ye tried that, tried one by one, then all of them at the same time, then part by part. I dont even try any other value only its own auto value. Weird, tonight ill try jedec values to see if it changes anything.

@Splave It is now ok. Just I wanna ask something else, you see the ram oc ive made in the previous post, now it is 4100 freq, same timings and tRFC 350. The problem is, iol values are 7-7 7-8 or 8-8. And gives better performance when 7-7 of course. But when I want to manually enter the values(nothing different, just the ones it sets automatically) it doesnt boot. And there arent much to change, rtls, iols, and offset. I just want to lock it to 7-7 which it sometimes already sets it automatically. Do you guys know what can cause this, or how can i solve it.

@Leeghoofd Agreed this bios is a lot better than the other 1.2X ones for cml. I couldnt manage to get tighter yet, and training cr1 is still hard. It is already good as it is, hopefully there will be some improvements.

Yeah 1.40 is amazing for cml it looks like. A lot better training. Dont know what changed for rkl. Also is there any bios with more settings unlocked? This bios is joke. At least there should be "Display Hidden OC Item" toggle. I m sure you all know what it did before. I have contacted Asrock support and their answer was: `Regarding your question, the BIOS options you can see are all the existed options, there are no options that are hidden.` I mean when I look at the bios settings, it is not, there are TONS of stuff hidden, also there is the layout for display hidden oc item, just its name isnt written, so for the devs, it is not even a hard thing to do. And I never understand why these support are never helpful. I mean why do you even lie? This board is not 70 bucks entry level works as intended board. Hopefully someone with knowledge will read and understand.

yeah thats no problem, i am doing that way after realizing that problem, but still isnt it weird?

11900kf, tried both 1.27D and H. I want to do manual overclock, why whould I wanna use xmp with this motherboard

If we do not enable XMP, almost nothing trains, is this intentional thing? For example If I enter everything from xmp profile, doesnt boot, or even 3600 cl17 doesnt boot, but then enable xmp, 4000cl14 boots easily (2x16 4000cl14 ram)

Interesting one, I have gskill 4000 cl14-15 2x16 ram. Xmp works with no problem, but when I enter the same values manually it just doesnt boot. I have 10900kf, I guess we are still waiting for cml optimized bios. Is there any ETA about that?

do you know what is changed?

There were some comments about they were focusing optimizing cml, is there any news about it?
