With Skylake Intel introduced Speed Shift Technology(SST), it's interesting  especially for mobile devices. But unfortunately it's disabled on VN7-792G. For those who don't know what SST is, it allows processor change frequencies more quickly to allow quicker responses from low power idle state.

It would be nice if Acer enabled SST in next BIOS update.

    Duuuuude!  I learned a little something today.  (THAT doesn't happen very often, BTW!  Man Wink )  The issue you brought up is the result of a matter of timing.  When our VN7 was in design we knew that the SST feature was coming for that processor, but it turns out that the product was done and ready to go before the SST feature was actually ready on Intel's end.  Rather than hold the product up, we released it with the SST disabled.  Now as Intel has the SST feature available and we test it to verify operation in the VN7, it is likely that we will update the BIOS to enable the SST capability.  I don't have a schedule, or even a solid commitment on that yet, as there is much testing and verification to be done first.  But it looks good right now.  Thanks again for getting in touch.  Good topic!

    Thanks for the feedback, Dude.  I'm not 'in the know' about what is going on with the SST capability in that product, but will make an inquiry and see if I can find out something on this.  Thanks much!

    i believe speed shift v2 is currently only with kabylake U processors and will not come with latest 7820HK or even desktop 7700K and thats based on intel, not laptop makers so we are out of luck.
