It makes perfect sense, a faulty/intermittent IMC, given you have tried different
boards and RAM, is the only component that can cause the symptoms you describe.

If it was RAM, that would mean you used 2 completely incompatible model kits. Even
then, they should have worked at 2133 in dual channel. The IMC is not a simple
circuit, it relies on voltage etc the same as the CPU and is also required to
run out of spec in order to achieve XMP frequencies.

You can try raising the RAM and related voltages by 0.01v then 0.02v up to
0.05v and see if that stabilizes the RAM in dual channel. There are numerous
tutorials out there on RAM overclocking and what voltages are related. However, if
this works then your IMC is definitely not working correctly. The reason I say
RMA the CPU is because intermittent can suddenly turn to completely dead.

You can also carefully check and clean the bottom of the CPU, dirt or residue on
the contact pads can cause the issues you are describing too but if that were the
case, it would be the same RAM channels not working on both boards (A or B).

I know it's inconvenient but it could save you a lot of headaches down the line.
If I am correct, and I strongly suspect I am given similar issues here on the
forums in the past, the IMC is not functioning correctly and could die on you
completely in time.
