Took a chance on a new brand. Usually use GSkill, Crucial, Corsair, etc. Most motherboards set them to 2133 by default. I set the XMP profile to 3000MHz but lowered it to 2933 for my Ryzen 1600 Zen+ rig. Running memtest86 overnight, no errors. CPU-Z lists the manufacturer as Micron (I didn't pull out the heatsinks to test). Use them on ASRock B450M-HDV R4.0 board.
