I even got my 2 32G sticks in the same channel to 3600, but it wouldn't train with antyhing better than CL28 or therabouts. I heard that's likely due to the imbalance and/or quad-rank making the memory controller unhappy, as the PHY should be agnostic to the CL setting. I mostly just did that test to check if I'd have to give up the 3600 speed if I'd upgrade from 64GB 128GB on this 5950X; I'm well aware that one shouldn't be running it single-channel, especially not if that would mean quad-rank operation.
