for the last time it doesn't work and yes i know how to use RDC

Most CPUs have a memory "hole" where its unable to train memory from 3350-3450 MHz up to 3500-3600. This means you might be unable to run 3400 MHz DRAM frequency but 3600 is OK.

i was about to try that i miss my old phenom that can't do 220fsb but boots fine with 250

did few runs last night with datonyb's suggestion with gear and power disabled on 3400-3466 no major changes except for cl15 being bootable but not stable.

Without detailed specific details of what you have tried it is difficult to say what you need to change, but considering I use a kit of G.Skill RipjawsV rated for 3200MHz @ CL15 when testing and can run them up to 3600MHz CL16 @ 1.4v and POST 3733MHz on a X470 Fatal1ty K4 it is safe to say there is no way that 4000MHz Trident Z kit is going to top out at merely 3333MHz unless A: The kit itself is faulty, in which case run HCI memtest for at least 4hrs to test them, B: The CPU has a crappy memory controller, or C: You have installed the memory kit in the wrong set of DIMM banks. Also possible is that you have damaged the memory kit throwing 1.65v at it (beyond 1.45-1.5v without active cooling is a really bad idea), and / or you are not using enough SoC voltage, try 1.05 - 1.1v.

Lastly, chill out you haven't provided much information on what you have tried to go on I merely gave some clarification in my last reply.

1.4~1.6v can be still used with with pasive heatsinks (with good airflow)
1.6~1.8v with active cooling
1.8~1.9v with LN2 cooling

1.9v is MAX safe voltage

@ket should be option B, auto soc doing 1.1. The kits arent damaged i usually error test them after tinkering around when i go to bed they are active cooled when i bravely do 1.45v+ 

could you give me your RDC profile @ 3466 & 3600 in the end of the day it could be that RDC gives me impossible settings 

last night's result was 103bclk 3433 cl16 full stable 1.4v but i'm not happy with these results and rolled back to 3200 fast settings post 1.50 bios really sucks not being able to load bios profiles really hurts T_T manually setting sub timings every time is a chore.
