Hi, I have 16 gigs of ram 2x 8GB Kingston HyperX Predator HX430C15PB3K2/16 Hynix M-Die both are rated at 3000MHz @ 15-17-17-36 Profile 1 and @ 2666 15-17-17-35 Profile 2.
So my question is I load XMP profile and I save and exit and I am getting the 16-17-17-36 I cannot hit CL's as 15, 13, 11 etc., I can only do 12, 14, 16, etc.
So why is this, why I cannot use the original XMP CL's instead it goes 1 up.

So I believe you understand my issue here, can you guys explain to me why is this like that.
Also, my MB is ASRock B450M-Pro4, and CPU is Ryzen 5 3600 @ 4.2GHz all cores 1.350v.

Just because RAM is rated at a certain speed or latency, a motherboard has to support it. DDR 3000 is kinda low for Ryzen 3 generation. I’d recommend DDR 3600 but you also need a board to handle it. Pretty cheap motherboard, get what you pay for.

Well the ram is ok, I mostly do gaming tho, I have it overclocked 3200MHz @ 16-18-18-36 - 1.35v, but I cannot make the CL to 15 or 17 etc.
 
And if I turn off gear down off will it change or? I have Power mode; Disabled, gear down enabled and 1T is been selected. So in what order should I proceed to get the prime numbers as 13-15-17 exactly?
disable geardown, set CR to 2T, set tCL to 15
if it doesnt boot, u may need raise ram voltage (1.37 ~ 1.4 V)
if it boots, u can try CR @ 1T if your ram can handle it

geardown improve system stability

with my experiance cr 2t has always worked better for me. also if he is overclocking to 3200 mhz id set the cas to 16, just saying.
