I've been running CMK16GX4M2B3200C16 on an Asus Prime X370-Pro at 2933MHz with no issues, and have dropped the timings to 14-14-14-34 and get a completely stable system. Will check which version I get the chance. Haven't tried pushing it to 3200 yet, mostly because I hate waiting for those five boot attempts before the defaults are restored and I view 2933 as pretty good at the moment. Bios version 0604, but it was running at 2933 under 0515 as well.
