Thanks to an insightful comment, I have managed to fix my problem! It was either spread spectrum or the d.o.t. (overclocking) technology by MSI. Disabling these settings in BIOS helped me get a way better setting (some milliseconds difference) -- now ntp and adjtimex work without warning about +/- 500ppm!
