Good to hear that you've got it resolved and working!
My problem still exists: slot 2 isn't working.
If someone could give me a clue of what it is when I can run 2 RAM modules in dual channel but can do it only in slots 1 & 3, which means that there is no issues with socket pins because CPU sees/uses both channels. Moreover, I can use slot 4 with one module installed and it works.
The problem is that slot 2 is unusable. To sum up how it starts and runs:
1 RAM module in slots 1, 3, 4: works at auto settings (e.i. 2133), doesn't work at XMP1 profile of Corsair CMK16GX4M1B3000C15, but is fine and stable if I set manually 3200MHz and 16-18-18 for timings (note: need to adjust after choosing XMP profile, because XMP sets secondary timings also).
1 RAM module in slot 2: DOES NOT work under no conditions and neither above mentioned trick helps.
2 RAM modules in slots
1, 3: DO NOT work at auto settings (e.i. 2133MHz), but DO WORK only after I've set up memory speed and settings manually to 3200MHz and 16-18-18 respectively,
for 1 RAM module at first (in any slot, except 2). and after that add second RAM module.

So, any thoughts are highly appreciated.
P.S. The images show:
