[SOLVED] Memory CL 15 is not been applied, instead CL16 Need HELP!

[Vana Ivan Pandovski]

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.

with gear down mode enabled, u can use only even tCL

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

If you have it overclocked it’s probably not going to reach the cas latency that’s advertised.

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.

No even when I set the Default XMP @ 3000MHz with the timming 15 17 17 36 - 1.35v it doesn't apply them, it adds 16 17 17 36.

Well if you have it at 3200mhz cas 16 it’s the same overall latency as 3000mhz cas 15 so I wouldn’t waste time worrying and just enjoy your games.

Gear down mode disabled will allow you to run your odd numbered XMP settings. I had to do that for my cl17 3733 on my x570 board.
