Careful when buying

On the manufacturer's site is a list of the specific motherboards that these sticks will work with and if you have one of those these are great value. If you have one that is not on the list then you have yourself some expensive slow 2133 MHz memory.
Excellent for Ryzen Zen2 and Zen 3 CPUs

I am running two of these kits for 32Gb dual-rank operation with a 3900X. After quite a bit of tinkering I got them running at 3800Mhz with an FCLK of 1900Mhz, timings 14-8-16-13, plus very tight subtimings. I did have to up the voltage to 1.5v, but this is fine for Samsung B-die. I tested the same settings with my son's 5800X and it is fully stable there as well. There's no point even trying to run these at 4400Mhz with Ryzen, as you lose the 1:1 ratio with the FCLK. 3800Mhz/CL14 is the dream. And these kits have delivered for me.
