        Don't you mean from 5fps to 5.7fps? A whole 14% increase!

            Two days ago I bought an i7-3770 (3.4GHz, 3.9GHz Turbo). In Linux only works at the base frequency under stress (3.4GHz). Does this problem has to do with what is here discussed?
            I hate to see that Windows has more support for intel. Still I can not find how to use Quick Sync in Linux:

              Would my Intel® Core™ i5-2430M be supported? I think it supports turbo up to 2.8Ghz from its normal 2.4Ghz max.

                You might try http://code.google.com/p/i7z/ to monitor your CPU under load.
                While other methods are sometimes misleading, it shows (at least for me) that turbo is indeed working...

                  Thank you very much!!!
                  I was using cpufreq-info and some widgets for monitoring.
                  i7z seems properly monitor my i7. It indicates that the turbo is enabled and my i7 is running to 3.7GHz under stress.

                    Is this with the new drivers reported here? Or an older driver? What driver version are we talking?

                      I am not install any patch or extra driver. I use the Kernel 3.8. Apparently, my problem was only related to improper monitoring. I do not know if i7z can monitor your i5.
                      Now I think to see if your processor is using turbo, you can do the following:
                      Disable Turbo Mode from the BIOS. Compress a folder with a lot of different files (better in 7z), and control the time it takes to complete the task.
                      Then enable the Turbo Mode. Compress the same folder and check the time.
                      Compare the times.

                        Despite the name, i7z works (meanwhile) also with i5 and i3 CPUs.
                        Give it a try dh04000...

                          It works on Ubuntu 12.04 64bit with Xswat PPA.

                          So, why is this update to the drivers needed?

                            The article is about overclocking the integrated GPU, not the CPU cores (which should work for the most out of the box)...
                            ... as both is called Turbo it got mixed up in the discussion, I guess.

                              OH! I see. So now the gpu will be overclocked as well, so game performance can benefit from i3-i7's Turbo ability as well?

                              Cool. Sounds good to me.
