    I recently bought and installed a new ASUS Z790 Gaming Wifi MB. I am using Gskill DDR5 memory. I have two(2) 16GB sticks, and two(2) 32GB sticks. All of the memory works individually, all of the memory works in single pairs (and either in A2/B2, or even A1/B1 config). BUT if I install BOTH pairs (16GB sticks in A1/B1, 32GB sticks in A2/B2, or vice versa) I cannot get past first boot memory check (power button led flashes fast indicating memory error). The sticks are the SAME in every aspect other than 16GB and 32GB. What could be causing this?
