The answer is yes, of course, we did need the latest AMD AGESA Firmware update for the motherboard. We tested on the Crosshair VII Hero ASUS motherboard. After inserted all DIMMs, the motherboard immediately recognized the 3200 MHz frequency with CL14 timings, at a nice 1T command rate as well. So this merely was enabling XMP (or whatever it's called in your motherboard BIOS), and after your saved the setting and a reboot, our Ryzen 7 2700X booted absolutely stable into windows with these DIMMs installed.
3200 MHz (CL14)
3466 MHz CL14
Here is a surprise, value for money - 3466 MHz works by just enabling XMP 3200 and then change the DDR4 frequency towards 3466 MHz. Ironically this was not working on the Intel platform. That's really sweet.
