The 7 Series chipsets are not formally supported by the Windows 10 versions of RST. You can sometimes get away with using specific versions that just happen to (also) support the 7 Series chipsets (though not intended to do so). I haven't been tracking this phenomenon but I know that there are folks that do so and I am hoping that they will chime in here and fill us in on their findings.
Sorry I didn't have a better answer,
