    Thank you all for your patience. We were able to get complete clarification on the services that were installed and running. The first service in question was the Intel(R) Content Protection HECI Service.

     

    That service does the following:

     

    The Intel(R) Content Protection HECI Service is used to enable premium video playback (such as Blu-ray*) for Intel® HD Graphics.  It does not collect any user information.  Disabling the service will prevent certain types of premium video from playing on the system; however, unprotected video such as user-generated content and YouTube* videos will continue to play.

     

    The second service in question was the Intel(R) Integrated Clock Controller Service.

     

    That service does the following:

     

    “Intel(R) Integrated Clock Controller Service - Intel(R) ICCS” is a service used for accessing the integrated clock controller in the PCH to adjust the clocks to the CPU (BCLK, DPCLK, and DPNSCLK).  The graphics driver uses this service to adjust the graphics clocks (DPCLK & DPNSCLK) to perform clock bending.  Clock bending adjusts the display clock frequencies to reduce screen flicker.  Originally access to the ICC registers was only available internally to the PCH’s embedded controller (ME) so the registers were exposed to host through the HECI interface.   On Intel® 8 Series PCHs and beyond, the HW has changed allowing the graphics driver to directly access the display clock registers, and the “Intel(R) Integrated Clock Controller Service” should not be necessary with those chipsets.

    In addition the “Intel(R) Integrated Clock Controller Service” is used by the Intel eXtreme Tuning Utility (XTU) to perform overclocking. Overclocking is more complicated with its larger frequency range and dynamic configuration, so the PCH’s embedded controller and SW service are used to abstract the ICC implementation.  

    Disabling “Intel(R) Integrated Clock Controller Service - Intel(R) ICCS” on Intel 8 Series PCHs will only impact the ability to do runtime overclocking with the XTU.   With older chipsets, it will also disable the ability to do clock bending (meaning you may get additional screen flicker).

    “Intel(R) Integrated Clock Controller Service - Intel(R) ICCS” does not collect any information.

     

    We apologize for any confusion or misleading that may have been created by not having this information posted at an earlier time.

    Thank you Diego_Intel, I appreciate it.

    Since I only have one 8-series test box at the moment, no worries.
