After a week of use, I have no complaints. My ASRock X570 Phantom Gaming 4 wouldn't allow XPM profile higher than 3000mhz for these, but I manually overclocked them to 3200mhz and it is working fine, very stable. Ram testing resulted in 0 errors. I didn't try higher than that, cuz I'm happy with matching CPU speed (Ryzen 5 3600). They advertise tested up to 3733mhz, so it shouldn't be dificult for you to reach that.
