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 cpu MHz : 1600.000 cpu MHz : 1600.000 cpu MHz : 1600.000 cpu MHz : 1600.000 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.

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)!

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

Right click on the panel. Select Add to Panel and use the CPU Frequency applet.

EDIT: Ubuntu is set up to always use ondemand. If you set the applet it changes after every reboot. To make it persistent I use this:

gksudo gedit /etc/init.d/ondemand

change echo -n ondemand > $CPUFREQ to echo -n performance > $CPUFREQ

Reboot.

If you mean the "CPU Frequeny Scaling Monitor", I already have it but it starts at 933MHz and tops out at 1.60GHz... – Alex May 19 '11 at 3:56
The operation of the turbo boot speed is hidden from the OS. It works automatically whenever the OS sets the speed to 1.60 GHz. – psusi May 19 '11 at 14:11
Don't change from ondemand to performance. You end up wasting electricity and overheating your hardware. ondemand is what you need. – user4124 May 19 '11 at 19:09
so what is it, do I set the applet to "performance" persistently or ondemand or what? – Alex May 19 '11 at 19:34
It's your call really. If you want persistence then apply my hack. Ondemand is already set. You would really be better of controlling it from the applet. I was just adding another option. – wojox May 19 '11 at 20:30
