    Hello,


    From our assessment, two GND pins which left floating should not impact the functionality of the device. However, please bear in mind this is not guaranteed by Intel as it does not follows the recommendation.


    There are possibility for the signal performance degraded and noises may be increase as well which may have a big impact for high speed signal.


    This information also might be useful for this issue: Migration Pinout


    I hope this helps you.

Hi Aqid,

I have measured the two pins to the other grounds and they don't seem to be connected which is a bit concerning. We are testing and validating the design with the 570Z and so far it is working ok. Any idea what sort of problem/effect we could experience if that pin is left floating?.

Regards,
