Excellent for Ryzen Zen2 and Zen 3 CPUs
by Mr Alexander A WeatherbyI 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.
