My first Kit was problematic had to RMA and the one stick that worked, couldnt get past 3100mhz. (had random crashes at 3000 as well) This RMA kit, dont know wth is good about it. I pushed it until this time @ 3500mhz with C15 and crazy timings still is rock....

Might be a tempting buy for most but suggested to pay little more for DDR4 3200 CL16 one which is better for current Zen 2 CPUs.
