Acer Aspire Switch 12 GPU stays at max frequency.

I have a problem (maybe it is intended?) where according to GPU-Z utility GPU stays at max frequency (800MHz) all the time, even when it seems like it should be idieling. Model with Intel Core m-5Y10C, running on win 8.1 64bit.


GPU-Z Screen

I asked about this on Intel forums, and got an advise to update HD Graphics drivers to latest version (right now i'm using preinstalled version 10.18.14.4029). Howewer, i got an error message while trying to update saying:

"Error: A customized computer manufacturer driver is installed on your computer. The Intel® Driver Update Utility is not able to update the driver. Installing a generic Intel® driver instead of the customized computer manufacturer driver can cause technical issues. Contact your computer manufacturer for the latest driver for your computer."

I want to ask if it's safe to install new drivers from Intel website, will i lose some functionality or get any problems doing so?  Or maybe there is a different way to fix GPU frequency?

    Redwend,

     

    You can remove the installed drivers and attempt to install the Intel ones, if anything, you can still install the manufacturer drivers back on again.

    I installed new intel drivers, but no changes with GPU frequency, still stays at 800MHz most of the time.

    Redwend,

     

    I do not see anything internally that addresses the processor sitting at max frequency. If you installed the Intel drivers and it still remained the same it could just be working as intended honestly, I do see that it turbos up to 2 GHz as needed.

    On my Switch 12, the Intel Extreme Tuning Utility is currently showing the graphics at 499MHz, though it's bouncing around between that and 798MHz.

     

    Maybe it's the tool?

    I got the following reply from Intel staff:

    "The Enhanced Intel® SpeedStep® Technology (EIST) of the processor should lower processor frequency to save power. You may need to check for BIOS updates or contact your computer manufacturer for additional information about this issue."

    So I just thought that it is not normal. The strange thing though is that GPU Power field shows 0.0 W when idling at 800MHz as you can see on GPU-Z screenshot from first post. Also, I tried to use HWiNFO to see if it shows different results, and they were simmilar to what Billsey said: bouncing between 798 and 499 MHz.
