons rely on this information, so they will not show boosts. –  Class Stacker yesterday

Like sad David Gardner best solution it's turbostat which in additional Linux-tools it show real frequency. It works with cpu on Ivy Bridge where cat /proc/cpuinfo can't show real info. I can also recommend to use this script

cd && wget -O .laptop-mode.sh http://goo.gl/AH0tvj
chmod +x .laptop-mode.sh && ./.laptop-mode.sh

It help tune cpu and force turbo boost to work constantly. I should notice that turbo boost not gonna work with max frequency for all cores. For frequency arrange check official information specs for you cpu.

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. –  minerz029 Dec 28 '13 at 8:14
