Hi Tobias, Sorry for the confusion. To get the full 491.520 MS/s you have to use a bitstream that supports it, and it requires the 100 GbE interface to stream at that rate. It looks like you're using the default bitstream that supports 250 MS/s (called X4_200) and 10 GbE. The initial release of X410 didn't include support for the higher streaming rates but this is planned for the next UHD software release, and is currently available on master.
