This is true of both sets of 2x8G modules.
Where the original set of 2x8G sticks was clockable from the base 2133 to 3300mHz, the system will now fail to boot at any setting higher than base value. Testing any one stick of RAM in any slot where the PC will boot, the stick (and socket) passes memtest. When installing RAM in single-channel mode (A1-A2 or B1-B2) with one set of modules, the system recognizes both modules properly and both pass memtest, even when one of the modules would have failed in dual-channel mode. 
(while this looks like a bad slot, please continue reading)
In a dual-channel configuration, memtest will fault on the second stick of RAM - however, swapping the position of the two sticks results in memtest still faulting on the second stick. When known-compatible RAM (2x8G) is installed in a dual-channel configuration (A2-B2 or A1-B1), the BIOS recognizes both sticks, but Windows 10 reports 1/2 RAM capacity (8G) as 'hardware reserved'. It worked correctly when I built the system, but no longer does. The system refuses to run in dual-channel mode. RAM set 2: CMK16GX4M2Z2933C16 (purchased for diagnostics, not to run in conjunction with Set 1) The system is a Ryon an ASrock x470 Taichi Standard. I'm trying to diagnose a memory issue to determine if the problem is CPU or motherboard.
