Still faulty memory stick I think, had similar thing when I first built my x299 system. RMA memory and try again.
-i wouldn't say I am any expert so can't debate the theory, but not a new build and same 4 sticks worked in same system for however long, only noticed lack of 8 GB when benchmarked, and same 4 sticks work in other slots just running in God knows what mode right now. But maybe Ill start looking into Crucials warranty info too.
Is fast boot off in BIOS & fast startup in Win10 ?
-would have been on when all 4 slots/sticks worked, right now at default bios settings whatever those are after update of bios(im not re config overclocks and voltages as sort this out)
Maybe bent pins under your CPU ? -->
Started when you swapped CPUs --> too much pressure on the CPU or Uneven tightening of the CPU cooler screws maybe ?
Did
not start when swapped CPUs, started at some point after, but had my quad channel 32 GB with new CPU and GPU installed
If it makes a difference, there is "power" getting to the slots not recognizing sticks because the LEDs on the RAM light up in 3 and 4, just not registering. Whatever that means.
Right now all works "well" like this, just cant move the 1 stick to the left of CPU closer to the CPU to the right slot.
