    Can you share the core temperatures of your CPU when they're running benchmarks in "sustained" 31X mode? I suspect your ambient and/or hsf is doing quite well to keep the cpu thermal temperature low so turbo boost 2.0 allows the cpu cores to go to 31X

    Turbo Boost 2.0 technology factors straight from Intel's website.

    Any of the following can set the upper limit of Intel Turbo Boost Technology 2.0 on a given workload:
    • Number of active cores
    • Estimated current consumption
    • Estimated power consumption
    • Processor temperature
    When the processor is operating below these limits and the user's workload demands additional performance, the processor frequency will dynamically increase until the upper limit of frequency is reached. Intel Turbo Boost Technology 2.0 has multiple algorithms operating in parallel to manage current, power, and temperature to maximize performance and energy efficiency. Note: Intel Turbo Boost Technology 2.0 allows the processor to operate at a power level that is higher than its rated upper power limit (TDP) for short durations to maximize performance.

    -------------------------------------------------------------

    My guess is the thermal temperature of the cpu core hasn't hit the critical threshold yet so turbo boost 2.0 allows your cores to go beyond the stated maximum 2.3 ghz. Also, remember your cpu utilization isn't at 100% so....if it's at 100% and the core temperature hits the max and still getting beyond 2.3 ghz, then we can take a look. I think we are guaranteed to have 2.3 Ghz when all cores are active and if the manufacturer follows the intel design spec on hsf.

    ----------------------------------

    She's a great singer too? I'm envious!

    OK. That seems to explain it - good cooling system in M4600 + December + not 100% cpu.
    Well, she is not "mine", so there is nothing to envy me... ;)

    Hi,
    really 31x is the ratio for the first 10 seconds of testing (sorry for the unsustainable affermation!). As you can see in the attached snapshot (this is my first attachment...) it remains between 28 and 29x during all the tests.
    You can see temperatures also of both CPU and GPU.
    I think your interpretation of thermal temperature is correct, considering also the fact that I'm into a room with an ambient temperature of 21° C and the E-port replicator that enhance the fan cooling, raising the M4600 from the side of the fans.

    I have this weird touchpad behaviour that when I play Minecraft or Project Zomboid. When I use the WASD keyboard keys the touchpad input won't work - only when I don't press anything on the keyboard...
    Anyone encounters the same? Any workaround or fix?

    Hi, Jutti,

    have a look in the touchpad settings. You most probably have the TouchGuard technology enabled. Disable it and you should be able to use the keyboard and the touchpad at the same time.

    I thought she's your lady, which made me a bit envious :)

    I can't see your attachment too well :( Can you provide a better resolution image? Intel CPU will shut down your system if it's too hot to protect itself. My 2004 Pentium 4 prescott inspiron shuts down by itself when the heat is too high. That's why although it still runs, I may not be able to use it everywhere, doing anything as high ambient temperature and/or tasks raise cpu temperature = computer shutdown :(

    much better. I can see your temperature did not even hit 90. I think with your data and M-Z's data, it's likely turbo 2.0 will push your core mhz higher if temperature is acceptable. If that is true, that's good news for us users as we can probably expect our cpu to do more work for us at higher frequency, rather than expect them to work at 2.3 Ghz. This, however, does increase the importance of a good hsf system even more in a high performance sandybridge laptop. Better cooling = probably better sustainable higher frequency CPU for all cores under turbo boost 2.0.

    Her name is Isabel Leonard; here you can see a sample of her singing:
    Prendero quel brunettino Persson Leonard - YouTube (sound quality is appaling; at least compared to blueray ;) )
    You are (most probably) right - in the beginning I also had something like 2,9-3,0 GHz. But once cores became hotter it slowed down to 2,6 GHz. As I now observe temperatures it looks like processor tries to keep its temperature about 3 degrees below the limit.
