I suggest you try and re-seat the CPU again. Bad pin contacts are a frequent cause for symptoms like yours.

Clear CMOS afterwards too.

yes. count 1/2 ram, but quad channel

I have buy 4 bancks of DDR4 for TR4. I have try, but always error.

quad channel but only 2° and 4° see memory.

CPU-z see 4 bancks, Aida only 2.

Reset bios many time, equal.

This week send to me new mother-board.
