Are these kits single rank? I thought all 16GB sticks were dual rank but in this video published today by gamer's nexus, at the end he said 2 x16GB is best but mentioned single rank in that statement:

I would add that I asked Buildzoid during a livesteam which was better 4 x 8Gb or 2 x 16GB (bDie), and he said that it depended on the motheboard because some did not work well with 2 x 16GB configuration not passing DDR3466. I currently have 4 x 8GB and have got them back to the same settings including unlocked power limit on CPU with PBO on (but limited to x4 scaler whereas now I have the x10 option in F31e for Gigabyte Aorus Elite X570) + I am swapping out 3900x for 5900x which was preordered within minutes of the 2pm launchtime.
In fact I learned from Buildzoid that the 4 single ranks of 4 single sticks boost performance for Zen 2, so maybe this info is just news to gamer's nexus and they don't watch Buildzoid's videos on memory overclocking. Its why I purchased Patriot Viper Steel 4400 which has no chance to boot at XMP & you even need to change proODT from 53 ohms to 40ohms before it posts @ 3600MT/s.
Moreover I learned from Lummi (another youtube overclocker), that the 2 x 16GB kits are easier on the memory controller on the CPU and therefore can clock higher, even if the actual chips were binned exactly the same.
